What is Multibit?
An app for grades 2–5: the times tables, parentheses and the order of operations, fractions and percentages. Kids first understand a topic — a picture and a simple trick — and then make the answers automatic in practice games.
Does it need an account or the internet?
No. Multibit works without an account and offline.
Are there ads or purchases?
No. The app is free: no ads and no in-app purchases.
How do I change the language?
Settings (the gear, top right) → “Language”. Choose English, German, Ukrainian or Russian — or the system language.
Where is progress stored?
Only on your device. If you delete the app, the progress goes with it. To start over: Settings → “Reset progress”.
How do I open every level at once?
Settings → “Unlock all levels”.
How do I turn off sound or vibration?
Settings → the “Sounds” and “Vibration” switches.
Is Multibit suitable for kids?
Yes. There are no ads, chats or external links, and we collect no data at all — see the privacy policy.
