Needs Improvement – Tsumego Pro (Go problems) Review

I picked up this app to learn how to play go. Unfortunately, on my second time using it, one of my easy daily problems was literally unsolvable. I tested each spot on the board twice, and each time I was told my play was incorrect. I believe this app is better suited to players who are already semi-proficient at the game. I don't recommend it for new players.
