Fantastic

Great app for practicing math facts. You can customize it to practice only one family of facts (1+0 thru 1+9 for example), practice all the addition facts, or anything in between. The same is true for the other operations. You can also select to do just addition, just subtraction, or practice both together. You can do the same for multiplication and division and can even practice all four operations together.
The app really shines in the tracking though. It keeps track of which facts you have a hard time with, not just in which ones you got wrong but also which ones took longer for you to remember and answer correctly.
The only issue Ive had so far involves multiple players. If you forget to select your name and take a test as another player, there is no way to throw out those results. This throws off the tracking and charts for that player. A way to eliminate "bad" tests would be helpful.
A simple way to help prevent this issue in your household is to make certain each player is using a different color theme so they will easily spot that they are using the wrong player ID.
Overall, a great app. Well worth the price and well be using it for several years.
