Swift Math Dojo

Swift Math Dojo is a focused arithmetic trainer built for anyone who wants to sharpen their mental math skills. No account needed, no internet required — everything runs locally on your device.

You choose the operation: addition, subtraction, multiplication, or division. The app generates problems scaled to difficulty, and you answer using a clean on-screen numpad. After each session you see how many you got right and how fast you responded on average.

The session history gives you a clear picture of your progress over time. Sort results by date, see streaks of correct answers, and spot which operation needs more work.

Designed with a minimal, distraction-free interface and support for light, dark, and system themes. No timers that stress you out — just one problem at a time, answered at your own pace, with the clock running quietly in the background.

Good for students reviewing fundamentals, adults keeping their arithmetic sharp, or anyone with a few spare minutes who wants something more useful than a casual game.
