Review details:

App version: Beta 11.2
Device:  Samsung S4 Mini
Operating system: 4.4.2

Summary:

A high quality feature rich app which is both well designed and produced and also well supported. It is a ‘must have’ app for the advanced chess user, especially as it is free. Casual players will be better served by other chess apps. 

AAC gameAcid Ape Chess is an app for android devices from the Belgian developer Acid Ape Studios. The app is still technically in beta stage which may explain why it is free, unsupported by adverts and with no annoying in-app purchases. However, don’t let the app’s idiosyncratic name or beta status fool you – it is a fully operational and sophisticated app aimed squarely at the serious chess user. The developer is extremely generous in offering it to users for free. Given the quality of Acid Ape Chess it really is a ‘must have’ for the advanced user.

Features

Acid Ape Chess is one of the most advanced chess apps in terms of the number and breadth of features available – it is an app with all the ‘bells and whistles’. It is difficult to know where to start but perhaps easiest to say what it doesn’t do.

Well, strangely, it doesn’t play chess itself directly. So the issue of strength of chess play is not strictly relevant as the app has no native (inbuilt) engine. Rather it acts more as a chess gui. This has two specific benefits:

  1. you can choose your own engine  – the app comes with three engines (Arasan, ChenAAC engines and Scorpio) all of which are reliable and well-known. But you can also easily install any other compatiable engine (both UCI and CECP / winboard protocols are catered for as is the Open Exchange format to give maximum flexibility). A comprehensive archive of free engines is available to download from here.
  2. hardcore enthusiasts can set engines to play against each other to test relative strengths (though be warned – this does tend to drain the battery!)

Depending on the individual engine, for the hardened user it is also possible to edit/tweak various settings typically including hash size, skill level, and number of cores used etc.

Practical game play is very well catered for with the ability to play blindfold games (a little AAC_game_screenfrustrating due to the temperamental voice recognition entry system), Chess 960 (where an engine is able to) and also interestingly simultaneous games so you can mimic the exhibitions of the top players! Games can be played using sudden death (ie game in x minutes) or Fischer time controls (ie base time plus increment per move) though perhaps a little surprisingly, move based time controls (eg 40 moves in 1 hour etc) are not catered for. Games are automatically saved for future reference and there is a good range of file management options accessible via the Database icon. This enables different pgn database files to be loaded and also individual pgn files to be externally shared and copied and pasted from the clipboard. The simple ability to easily transfer games between different chess apps via the clipboard is a surprising omission in many chess apps.

If you get bored with engine play Acid Ape Chess also acts as a client interface for major online chess servers, FICS and ICC. Functionality is generally good with most key actions AAC FICS gamereadily available from within the app. However, the ability to filter game search is currently an omission (I want to easily be able to specify the strength of opponent when looking for a game!). But it should be said there is also access to console mode so more experienced users can manage their use of FICS directly via the standard FICS commands

In addition to practical game play, Acid Ape Chess offers the user other possibilities. There are a suite of options for setting up, editing (via standard FEN notation) and analysing chess positions. Interestingly, these handle both Chess 960 as well as traditional chess positions.  There is also a dedicated tactical puzzles mode with 3 separate selection files with a total of 900 separate puzzles. These offer a good challenge for the experienced player and require you to solve the winning line move by move (hints are available and there is ready access to engine analysis for study purposes if needed). The puzzles are taken from real games and a nice touch is that the player details are also included. For added flexibility the user is able to also import puzzle collections and there are many freely available on the web.

In keeping with its aim to focus on the more specialist user,  Acid Ape Chess includes some more niche features which may be of real value to those who can take advantage of them. In particular, two worth mentioning are that the app offers:

  • connectivity with the DGT electronic chess board  via ‘bluetooth’ enabling games to be played directly on the lovely DGT wooden board for a more natural chess experience (sadly your reviewer can’t test this, not having access to a DGT board)
  • automatic integration of online Syzygy endgame tablebases (for up to 6 men)  which is invaluable for endgame analysis and practice (the benefit here is that mobile devices don’t have the storage capacity needed for the 6 men bases)

Practical use and presentation

Sadly it is all too common for apps with multiple features to be overly difficult and complex to use due to poor design. There is nothing more frustrating for a user than having a wide range of options if they can’t easily find or remember how to use them! This is not the case with Acid Ape Chess and the developer has clearly thought hard about the useability issues during app development.

AAC main screenAll the main features are available from a single well designed home screen  which is split into four theme areas:

  • Game (including engine play, puzzles and file management functions)
  • Position (setting up, analysing and playing )
  • Online play – covering FICS and ICC use.
  • Settings – including special features, engine management and options for making changes to visual aspects

Cleverly, all the sub-options for each theme are also directly available from the home screen by clicking on a small double arrow icon to the right of each theme area.

Navigation around the app is also straightforward.  A simple swipe system allows the user to move between different sections of the app which appear as separate open ‘multi-page’ windows – these can also be quickly accessed as a drop down list from a button on each screen. This means for example there is the potential to have several games open simultaneously and to switch between them for example when watching online and analysing.

AAC clocksThere are many simple and thoughtful touches to help the user – this includes the use of large digital clocks which is very helpful when playing blitz games either online or against an installed engine. The clocks don’t have to be visible if they are too distracting for you and the user can simply swipe again to display other relevant information such as a list of moves of the game etc.

Often the benefits of the design features only become apparent through more regular use. As a practical example, keeping a finger on the arrow keys speeds up the time control minute and second counters – important for setting up anything longer than AAC colour schemea blitz game quickly. In terms of customisation, a recent update to Acid Ape Chess has also introduced a good range of different board colours and styles together with several different pieces types to add some variation to the visual playing experience.

Notwithstanding all the positive aspects, I have one just one relatively minor gripe. When wanting a simple no frills game ‘mano a mano’ against an engine it would be nice to be able to play with just the board alone visible (preferably against a dark background) – ie  with reduced/no other information visible  – just the board – so I could fully concentrate on the game. Visually this might also give the impression of a bigger board as it can sometimes feel a little too small, for example when the oversize clocks are also displayed. The text font size is also rather small.

In addition to being well designed the app is also technically well produced. For such a sophisticated app (and notwithstanding its beta status) it proves reassuringly stable. This is not to say that it hasn’t crashed on rare occasions. But it is important to note that Acid Ape Chess is dependent on the chess engines the user installs into it – not all of which are necessarily 100% reliable or have the same features and options. And this is not always immediately clear. If problems are experienced, consider first if these occur when particular engines are being used. Also users may see a warning notification of high CPU usage and noticeable battery draining; in this case check whether engines have been left running and/or the relevant engine settings in use (eg number of cores used etc).

Developer support

At the time of review, Acid Ape Chess is being regularly updated (two releases have been made during the writing of this review!). Indeed the developer has announced plans for an even shorter release cycle. The good news is that the updates have been meaningful, improving functionality rather than simply fixing bugs.

Very pleasingly, the high quality of the app is equally matched by  the quality of the developer’s support of it.The developer is easily contactable via the app’s play store page and responsive to feedback as evidenced by the replies left to reviewers’ feedback.

Importantly, an active twitter account @AcidApeStudios is also maintained for news, feedback and support which is well worth a follow. (I’m always surprised more developers don’t use social media presence to promote and support their apps – maybe I’m following the wrong accounts!). As a last point, surprisingly there isn’t a support contact/feedback option within the app itself and this might be something worth considering in a future update.

AA Chess

AA chess1

Review details:
App version: 1.3
Device:  iPad 3
Operating system: iOS 9.3.1


Summary:

A simple app which has a few rough edges but offers a fun game of chess for the casual user

The developer of AA Chess (kargeor apps) makes the impressive claim in the app description that …‘AA Chess is the best FREE Chess app for the iPad, iPhone and iPod touch!’. Given the developer hasn’t got an established reputation in the field of chess software, it was a claim I was eager to test!

Leaving aside the key chess considerations for a moment, my initial impressions of the app were favourable. The developer deserves kudos to start with as the app is totally free being unsupported by adverts (frequent or otherwise), nor does it have any in-app purchase options.

Let’s cut to the chase … AA is a plain and simple chess app, without bells and whistles aimed squarely at the casual player AA chess splashscreen The app offers the ability to play chess in three ways:

  • against an in-built (unnamed) engine on one of three different strength levels,
  • online via Game Centre connection (not tested in this review);
  • in free play mode (effectively ‘pass and play’ against another human).

The most noteworthy feature of AA Chess is the presentation and display. The app has a 3d option which mimics playing on a table against a seated opponent (or rather empty chair against the cpu). 3d chess visuals are very hard to pull off well in terms of practical usability. In this case AA Chess makes a reasonable attempt – the graphics look quite impressive, certainly in the case of the main 3d piece set, which are clearly AA chess main 3ddistinguishable. The one area where clarity could be improved is perhaps in having a greater contrast between the black pieces and dark squares.

The user has some control over the view and with a finger can easily rotate the board a full 360 degrees to see the board from either side’s perspective. Disappointingly, however, there is no control over the vertical plain, so the user can’t alter the viewing angle or change the height . This is an important omission for a 3d board option as users are likely to have different preferences as to what angles give the clearest view of the pieces.

AA chess bq

Queen or bishop?

This weakness is particularly evident if the alternative 3d piece set is selected as it is pretty much impossible to distinguish a number of the different piece types from each other making the game uncomfortably and unnecessarily difficult to play. Adding to the confusion, although it is displayed in 3d the option is actually labelled as 2D-B.

 

Strength

Absolute strength isn’t likely to be a key issue for an app aimed at casual users. A range of levels with clearly distinguishable chess abilities and a focus at the novice/weaker end is generally the most important feature.  In this regard AA Chess is quite successful. There are three levels of play intuitively named as ‘Easy’, ‘Normal’ and ‘Hard’.

Using my stock engine opponent ‘Hiarcs’ which is considered to have reasonably accurate human elo playing level, I tested the app’s various skill levels. The ‘Hard’ level plays to a AA chess 2dreasonable club level standard  (about 1600-1700 level per Hiarcs elo) which seems well suited to the casual nature of the app. The ‘Easy’ level is indeed clearly weaker. However, whilst it lost a test game in 6 moves, it still probably plays a little too strongly for a novice level – for example it was able to beat Hiarcs at its 1000 elo level.

The AA Chess engine has a rather engaging and enjoyable playing style. It is fun to play and the obvious weaknesses feel quite endearing – for example, the engine has a noticeable desire to move its king towards the corner of the board (g1 or g8 square) in the early phases of an endgame. You can see a sample of games played by AA Chess for this review here.

Given the many chess apps available it is not that uncommon to find those including chess engines that are ‘bug ridden’ and which won’t play a legal game. In this case, it is worth noting that AA Chess has no problems in this regard and will play a valid game consistently obeying the rules of chess in full.

Features and practicality of use

AA Chess is a very simple. There is only the minimum range of basic functions required to AA chess optionsplay a game of chess. This includes the ability to take back moves and toggle app sounds on or off. There is also a  highlight previous move option which for some unknown reason uses a very distracting red colour to illuminate the relevant ‘to’ and ‘from’ squares. In terms of the information displayed during a game this is limited to a count of the number of moves played which rather oddly is the total game moves (ie including both white and black). Given its simplicity it would be disappointing if the app was not easy to use. In this case AA Chess doesn’t disappoint and the user can navigate between a range of simple menu options which are clearly labelled and also from an accessibility perspective, helpfully shown in a reasonable font size.

A final option perhaps worth highlighting which may appeal to users of social media is the ability to directly post (tweet) your game result to your twitter account. The app’s default text (below) can fortunately be edited should you wish to publicise your result!

Summary

So does AA Chess live up to its claim of being ‘the best FREE Chess app for the iPad, iPhone and iPod touch!’ – well no it doesn’t but it’s not bad for a casual game and there are plenty of apps that are worse.

Napo Chess

NapoChessReview details:                                                                           
App version:  0.7.7.1 (1 Jan 16)
Device:  Nexus 7
Operating system: 5.1.1


Summary:

An enjoyable and very simple no frills game of chess for the casual player but the functionality of online and database features is rather too basic for more serious use. 

NapoChess_2DNapo Chess is an Android only app from the developer Cronoscopium. It has been released in both Lite (free) and full versions. The latter is available for a small cost (£1.17 at the time of writing). The only difference is that the full version has 10 levels of play compared to 8 in the Lite version – these nominally being the two strongest levels of play. This review is of the Lite version.

The app is a simple chess playing application with some additional basic functionality including the ability to play on-line and review and play through a small database of games.

Strength

The app’s chess playing abilities seem generally well fitted and appropriate to the simple nature of the app. There are 8 levels of strength though rather unhelpfully there is no descriptive indication within the app about the estimated ability of each level.

diagram001

(A) – (nb not app image)

From testing, Level 1 is probably too advanced for the beginner (it is not clear if this is the objective). It offers perhaps a rather unrealistic style of play alternating between reasonable or even in some cases good moves to down right blunders. As an example, Level 1 reached the following position (A) as black after move 9 as has at least one International Master! The app’s opening book is quite small but switching it off altogether at the lower levels might help generate more realistic game play.

To get a better illustration of the app’s ability and playing style at Level 1, here is the pgn of a win it scored against the Hiarcs iOS app set at 1200 elo. (Hiarcs is generally considered to have one of the better and more accurate elo rating systems). With the above link you can also see and review some sample games played at different levels to give you a feel of the app’s broader play. From these and other games, I would estimate the top free level (level 8) to play at about the strength of an average club player (say 1500-1600 elo). So the majority of likely app users should find a reasonable opponent but stronger players probably won’t find it challenging. (Please remember the app’s full version has 2 further levels which may well be stronger than the Lite version tested).

Features

Napo Chess is enjoyable for what it is – a simple chess playing app. Don’t expect ‘bells and whistles’ because there aren’t any. However there are a few things worth noting. Practical game play has been made easier and more enjoyable by the inclusion of helpful and NapoChess_statisticssimple features such as a highlighting legal moves option and sound to signify when the engine moves. Additionally, the app has a statistics feature which keeps a record of the user’s score against each of the individual levels of play in the form of wins/draws and losses. This also includes an estimated elo grade which is a helpful feature for keeping track of progress and may have particular appeal to the competitively minded.

However, there are still a number of basic practical additions that would enhance a typical user’s playing experience. For example:

  • although there are clocks for each colour to record total time, there is no way to influence the time that the engine spends thinking. There are no timed levels of play or ‘move now’ feature to halt thinking. This is probably more important for the more difficult levels where the engine thinks for longer. (As a guide the average move time on the higher levels is around 15-25 seconds per move)
  • The user can resign or abort a game but there is no ability for the engine to resign. It isn’t generally difficult to program in to the engine, and would help to avoid the tedious situation where the user is forced to play out totally won games. The opportuntiy to accept and offer draws would also be similarly useful.

The app doesn’t just allow you to play chess against the engine. It has a 2 player game option and also includes an on-line play mode and game database option (comprising 910 games at the time of this review).  However, the very basic nature of many of these features make them difficult to use practically. In particular:

  • Online play – there is no ability to influence or control the game parameters; the user can’t choose the opponent or length of game. More than once I connected and found myself playing a 10 minute game when I just wanted a casual blitz game to pass a couple of minutes. Similarly if you already have a FICS account, the app doesn’t allow you to sign-in. Essentially, the user has only ‘Guest’ access rights but without the ability to challenge or accept opponents.

NapoChess_database

  • Game database – The user is only able to load and ‘step through’ and review single games at a time. There is no opportunity to be able to easily see which games are in the database without clicking through them all individually. The games are ordered by ECO classification; this might be useful if you are interested in a particular opening but isn’t much good if you want to see how many (if any) of Karpov’s games there are. Essentially there is no way to sort or manipulate the database.  As such as the database feature is only good for playing through individual games, but as the app has no engine analysis feature, it is likely to be of limited benefit to the typical user.

Practicality of use and presentation

Napo Chess is very simple to use. The controls are generally intutive and available choices clearly identified by either menu buttons or relevant graphical icons. The only exception to this, perhaps is the game database screen where the instinct is to press the highlighted game but this doesn’t actually open the game and there is no opportunity to move through the games by swiping.

The app doesn’t have a lot of choice or flexibility regarding presentation and layout. There are no options over board colours or piece sets. However, unusually the app does include the choice of a 3d view as an alternative to the traditional 2d view. NapoChess_3dIt is the 3d option which is a particular highlight of the app.  The smoothness of control and flexibility of the view in terms of rotation and degree of viewing angle is most impressive and one of the best I have seen. It is actually quite fun just playing with the orientation of the 3d board itself! The only criticism with the 3d usage is perhaps the sensitivity of the controls and also the choice of piece colours which are a somewhat dull an unnatural colour. Whilst there is no opportunity to vary the 2d view the board colours and piece types are well chosen and comfortable to view.

Developer support

A real positive is that the app is in active development with a history of regular releases. The developer has indicated that this will remain the case and it is an app worth both keeping an eye on and also supporting. With some further work it has the potential for inclusion in the chess enthusiast’s ‘keep me’ pile.

  • Limited practical use of the database
  • Lack of control over online play options

 

These are my thoughts; if you have used this app what do you think…..?

 

Mastersoft Chess

Mastersoft chessReview details:                                                                           
App version:  2.47
Device:  iPad 3rd gen
Operating system: iOS 9.1


Summary:

A good looking app that caters well for the casual user but won’t satisfy the more demanding chess player due to lack of features.  

Mastersoft Chess is available on both android and apple platforms. There are three versions. The Pro, is the senior edition with enhanced graphical Mastersoft_maincapabilities and separate ‘paid for’ and free releases of the app. The free version is not limited in any way but is supported by adverts. This review is of the ‘paid for’ version (ie not the Pro release).

It is important to credit the developer and note that Mastersoft Chess is a universal app meaning you don’t have to buy separate versions if you want to use it on a phone and tablet device on the same platform (eg iPod and iPad). This is very welcome from a user perspective.


Strength

The first thing to note even before downloading the app is that Mastersoft Chess promotes itself heavily on the basis that it uses a chess engine that came 4th in the World Micro Computer Chess competition.

On the face of it, this is great news. The engine must be a top strength opponent then?.. Well, the engine used is a version of Gromit Chess and yes, it is quite true that it achieved that 4th place position. Unfortunately, what the app developer fails to mention is that this tournament was held in 2001… an aeon ago in the world of computer chess. It’s as if you were being told England were the world cup winners on buying an England football shirt (maybe we can dream!). I have a particular gripe with sloppy and/or misleading promotional material and this is a poor example which should be corrected.

Nevertheless, despite this the chess engine is indeed a good one – with an established track record over a long period. Indeed Gromit has evolved over time and various incarnations and the engine author’s latest offering – called Ginkgo – is currently one of the top engines in terms of strength. It is not clear which engine version this app uses, but certainly if the latter then this would be something to mention in the marketing material!

However, in terms of core strength, the existing engine at its maximum level (the app includes an elo rating scheme – more of this below) will be more than adequate for all but titled chess players.

Features

Let’s start with features relating to actual game play.

Mastersoft Chess scores well with the inclusion of an elo rating function which allows the user to play the engine at selected elo ratings and also Mastersoft ratinghas a separate rating feature. The app will keep track of your elo over the games you play and visually graph your progress and also provide some rudimentary statistics about the games you have played. A good rating feature is important for a chess playing app. It gives an opportunity for the user to track his/her progress and can also maintain interest over the longer term by stimulating an element of competitiveness. ( I will reach and beat this app at 1700 elo!)

The user may select the engine to play at one of a large number of different strength levels. These range from 800 elo (beginner) to 2780 (Super Grandmaster). Whilst on the face of it, this appears to be very appealing, the practical application is maybe less so. The elo settings increase in steps of just 20 elo. This really is a spurious and unrealistic level of accuracy. Why? well because in practical play it is very difficult for the non-expert player to be able to distinguish a difference of 20 elo and it is even harder to program a chess engine to this level of accuracy, let alone throughout the ability range from beginner to Grandmaster. In short, the elo rating scale should be taken with a healthy pinch of salt.

There is also some doubt about the accuracy of some of the individual levels – for example the lowest level (800) ostensibly that of a beginner plays rather too strongly which is likely to demotivate players of this ability. It is noticeable that even at these lower rating levels the engine still uses an opening book and plays recognised opening moves. Use of an opening book at ‘beginner’ type levels can result in unrealistic game play if not specially adapted or better still removed. In this case, for example, the engine knows the main line of the Ruy Lopez rather too well for a player of 800 elo rating.

The app isn’t really suited for anything other than casual play. There are too many features lacking for the more experienced or dedicated player. This includes the lack of an analysis function (for example in reviewing games and/or positions). This is disappointing as the engine does offer analysis of its own thinking when playing a game. 

The app only allows play against the engine at the specified elo ratings. There are no time control based options (for example, game in 5 minutes or 10 seconds a move – the latter was certainly available in earlier versions of Mastersoft Chess). This isn’t really a problem for the casual or hobby player but it does mean that the user has no control over the engine’s thinking time at the higher strength levels.

So if you want to test your mettle at the top level 2780 (World Championship contender) or test the engine against another chess engine, you can expect the app to take around 30 seconds for each move. The thinking time per move becomes noticeable from above 2200 elo, so whilst irritating, this shouldn’t be a real problem for the average user. ‘Hard core’ users should also note that there is no ability to tinker with the engine settings, for example by altering book openings or style of play etc.

There is one particularly disappointing omission to note relating to practical game play and this is the absence of a resign or offer draw feature. Additionally, whilst there are save and load options, these can only be used directly from within the app. There is no import or export facility for either games or positions – meaning that these can not be shared or transferred for use in other applications.

However, Mastersoft Chess does have some good features. There is a veryMastersoft coach easy to use training mode which at the tap of an icon, will result in the engine either suggesting potential move options or warning of possible threats – these are highlighted visually on the board by either green or red arrows respectively. There are also additional play options namely the ability to play another human (ie 2 player option) and on-line play via connection to the game centre. In terms of the latter option, I have never succeeded in finding an opponent on-line (maybe I’m just unlucky!). So if you are just interested in internet chess there are other apps that cater for this type of play far better.

Practicality of use and presentation

The design and layout of the app is generally good and easy to use.  A variety of game control icons are readily accessible from the main playing screen. These are clearly identifiable below the chessboard – see below – and are those likely to be most commonly used when playing a casual game.

Mastersoft options

The app has probably one of the widest selections of board and piece options available. Helpfully these are pre-prepared in the form of a number of pre-defined skins, many of which have well matched piece and board combinations. This saves the user searching for their own though of course this is also possible for those wanting added variety.

There are certainly some visually attractive combinationsMastersoft_Staunton_3d including several well designed 3d sets (3D piece sets are notoriously difficult to show sufficiently clearly for practical use). Quantity of available options does not necessarily mean quality and several designs appear to have been included for ‘show’ and are unsuited to playing a game. However, despite this there should be enough choice to offer at least several that the user can happily and easily use.

Within the settings menu heading, there is also a range of options to tailor the look and feel of the game. For example, a simple coach option that flags up when you are in check, (but surprisingly not when you blunder a piece away!), speed of piece animation, and a toggle to display of captured pieces.

There are a few practical niggles with the app which become apparent with use:

  • The app uses clocks to record move times but these are redundant not only as there are no time-based levels to play the engine against but also as they only record the time taken for a particular move (ie they don’t show cumulative time, which might be useful for seeing how long  a user has taken for the whole game)
  • There is one frustrating design omission – the inability to use the app in landscape view, the user is restricted to a portrait view like it or not!
  • The sound option doesn’t seem to work (at least on my device I have never heard any sounds – and yes the sound option has been enabled and volume turned up!)
  • When saving a game, it would be helpful if the elo setting was automatically included in the game data field – to save the user having to remember and enter it

None of these are ‘deal-breakers’ in their own right but if fixed would improve enjoyment.

Developer support

Developer support for this app has traditionally been good with frequent updates. Feedback is actively invited and easy to give from within the app. which is always good to see from a user perspective. The app includes an easily accessible help file with detailed instruction manual. However, the bad news is that this is out of date (issued in 2009), and for example references features no longer available. The manual also makes no reference to users of the equivalent android app (I know as I also have the android app and it is the same manual!) . This really should be updated.


Overall

Likes:

  • Universal app
  • Effective design and layout
  • Variety of board/piece skins
  • Rating system enables user to track progress

Dislikes:

  • Misleading engine advertising
  • Unrealistic granularity of elo settings (20 elo gaps)
  • Inability to import/export positions and games
  • No time control based game options
  • Lack of draw and resign feature
  • Out of date instruction manual

These are my thoughts; if you have used this app what do you think…..?
