Tsumego Pro (Go Problems) APK 5.16

5 stars: Allows you to play on past completion of the problem. You can play and replay from the starting position and it will continue to indicate optimal plays when you want if you get stuck. I enjoy figuring out why the position is solved on my own, and that being easy with this app. I'm a beginner but find it better than the others I've tried.
4 stars: Pros: Ticks all the boxes for a solid tsumego app. Multiple playouts per problem (inc
3 stars: App looks good. Easy to use. But dropped stars as no explanation why moves are right or wrong. Maybe the idea is to absorb by gut feeling what is a good play? I'm learning the rules elsewhere and have the basics.
3 stars: so, i dont want to be negative. this app is great it doesnt have any crazy ads (yet) and has great content. the only problem is that when trying to solve a puzzle, if you make a mistake, the back button doesnt work all the time... also, some puzzles wont say they are completed, but when i try every single available move, it doesnt accept any of them.
2 stars: Problems are nice but not accurately ranked, which is unfortunate. Also, some don't show white's optimal defence. But what i miss the most is the possibility to edit problems or import my own. I'd pay for this feature and rate the app 5 stars, although it should be fairly easy to implement. Since I paid and i'll have all future problems for free, why can't I import some ? Thanks.
