Full description

Numfly is a straightforward math trainer designed for anyone who wants to sharpen their arithmetic skills through regular practice. The app presents addition, subtraction, multiplication, and division problems and lets you enter answers using a clean built-in numpad. No typing on a keyboard, no distractions — just you and the numbers. Every answer gets instant feedback so you know right away whether you were correct. Over time you can track how your accuracy and speed improve session by session. There is nothing to sign up for and no account required. All your progress and statistics are stored locally on your device. The app works entirely offline. Customization is kept simple: choose a font size that suits you, toggle haptic feedback on or off, and switch between light, dark, or system theme. Pick one of the included avatar illustrations for your profile. Numfly is free, fully offline, and built for focused daily practice.
