Frequently asked

Is Mental Maths really free?

Yes. All six game modes, all 12 grade levels, and the full tips library are free with no time limits, no locked features, and no required login. The app shows occasional ads from Google AdMob (family-safe, non-personalized) to keep development going.

Does it work offline?

Yes. All training, stats, streak tracking, and the tips library work fully offline. Internet is only needed for ads to load.

Is my data shared with anyone?

No. We don't run servers — your name, grade, sessions, streak, mistakes, and preferences all live on your device only. AdMob does collect anonymous device signals for ads (configured non-personalized + child-safe). Full details on the privacy policy.

When will the Android version launch?

Android is in final testing and expected on Google Play soon. Email us at digiforcebusiness@gmail.com if you'd like to be notified at launch.

Can I use this in a classroom?

Absolutely. Mental Maths is designed for individual practice but works well as a 5-minute classroom warm-up. The Daily Challenge and Speed Drill modes are particularly good for whole-class engagement. There is no usage limit, no per-seat fee, and no sign-up.

How do I reset my progress?

In the app: Settings → Reset all progress. This wipes sessions, mistakes, and streak from your device. The name and grade can be edited separately under Settings → Name / Grade.

Found a bug or want a feature?
