FlashMathFlash
Master your math facts, one flash card at a time.
FlashMathFlash is a math flash card app for multiplication, division, addition, and subtraction with whole numbers. The goal is to help people of any age build a solid foundation in mental math — and it's especially useful for kids learning their "Math Facts," as they're typically called in modern curricula.
One-time payment. No ads. No in-app purchases. No account. No data collected. You buy FlashMathFlash once and get the whole app. We feel ads and upsells take away from the learning experience (and the fun), so FlashMathFlash has none of them — and it doesn't even connect to the internet.
How it works
You choose your Focus Numbers for the session — the numbers that appear most often on the flash cards. Then you choose a range of Helper Numbers, which are paired with your Focus Numbers to build the cards.
For example, pick 7 and 8 as your Focus Numbers and Helper Numbers 1 through 10. You'll see 7 × 1, 7 × 2, …, 7 × 10 and 8 × 1, 8 × 2, …, 8 × 10, shuffled and presented one at a time. Check "Commute" and the order may be flipped (like 3 × 7), but your Focus Numbers still show up the most.
- All four operations: drill one operation, or mix several together in a single session.
- Timed or by card count: race the clock, or work through a set number of cards at your own pace.
- Negatives and commute: optional toggles to stretch your skills once the basics are solid.
- Detailed score screen: see every card you answered, with the correct answer for any you missed, plus 🎯 accuracy and ⚡ speed ratings.
- Copy your results: share a session summary so you know exactly what to work on next time.
New in version 2.0
- Now on Android, alongside iPhone and iPad.
- Study Sheets: math-fact reference tables for all four operations, including a full multiplication grid.
- Session history: every completed session is saved on your device so you can see your progress over time.
- Sound effects and haptics, each with its own on/off setting.
- Dark mode and a layout that scales up for tablets.
- Your settings are remembered between sessions.
We recommend starting with 1 through 10 for each operation, then adding in negatives and 11 through 15 once you've mastered 1 through 10. Thank you, and do some math!
