And you can review all the problems answered incorrectly later.

Basically, it works like this: you are shown a problem and you choose “Fail”, “Hard”, or “Easy” according to how well you know it.

### 5/5 — 囲碁の問題の管理に最適

*2021-12-07*

詰碁や手筋、最善手など、囲碁の本や講座で学んだ問題の記録がとても簡単にできます。変化図や応手の分岐も作れ、複数の正解図を登録することもできます。階層別にフォルダ管理することもできます。proを購入すれば問題数の制限もなくなります。 また、定石モードで登録すると、白黒双方の立場で登録した全ての変化を問う問題形式で出題してくれます。 プリセットの問題に対して苦情を言っておられるレビューがありましたが、このアプリのメインの機能は、ユーザー自身が登録して問題を管理できる機能で、もともと入っている問題はおまけ程度に考えるといいと思います。 Androidではイゴロクというアプリを使っており、iOSでこのようなアプリを長らく探していたので、見つけた時はとても嬉しかったです。 機能面で言えばイゴロクの上位互換で、値段もお手頃なので十分購入する価値はあると思います。

### 5/5 — Terrific!

*2019-07-28*

This is the best Go study app on the market, hands down. The space-repetition study feature alone is worth every penny. Great support too. 

(Are there any more problem sets coming?)

### 5/5 — Great problem library

*2018-09-24*

This app has a great problem library.  Also, you can easily load Kogo’s joseki dictionary and interactively practice the sequences.

It’s too bad there is no version with a Japanese interface.

### 5/5 — Great Go Study Companion

*2018-08-28*

Ideal for study every day!  So many problems and they are well-organized. Also, spaced repetition is a very powerful tool.

### 3/5 — Good but crashes often

*2018-02-09*

Trying to open tygem games lead to crashes every time

### 5/5 — A very nice Go app

*2017-10-25*

Do the exercises included and you will definitely improve your level.

Also it helps when you review your own games in Tygem. 

The developer responds quickly and do listen to users feedback.

### 5/5 — Great update

*2016-08-25*

Update makes an already great app even better. Wifi transfer and enhanced tagging make it really easy to create and collect problems on your computer, organize them with tags, then directly load them onto your phone or iPad.

### 5/5 — Excellent learning tool

*2016-06-29*

The spaced repetition study feature is exactly what I've been looking for. Being able to add in my own problems and then study them has helped me learn more efficiently. The app has many nice features, but its study mode really sets it apart from similar apps.

### 5/5 — Helped me improve a lot

*2016-02-27, version 1.8.2*

This is my favourite app for studying tsumego ( I have tried several ) and especially making my own . 

You can download zip files of problems and unzip them really easily.

I  use the Spaced Repetition System where you can practice more difficult problems, as you judge it , more often than the easier ones . The SRS is fully customisable.

### 1/5 — Ce n'est _pas_ un jeu de go

*2016-02-10*

Ce n'est pas un jeu de go: mais une série d'exercices. Donc pas ce que je cherchais; le titre est trompeur.
