Love it! Timed mode is awesome. Just now I typed 180 digits of pi from memory at 282.72 digits per minute. So cool! I definitely prefer the in-app keyboard over my android keyboard, and being able to fine tune the width and height of it is such a great feature! My goal is to memorize 360 digits of pi. Did you know that the last 3 digits of the first 360 digits are 3-6-0? lol

The keypad within app is slow on my cellphone. If I type fast, the app starts missing key presses. There should be a way to get limited number of hints while practicing. App should figure out when user forgets few digits and types later digits of pi.

Great app. It also teaches you Euler's number, root 2, and the Golden Ratio. You can even import your own numbers.

About this app

Always wanted to learn the decimal expansion of pi or any other real number by heart? This simple yet powerful app helps you memorize hundreds of digits in no time. Featuring amongst other things a timed mode to improve on your and your friends' high scores and a fully customizable keyboard.

Just remember, knowing the first thirty digits of pi is enough to calculate the volume of the observable universe accurate to the size of one hydrogen atom. So who needs to know more digits? You of course!

The app includes the following numbers by default:
- pi;
- tau;
- Euler's number e;
- the square root of two;
- the golden ratio φ.
You can also add your own numbers. If you have any suggestions for numbers that should be included by default, feel free to let me know.

There are multiple training modes available.
- Practice mode lets you type out the number, notifies you when you're wrong and shows the total amount of errors made. You can change the starting position to focus on a particular part of the number.
- Reference mode shows all digits of the selected number. Add spaces at regular intervals to organize the number visually, or specify the number of digits per line.
- Complete mode shows you some digits and asks you to type the digits that come after them.
- Timed mode lets you type the digits from the beginning of the number and measures the time until the first error. See how many digits you typed per minute and improve on your achievements on the highscores page.

The app includes an optional in-app-keyboard, as the Android number keyboard has another layout than the calculator you might be used to. The key ordering, width and height can be adjusted to fully match your needs.

Thanks to Julien Freslon for translating the app into French! If you want to translate the app into your language, please let me know by sending an email.
