Flash: Mental Math
Fast mental math practice
Free · Designed for iPad. Not verified for macOS.
Watch numbers flash, add them in your head, and enter the total. Adjust the pace, save presets, review mistakes, and keep practicing your way.
Train your mental arithmetic with numbers that flash one at a time. Watch the sequence, add it in your head, and enter the total before the next round.
Flash keeps practice simple:
• Choose 1–7 digits and 2–500 numbers.
• Set the display speed from 0.1 to 3.0 seconds.
• Practice 1–999 rounds or keep going in Infinite mode.
• Turn answer input and automatic continuation on or off.
• Choose a light or blue background.
• Use sound, haptic, or both for feedback.
• Save your favorite settings as presets.
• Check accuracy, response time, streaks, and total training time.
• Review the exact number sequence for each round and retry mistakes.
Use it for a quick session or a longer challenge. Flash gives you a clear way to practice at your own pace.
