Great app The best I have find for Go so far. Apart from just playing Go, it also has many features that are very useful for learning the game and strategies. It has three levels for Tsumego (usually 1 to 5 moves strategy problems to solve), it also has recorded games of masters to study. Another big plus is the fact that it is Open Source. Also, the developer is very helpful and responds fast.
I would have found these MUCH sooner if they were listed on F-droid! How about some instructions? Maybe simple strategy? Alternate rules?
In tsumego, taken stones with 0 liberties don't disappear, not possible to finish many problems, e.g. Easy #3. Maybe stops working if you backtrack or take hint.
The app seems way more stable than Elygo for example, and which is my hallmark for graphics, I wish you could implement better colors and other textures for the stones.
When gnugo level 10 starts losing, it stops working. Otherwise, the app is ok for playing with friends.
The best go app I have ever seen
