For parents
Not “they spent 20 minutes on it” — which skills they’ve mastered, which ones they’re stuck on, and whether that’s moving week to week.
Free to use
The whole question bank and unlimited practice. No card needed, and no trial that quietly ends.
Nothing to install
Works in a browser on a phone, tablet or laptop. No adverts, and no data sold.
Built for their exam
Foundation and Higher tiers, mapped to the GCSE syllabus — not a general maths app.
There’s an optional subscription at £1.49 a month for progress trends over time and targeted weak-spot sessions. Cancel any time — and plenty of students get what they need without it.
For teachers
Track which skills each student has mastered, spot gaps across the group, and focus your teaching where it matters most.
