It's a one-time purchase (not a subscription) and supports Family Sharing. ■ For parents — designed for peace of mind • Zero ads (no banners, no full-screen) • Works fully offline; learning data and audio are never sent (processed on device) • Nothing is stored on a server • The purchase flow is hidden from kids, inside the parent PIN A kind, encouraging tone — a healthy learning experience you can confidently hand to your child. ■ Great for • Grades 2–3 (memorizing/cementing times tables, carry & borrow) • Grade 1 addition and subtraction • Early grade 4 division (Master Mode) Saying it out loud makes it stick. Five minutes a day builds fast, accurate calculation.

Stability improvements and minor polish. Zero ads, fully offline and no data sending — same as always. Five minutes a day is all it takes: practice times tables, addition and subtraction with the 10-question voice challenge.
