Lots of problems – Komodo Abacus Math Program Review

As others have stated, paid version still has ads. The UI is not that smooth either. Gestures to rapidly move top and lower beads were unresponsive. Even slowing down many gestures were not recognized. The addition quizzes work well but the algorithm for subtraction has a bug. Obviously, calculating 2-6 or 3-4 is not possible on the soroban. Since the developer seems to have no interest in updating this app, it is probably best to avoid it. I will obviously change my opinion if the developer becomes active in making changes. ---------- Update 7-9-12 The latest update did not solve any of the major problems this app has. At present the app is completely broken and useless, which is unfortunate because it was one of my favorite apps.
