Eidetic Notes is a focused mental math training app designed to build calculation speed and accuracy through structured, progressive challenges.
**Stage Mode**
200 levels organized across 10 stages of increasing difficulty. Each stage introduces harder arithmetic operations — from single-digit addition to multi-digit mixed operations. Exam levels appear every 20 levels to validate your mastery before advancing.
**Custom Practice**
Configure your own training sessions. Choose from four operation types — Addition, Subtraction, Multiplication, and Division. Set the digit range, question count, and per-question time limit to match your current skill level.
**Statistics**
Track your progress with detailed analytics. View total questions answered, accuracy rate, practice time, streak count, and a weekly performance chart to identify areas for improvement.
**Settings**
Toggle sound effects and haptic feedback. Reset level progress or all data at any time.
Eidetic Notes runs entirely offline with no ads, no subscriptions, and no network required. Just open the app and start practicing.
