Mental Math with Roza

Mental math practice for KG1 – Grade 6

Mental Math with Roza helps children practise mental math with friendly, timed practice sheets. It runs entirely on your device — no internet, no accounts, no ads, and nothing collected.

How it works

• Pick a practice sheet for your child’s grade, term, and week.
• Answer questions against a count-up or count-down timer.
• Review results, revisit mistakes, and watch progress grow.
• Parents can build custom sheets and view insights from the parent area.

The grown-up area — insights, custom sheets, profiles, and app documents — sits behind a simple parental gate, so it stays out of little hands.

Built for peace of mind

• Fully offline. Everything runs on your device — no internet needed.
• No data collected. Nothing is gathered, transmitted, or shared.
• No ads, no accounts, no sign-in.

When you write in, it helps to mention your device and what you were doing in the app at the time. Because Mental Math with Roza collects nothing, no diagnostic data is sent automatically — so the details you share are all we have to go on.
