Efe&Deren's Times Tables

I originally made this app for my daughter who was struggling to learn times tables, and it really boosted her speed in passing the times tables tests at school. Now I would like more children to benefit from this app, and providing this app without any ads or in-app purchases, as well as no user data is collected, and no internet connection is needed.
The app has three modes:
1) Learn: This is basically a collection of times tables from 1 to 12. The child can any time come back to this mode, in case he or she would like to remember.
2) Practice: You can choose the times tables you want to practice, and use the numpad with large buttons to answer randomised questions. There is a scoreboard that shows the progress for each times table.
3) Play: 10 multiple choice questions, randomised from all times tables. 15 seconds to answer each question. The child can abort at any time, as well as retry as much as wanted.
Features:
- Safe: no hidden costs, no in-app purchases, no ads, no promotion, does not collect any user data
- Simple: Minimum number of settings, and minimum amount of text
- Audio clues in the practice mode (can be disabled)
