Chess Prep Pro Openings

loved it, perfectly customisable

This is great app but Can you make it so that I can read .png file from the Phone storage ?

This is the best app to create opening reportoire. And if I say best it is the best.

I like this app, it has no limit to add a move in repertoire I also like the new update where lines are randomly chosen

if you want to to have to deal with everything yourself get this app its caro kann course is particularly weak. app was somewhat slow and finally i edited my review cause i thought i forgot to mention get chessbook instead

Love every chess game I play.

It's really interesting how this app is able to teach basic chess opening through repetitions.

Amazing app for memorising openings!! 100% recommend. Even without any payments its still so easy and usfull to use

best for memorizing opening, defense

Great app, learning a lot.

An excellent choice for chess beginners! It’s completely free, easy to use, and offers everything needed to learn and improve. More advanced players can unlock additional features at a very reasonable price, making the paid version great value for money.

Very useful even for indepth analysis for different variation

actually quite good. exactly what I was looking for. free doesn't have tons of downloadable repos but a decent few and the rest you can just do yourself fine.

peak

It's a very good app for learning and practicing new openings and their variations.

I found it complex to use. Only 2 moves showed in queen gambit then said lines completed. Then nothing else worked. whenever i click cannot do anything till i force it to close.

this is great for players who are seeking for an opponent to play the move what we wanted

good

I thought this app is sucks but nahh i am wrong because i dont use it correctly so now this app is one of my favorite chess trainer this can save your moves and to memorize the variation even offline you can also build your own so this is a great saver for me thank youuuu.....

The best apk

Excellent for drilling your repertoires. I have tried different apps and always come back to this. The only issue I have is that the Repertoire visualization function does not show anything for some repertoires. Edit: Thanks for the quick response. Apologies for raising the issue: did a cleanup and reload of my repertoires and the visualization is working fine now for all. Changing my rating to 5 stars

Too many ads

need more opening repertories

Nice preparation app

This application teaches openings better than any other I have used.

👍

just hope after telling the opening it automatically suggests the variations

This is the best App for building your own repertoire

unfortunately it keeps hanging on my samsung fold making it unusable

there is not Option to Delete Mistake Move. example if I Want to Put e4 but accidently Move e3, I cannot Delete the e3 Move. Please help. tq thanks for reply.. I Found it!

I like the layout of this app a lot. Especially how easy it is to add moves to the repertoires. Is there a way to enable us play the moves each time? I like the repetitions for my muscle memory. I wish it was an option to allow that instead of it auto playing the previous moves in the line. Also, I like to look at the board for a little bit after the line is done to try and understand why I'm there. I wish there was a button to move on instead of it doing so automatically.

perfect for learning openings

useless

exceptional way to build your repetoire

Experience is very good. My suggestion is that there should be feature drill on saved puzzles.

Flawless!!

all I need in one app, 10M openings with win results, and Stockfish engine for analysis. And most of what I need can be done off line!

amazing

ABSOLUTELY TERRIBLE ADS EVERY 100 SECS

great

I love this game so much, bcz i learned a lot🥰

It's freezing every time, not sure if there are some bug fixes needed but please fix it, I couldn't really try it

the app works fine for me. All the basic features to work on my opening repertoires are here. Would be nicer if they allow more customization such as chess pieces selection and and perhaps changing arrow opacity in the future. Just a little more visual personalization.

Rubbish

Expensive but worth it if you want to get to 2k opening is very important

Good app

great way to train and keep track of strategies

Very good but from time to time it shuts down without any warning

very good but would be nice with more openings

very good for opening training I remember like every opening I want to learn it's amazing

horrible doesn't work on Android

it would be way better if it was free. or if there were other subscription plans rather than lifetime or yearly. 💔

amazing opening trainer. Very easy to use. works great all the time

Muy útil

This is the best app for organizing your opening prep it's really simple since you can also choose which variation you do first which helps to quickly memorize the moves this is also a very cheap app since even without the premium stuff it's still better than the other apps.

what the rule play i ununderstand

I try to import PGN files into the app but somehow it crashes. Please somebody fix it.

Great for practicing openings and gambits.

its is worth getting, however the interface is not user friendly, i want to split my scotch game to decline and accepted, there no duplicate, or rename repertoire :(

This app is VERY useful. I recommend it because of the repetitive ideas. I feel that the developers of the app did a really good job. It is very good for before-tournament practice. I really wish I knew of this when I started playing chess originally.

Perfect app, has everything you need. The blindspot finder is the best feature to find weaknesses but it’s for premium users but definitely worth it. The design of the app is very intuitive but the text is a bit small in some parts of the app. Another suggestion is to add more chess engines and be able to choose between them.

That's a Good app for Preparing chess...🙂👍👍✨✨💫

Does this app support chess engine to analyze positions? If so how?

its a really good app to review and memorize chess openings or prep

Advanced Training Mode Suggestion. I like the advanced mode because of spaced repetition but sadly, it forces to train the entire database instead of just specific vsriation. I believe it's better to have the option to train from specific variation at a time just like in basic mode. I suggest that Advanced Training Modes starts depending on the current board position for divide and conquer approach learning. Thanks.

Very useful for opening preparation.

no learning hrlp

very good at training a repertoire

excellent

Excellent app for chess repertoire training.

very helpful for beginners to intermediate

I don't understand — I just downloaded on a new phone, logged in with Google and expected it to download my previously downloaded repertoires but it didn't do that. So I go to the Downloaded Repertoires and noticed that it remembered which ones I had bookmarked on a previous device but when I click on one and hit the 'Download' button, it doesn't download the repertoires but instead it pops up a screen with an 'unlock' button telling me I must pay for Pro version?? Is this real or did I do wrong

This would be perfect except that the move animations make this unusable. It's a chore to follow what's happening when there is no pause between moves.

Really great app for training openings. My only wish is that you could set it to always quiz each part of the openings, even if you've done them before and it wants to speed up to the branch.

I'd give it 5 stars if it had more repertoires. However, you can upload lines from YouTube channels like Chess Vibes and create your own.

excellent app..but now the app is not responding,and your cc not responding to my mail,mine is the paid version

awesome for learning openings, interface could be a bit nicer tho

Excellent app for making repertoire and practise them

Great app to improve in chess

I have been using this app for opening practice but it was an awful experience because when I play all the correct moves it does not go ahead at all

non responsive already

Great app! wish there was a shuffle/randomize mode since training the entire repertoire trains each line in the same order so I'm memorizing what to do based on order and not the position.

Advanced Training Mode Suggestion. I like the advanced mode because of spaced repetition but sadly, it trains the entire database which is counter productive when database is moderately large. I believe it's better to have the option to train from specific variation at a time just like in basic mode. I suggest that Advanced Training Modes make the current board position as the starting point. That way we learn in divide and conquer approach. Thanks.

best app ever!!

Great challenges

the download of already existing repertoire is kinda useless cause it rarely gets updated and lots of even really common openings are missing. If you create your own openings, this app can be very useful and i use it often.

Worst app don't install

very good

Excellent way to study various chess openings.

I would even give 6 stars! Exactly what I was looking for and what it is made for! You can create yourvown openimg repertoires or download many existing openings. There is also a spaced repetition training mode.

okay

An app helps you get better at Blitz 👍🏽👍🏽

great app to expand your opening repertoire.

Tout ce qu'il faut pour les ouvertures

very good if you struggle with your openings in the 1000-1200 level

froze on the tutorial. couldn't even open the app after that. That's a pretty bad bug

Very Helpful and convenient for me since I'm always on the go and cannot open my laptop at any time for training, plus the app is even good for masters level.

It's so good to learn opening but it doesen't have a lot languange to choose.

good for preparing openings

Guys, pull up your socks. I'm returning (stumbled onto your app first) from an app that makes you look amateur; better interface, downloads your games to create personalised repertoire, better move trainer and even have flash cards. BUT they don't have your cataloguing system which shows available moves for both players for each turn, which does not seem much until you try to learn the most evil opening ever created, the Zukertort. Strangely, your app is the solution to their problem.

I have had this app awhile and paid for the lifetime plan. I must say it is excellent. I have tried changing my password recently but, I have not received an email to allow me to change or been able to create a new account. Please help? Thank you for all your help Incan now transfer everything to my new phone 😊

The updated version is a mess.. The app was fantastic 5 stars.. now it's full of bugs..bummer. Here is the big one..If I am working through a line and I want explore a sideline..I used to be able to select explorer mode then go back and look at a sideline...now the moment I select a move not in the curent repertoire the screen goes gray and I can only get out of it by returning to the home page..programming is hard ..good luck. they replied to me right away and fixed the issue great app again!

Not only is it a great spaced repetition app, I also use it a lot when reading chess books to write down variations. The UI is perfect for both tasks. ​Still, some details could be improved. For example, I would like to have an "explorer mode" switcher available easier than it is now, in the settings menu.

Are you considering to provide manage repertoire by sub topic also .. when list is long it is little difficult .. on android 15 in my samsung phone pgn select dialog still not working .. only list of pgn is shown but pgn file not clickable ..

Suggestion: This is a good chess app but I can't use it yet because of one serious issue: It trains all moves including alternative variations and blunders for my side to play. But I don't want to delete them because those are important information about what NOT to play. The simple solution is to make "chess prep" train only the "one and only" main move for my side to move and discard all alternatives. Thank you.

Great app easy to use. when I changed devices quick and easy transfer of my openings and no data lost... what happened during the last update? Openings get broken, and can't be used for training, and spend hours rebuilding the opening, train on it once only for it to break again. what's going on? very quick response from the developer with knowledgeable answers providing a fix for the short term. thank you very much.

Thanks for the 30k text, but now there's a new issue. I use opening courses, and some are expensive, which is a lot of theory or very valuable, so I store them in the app. The problem is, when I add too many moves—even though my account is unlimited—some moves disappear. Maybe what’s needed is to massively increase the PGN limit/repertoire text in repertoires. I’ll rate this 5 stars if you do. I don’t mind if the app gets laggy—I just want my full courses saved. Thank you for listening.

Great for a burgeoning beginner, but a brief animation confirming the correct move during training wouldn't go amiss!

excellent chess prep App! not only does it save All your lines but can also train you on all those lines without missing any & at the end of a line, it only resets from the point of deviation and continues with the training

Hats off to the developers — this is one of the best repertoire revision apps I’ve used! I do have one suggestion for improvement: It would be great to have an option to repeat a specific line multiple times during training. For instance, if I want to revise a particular line 10 or 20 times in a row, I should be able to select that line and specify the number of repetitions. This would be especially helpful for reinforcing tricky or critical lines. Thanks again for the excellent work!

I it is good for training your openings I wish there was a pc version. And you can delete some of the lines in the opening trainer.

this is the best app to learn openings, but i don't know why the app said my internet isn't good , it was good i was able to use YouTube but not access the "download repertoires" section, it worked after a few seconds though

I use this program almost daily. The way it plays through positions previously memorized in that session is instructive and time-saving. It would be highly useful if repertoires could be copied. large repertoires often need to be broken apart to learn, and copying would facilitate this. Another feature that would prove useful is the ability to reset streak stats for monthly tracking.

Great app but it would be more useful if you add features like an evaluation bar, point system and arrow system where we can add arrows to show the middle Game strategy. In many positions where the opening has ended and there are no direct attacks at that time this would be useful to show the ideas of White/black without a particular move order and also a folder where if we create 5 different variation of Sicilian then we can place it in a folder or else we have to train all the variations

Hey I played this on my phone, and it's heavenly! I wish could get this on my PC, so I can navigate easier and faster! Maybe make a website version, or a app for Google Play Games beta! Love this, thank you so much for your time and energy spent on the app!

I love the app. Could you add a FEN import so we can practice lines from a specific spot or make puzzles. This has great potential for puzzles too. Great app 👌

prob shouldn't be the only way to study opening but it is great for memorizing theory heavy lines in a some what fun way. absolutely recommend this app

App freezes on loading screen and repertoire is lost after uninstall/reinstall. Aside from that, app looks promising...

Very good app for opening preparation. Repertoire download is also useful. I wish I can group related openings in one folder for better organization.

Download the app last year (2024) I had fantastic experience with the app until recently it needed to be updated and i was having difficulties updating it.so i decided to delete the app and re-download it but when I log in my account all my repertoire where gone. All the hours I had spend gone. I thought my repertoire was save in this app even if I loss my phone but it seems I was wrong I have to start all over again ? How inconvenient. I don't want to lie this is demotivating as a player

This app is awesome for training openings. I don't buy a lot of apps, but went lifetime premium on this as it's worth it in every way. There are some annoyances, for example, I'd like more time to review my final move before it moves on. But that's very minor. Keep up the great work.

Great app for learning theory. Only one I've seen that uses active recall and you get so much stuff for free that others would probably charge for. Only thing that would be great is to integrate a spaced repition algorithm like flashcard apps such as Anki have. Even if it is a premium feature would be great.

It seems to be a straightforward app, as it does not need the pro version to give much area to learn, however the premium version is worth it. I like the simplicity of the app and that I can add my own openings, which are maybe missing from the explorer.

This app is very useful for me. I have two small improvement suggestions: 1. When completing a line, it immediately moves to the next. A brief pause with a 'Done' mark would be a helpful addition 2. The system should suggest the opening name as the repertoire name once created. Would these enhancements be possible? Edit: Thanks. I will purchase immediately once these implemented.

I have the full version and use it every day. This app is a game changer!! But to be truly perfect it still needs a SRS function like Chessdriller. Edit: I am so happy you plan to add it in the future! No other equivalent tool will be as user friendly as yours. Do you believe it' happening now in 2025?

UPDATE!!!! Original review -Looks like it is a good app, just on the samsung fold I cant see the bottom row of pieces 😕 Edited now! UPDATE. I was being daft and didn't see the part where you make the board smaller. I bought the lifetime for 17 odd quid that ain't bad at all for this. Please please keep updating very handy to have. Thank you for this. And so sorry for the original review.

Just input my first opening line that id like to learn from a video, very easy to use and I like navigating the visual map of what I input. The training feature is nice too. I think this will help a lot with my learning. Thanks!!

When i download a repetoire i dont want to have to name it, it should import the name and everything for me The screen goes grey during king moves in training, see tennison icbm. Id like the option to change board enumeration settins, side of board/top or bottom

I don't understand that app. It's true that I did not go through the tutorial, but I'm telling you that most users won't. Instead, the app should be self-explanatory to get more traction. My 2 cents.

I like the Idea how u train line on repeat but I want a missing feature to import study directly from lichess this make repo way to easy to make one more thin master databases is not updated if u improve this feature I give 5 star

Put a lot of effort and time into my repertoire, and now the app doesn't open it anymore. It's just stuck loading forever. EDIT: Got in contact with a developer, they fixed the issue in an update. Good interactions, professional and quick. It all works like a charm again. Great app!

Not for me as it seems to be for advanced players or those that can remember a repertoire. I couldn't find the computers examples.

I subscribe to premium version money debited but still can't use premium. Sorry to say this but the app was great the idea of replicating like chessbase replay training. This is not an user expect from a the app that he purchase a premium membership. If the payment and membership had gone flawless . I might have given you 5 ⭐

This is a really good way to memorize openings. I've been using this app in conjunction with another one to really expand y reprotoire.

Shoud i Complet a repertoire to get history and progress? There is something wrong in repertoire history progress, pls fix it.

Add an option to draw different colored arrows and highlite specific squares. Also to write in different colored texts in comments. This helps to note down ideas behind moves effectively.

Awesome app to learn and practice Opening and traps it not only tells the moves but also the theory and idea behind the moves. Hats off to the creators, I hope you guys bring more updates inthe future. Thanks a lot again!

It's a good app to practice chess openings. However, when you reach some positions from different moves order, sometimes, it doesn't recognize it's the same position, so you have to duplicate the movements in both "branches"

Haven't used all that long, but very good so far perfect for learning. Have a suggestion I plan on giving to support, if they fix it I will give it 5⭐

Great Stuff. The free Version offers plenty but I went with the lifetime premium (love it when this is possible) because of the failed positions Taining Feature. Only thing I am missing is spaced repetition.

The best app of its type. Great visuals and easy to use interface. There are a few issues, like the moves in the next move list disappear at times, they flicker on and off and the movement of the pieces back to the original or a different position is abrupt. It's a young app though and I'm sure these things can be corrected.

You are one step closer to greatness! We are hoping for cool features, including "adding graphical annotations" to the prep. Thank you!

Been looking for a great app like this that lets you store the opening repertoire that you studied and as a chess trainer to train these moves that you saved along with an engine to suggest you moves, this is the best all in helping you train with your chess opening repertoire and it's free!!!

Great app, but really wish there was a training setting to make it pause at the final move of a line. When I get the move right, it just immediately jumps to the next line before even showing the piece move, which makes it really hard for me to mentally retain be final position I'm trying to achieve.

It's a alright app let's you save your prep and tells the most popular move based on stats it also has a training mode where you memorise your lines in the correct order so a decent app overall

Fantastic app but after I accidentally uninstalled it I lost more than 60 per cent of my repertoire and I don't know where to ask questions.

Glad to know the app isn't abandoned, looks great and works better than ever. Update: there is an error (Could not connect to lichess APl server to get opening book.) Still 5 stars in my book though. Update: the reason was due to wifi, thanks for trying to troubleshoot the error with me

Horrible interface Just make it like chessbase reader or the old "analyze this" app. Simple user interfaces are just better. Also I cant see all my notes, variations and subvariations when I load a pgn. Just make it like chessbase reader.

Honestly‚ this app is exactly what I wanted for my opening's training. That's really simple to use‚ you can make as many sections you want to focus your work on whatever you want... Perfect !

Great app to learn the openings. Suggestion - In training, if a move played is mistake, it should show the further moves to clarify how that move leads to disadvantage.

Very helpful app! Would recommend, especially if you are a beginner to chess. It helps you build your repertoire, which is a really important factor when it comes to being a better chess player. It's super simple, not complicated at all. It offers repertoires free to download if you don't know how to build your own. Very customizable; you can change the color scheme to your liking. Also, it is very accessible even without premium. It's amazing!

Just installed it. Amazing really. I wanted to create my repertoire and used chessbase for that , but this app takes it beyond that to training too.

Very good. It doesn't keep track of which lines you know and which ones you don't, nor does it try to introduce one line at a time until you've mastered it. The app wants to train a whole set of lines every time which can be overwhelming. The app also has paid features like downloading pre-made repertoires, and finding blind spots. The free version does not limit you on how large your repertoire is which is a huge plus. The free version not showing blind spots is a real downer.

Just brilliant! It makes opening prep rather exciting. A feature I'd love to see is the option to train the failed positions. Similar to what is already available for the paid version, but rather than completing the entire repertoire, to choose train failed positions from the start. I reckon that ties into one of the reviews here on spaced repetition as it requires keeping track of the previous performances.

Really the best app. for opening preparation 👍 I have a question about the backup, is it possible to made one file backup for all the created repertoires? Or only one file at a time. For example, If i created 100 separate repertoires, should I make 100 back up pgn files?! 🙄.. Thanks

Nice app. However, the down side at the moment is that it does not support landscape mode (unable to rotate to support landscape view for tablets). Other chess apps nowadays are able to rotate to support landscape view/mode and comfortable to use in tablets.

Love it! I had a lot of time looking for a good app to enhance chess openings. With this app, you can use their repertoires or upload your own studies. Likewise, the interface is intuitive. It's similar to ChessBase for the tool to try openings, but it's easier to use and from your smartphone.

This is a by far the best repertoire creating app I have seen. It also provides lots of repertoires for people who don't know how to make one and keep complaining about not having the repertoirs for every single opening. The repertoires they give can be merged with yours making your repertoire wider and better. It said that by premium there will be no ads but till know I haven't seen a single ad 😂. One suggestion on my behalf can be to add puzzles related to the repertoire. Keep it up👍.

Very useful app, however the engine is not working, also it will be great if more settings added to the engine, thanks. Note : it's working now

For memorizing opening lines like traps, gambits, small and big chess opening repertoire with many lines this is very useful. Latest version of this app supports training from particular position onwards which greatly reduces training session duration. Developer has plans to incoporate more training features like ability to go through the learned lines multiple times and spaced repetition features. Support for endgame positions might also come in future I think thus app truly deserve 5 stars!

I tried a lot of apps for improve my skill in chess and that definitely the best one !!! For everyone who want to learn opening theory I recommend. Don't need to buy a book or watch yt video! Thx to this underated app

Wish I would have found this app years ago. Some ideas 1. Being able to annotate moves with blunder,mistake etc would be !!. 2. The ability to highlight squares and draw arrows. 3. Rename and rearrange the lines so you can choose what line the app defaults to if you just scroll forward. This can help distinguish the difference between main lines and side lines

The app is really vague about what it offers So on standard you can only download three repertoires? A day or lifetime? What is the price of Premium? Why do I need to insert my card number to make this purchase before finding out what amount I'll be paying like any normal app that just shows their prices once you click Premium? There are only 15 repertoires overall and there are repertoires of openings that other repertoires cover just on Black's side

I've been looking for something like this where I can build on my repetoirs. As a dev I thought I'd eventually have to build something simple myself for this. So far I'm absolutely loving it. Kudos man!

The app's great, easy to set up with the import options and I think that it is one of the best training methods, the app has already helped me gain 200 elo points

Love it but it needs improvement, it can't allow me to rename anything , you guys should make it possible to import a pgn file of multiple games that will be converted to 1 big opening tree , i can't find an app that does that
