Gacha Luck Tracker

Gacha, horse racing, pachinko/pachislot... any game involving probability. Do you just go by feel when you think "I'm winning" or "I'm losing"?

Enter the probability (or odds) ahead of time, and the app automatically calculates the theoretical expected value. Just record your actual investment and results, and the gap between theory and reality becomes clear in numbers and graphs.

• Three templates — Gacha / Pachinko & Pachislot / Racing — for quick logging • Automatic theoretical value from hit probability or odds, compared with your actual results • Organize records into folders like "My Gacha" or "Horse Racing" • Available in Japanese and English, synced across devices via iCloud

• This app does not let you actually gamble or pull gacha in any way. It is purely a tool for recording and analyzing your own activity.
