EasyGo is a multi-function go software designed to help you improve your go skills and enjoy the go game:

1. Extensive problems bundled
EasyGo has total 2400 problems bundled ranging from basics, life and death, tesuji and endgame. And the 893 problems on life and death have extensive variations built in to respond to all of your possible moves.

2. A lot of ways to study problems

• Problem Practice - Sort problems by total tried times, wrong times, and win rate or shuffle problems. Random swap color and rotate board. If the opponent have multiple variations, you can tap the alternate move mark to switch to that variation.

• Problem Test - Take standard test(20 problems in 10 minutes) or custom test, in which you can customize the total problem number, test time. During problem test, the restart, try, show solution button are disabled. The standard tests for the bundled problems are integrated with game center leaderboard. Test history is saved automatically. And you can review all the problems answered incorrectly later.

• Spaced Repetition System - EasyGo includes a spaced repetition system (SRS) to help you study go problems more effectively. Basically, it works like this: you are shown a problem and you choose “Fail”, “Hard”, or “Easy” according to how well you know it. The system will automatically present the problem again for review in the future. That is, EasyGo works like a flashcard application.

3. Game records browse/edit/replay
EasyGo is also a SGF editor, supporting most of commonly used SGF FF4 properties, and features a node tree view, a variation table. You can use EasyGo to record your own games, create your own problems, and switch to problem mode to test at anytime.

A very nice Go app

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.

Great problem library

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.

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?)
