Numex Blaze

Numex Blaze is a math trainer built for anyone who wants to get faster and more accurate with mental arithmetic. No account, no subscriptions, no internet required — everything runs locally on your device.

The app presents arithmetic problems across a range of difficulty levels. You answer using a clean on-screen numpad, and the timer tracks how quickly you respond. Over time you can see how your speed and accuracy develop.

The home screen is organized as a grid of sections so you can jump straight into practice, check your stats, or adjust settings without digging through menus. A PIN lock keeps the app private if you share your device.

You can configure font size, first day of week, and interface language from the settings. All preferences and session data are stored locally — nothing leaves your device.

Designed to be distraction-free. No ads, no popups, no sign-in walls.
