Good but freezes sometimes

This is an amazing way to learn the digits of pi and my goal is to learn the 1,000 digits this app has to offer. The only negative thing is that sometimes it freezes either at the home page of the app or [rarely] while I'm in the process of typing the digits. Maybe also more digits would be good.

Good design, bad pi test app

There's a lot to like about the design of this. Colors and sounds. Great! 10 minute unforgiving timer? Not so much. I can recite 1,000 digits of pi in under ten minutes, no prob. I can even recite those digits BACKWARDS in 9-12 minutes. But to do so I had to train using other apps. Typing and reciting are two different things,and this app is too unforgiving. One slip and you're out. I wouldn't recommend this to anyone trying to practice learning pi. There's no practice mode. There's no untimed mode. It would be great to unlock achievements at every hundred memorized in untimed mode, and for time scores (100 in under 60 seconds! 100 in under 45! 100 in under 30!) There should be a "flawless" bonus, but also allow two strikes every 100 difits or so. Maybe bonuses for flawless streaks. And last but not least, how about a "backwards" mode, and a mode that tests place value? By that last I mean it asks you what numeral lies at a specific decimal plac. For example: 1? The answer is 1.
2? The answer is 4.
3? The answer is 1.
4? 5
5? 9
100? The answer is 0

This game might be fun if the player could stop the time clock or set it to any setting: 5 minutes, ten minutes, 30 minutes. Instead the game is always a five minute race against time. Since I can recite pi out to 900 digits and like to review occasionally, this game becomes, instead of practice, a typing test. Not fun. I would rather be challenged by my knowledge of pi than by how fast I can hit a keybord.
