Mini Math Dojo

Mini Math Dojo is a no-frills arithmetic trainer built for anyone who wants to sharpen mental math skills on the go. No account needed, no internet required — everything runs locally on your device.

The app covers addition, subtraction, multiplication, and division. Problems are served one at a time, and you answer using a clean built-in numpad. Each session tracks how fast you respond and how many answers you get right, so you can see your accuracy and speed improve over time.

Progression works level by level. As you get comfortable with simpler problems, the difficulty steps up naturally — larger numbers, mixed operations, tighter time windows. There is no single correct path; the app adapts to where you are.

Practice sessions are short by design. A few minutes a day is enough to build real fluency. The interface stays out of the way so you can focus entirely on the problem in front of you.

Stats are stored on device between sessions, so your history persists without any cloud sync or sign-in. Switch between light, dark, or system theme depending on where you prefer to practice.

Works entirely offline. No ads, no purchases, no registration.
