Mathtasic for Android
For each mistake you'll be punished by ads)) And I have to change my review, because after a several days of using it I can say that sound reminder to play this game at midnight - it's too much!!!(((((
It's good and more improvement needed
This has different levels that adjusts automatically to challenge me to be better when I improve. Good for my daily commute to work.
