Pi Trainer: Daily Recall

How far can you go from 3.? Pi Trainer is a quiet place to learn the digits of pi and measure what you remember. Choose a number pad or speak with on-device English transcription. LEARN AT YOUR OWN PACE Start from the beginning. Get help in sets of five, correct mistakes without leaving the screen, and choose Retry 5 whenever you want another pass. Your entered digits stay available as the sequence grows. TEST YOUR RECALL Recall as many decimal digits as you can without a mistake. Review your full sequence afterward, with the incorrect digit crossed out and the correct digit beside it. Test history, personal bests, and run analysis help you see your progress. TYPE OR SPEAK Use the built-in number pad or say each digit aloud. Voice input grades digits as you speak, using supported on-device English speech recognition. Microphone and speech permissions are optional; typed input is always available. A LITTLE FURTHER, EVERY DAY Browse 100,000 bundled decimal digits. Track recalled and retained progress, set a goal, and build a regular learning habit. PRIVATE BY DESIGN No account, ads, analytics, or backend. Progress is stored on your device. Voice audio is not saved or sent to a recognition server. Designed for iPhone and iPad, with light and dark appearances.
