EasyGo - Tsumego, SGF editor

From the creator of EasyGo for iOS comes the ultimate Go (Weiqi/Baduk) app for Android — redesigned after 14 years to help you study, solve, and master the game like never before.
Whether you're reviewing your own games, tackling advanced tsumego, or learning joseki, EasyGo brings everything together in one powerful, beautifully designed tool.

MASTER GO WITH 2,400+ CURATED PROBLEMS
Sharpen your skills with 2,400 built-in problems covering fundamentals, life and death (tsumego), tesuji, and endgame techniques.
With 893 life-and-death problems featuring extensive variations, you'll explore every possible response — helping you develop a deep, intuitive understanding of each situation.

POWERFUL & UNIQUE STUDY TOOLS
EasyGo adapts to your learning style with multiple tools designed for efficient study.

• Problem Practice: Customize sessions by sorting problems based on how often you've attempted them, your mistake history, or success rate. Add variety by randomizing color and board orientation.
• Spaced Repetition System (SRS): Strengthen memory retention with our built-in SRS. After solving a problem, rate it as Fail, Hard, or Easy — and the app will schedule it for optimal review, just like smart flashcards.
• Interactive Joseki Practice: Go beyond rote memorization. EasyGo guides you through all valid joseki variations for both Black and White, responding to your moves and helping you understand the flow from both sides.
