Flash Math

Simple flash card math. No ads, no subscriptions, no logins. Just getting better at mental math.

Pick a category, pick a format, and go. That's it.

Three ways to play: • 20 Problems — focused, untimed sets to build accuracy • Survival — answer until your first mistake, then beat your streak • 30 Second Rush — how many can you answer in 30 seconds?

Three categories: • Addition & Subtraction — single, double, and triple digit • Multiplication — every times table from ×2 through ×12 • Grade Levels — mixed problem sets for 1st, 2nd, and 3rd grade

Track your streak, accuracy, and total problems solved. Unlock achievements as you improve. See exactly how you perform on every multiplication fact and digit range.

Privacy first. All your progress lives on your device. Nothing is collected, shared, or tracked. No account needed, ever.

Optional upgrades — one-time purchases, not subscriptions: • Color Scheme Pack — unlock Dark, High Contrast, and five more themes • Lifelong Gold Member — advanced stats, color schemes, and everything we add in the future

The core app is free. The math is always free.
