FEATURES
Timed Tests
A daily 60-second challenge plus sprints, a two-minute marathon, per-operation tests, and a hard mixed test — at four difficulty levels, each with best scores.
Custom Trainer
Pick a number domain (Times tables, Natural, Decimal, Money, Huge), choose one or more exercises, and set per-exercise difficulty from Easy to Super hard.
All the Operations
Addition, subtraction, multiplication, division, squares, square roots, fractions, percentages, and modulo.
Mental Math Tricks
Dozens of step-by-step tricks for faster addition, subtraction, multiplication, division, and squares — with worked examples and favorites.
Practice Any Trick
Every trick comes with a 60-second drill built for it: × 11 drills, squares ending in 5, numbers near 100, and more.
Magic Square
A number puzzle: make every row, column, and diagonal add up to the same total. Four levels, from 1-9 up to bigger number sets.
Progress Tracking
Solved totals, accuracy, best run, daily streak, longest streak, and a weekly activity view.
Fast Sessions
An on-screen keypad with instant answer checking and haptics.
No ads. No paywalls. No account required.

Fixes
- An answer typed in the last second before time runs out now counts
- The Results screen no longer shows the round's close button
- Removed the Sound effects switch (the app has no sounds, so it did nothing)
- Better VoiceOver support and layout on iPhones with a home indicator
