Description
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.

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
