Say the answer out loud — that's the whole drill. “Voice Math” is a voice-answer math drill for elementary school. No pencil, no paper. In quick 10-question time attacks (a minute or two each — five minutes a day is plenty), children practice times tables, addition and subtraction with great rhythm. Free: tables 1–3, addition and subtraction. A one-time Master Mode purchase unlocks tables 4–12 and division. ■ A new way to practice math — by voice Read the problem on screen and just say the answer. The built-in iOS speech recognition listens, and a gentle, forgiving check captures correct answers. If it can't hear clearly, switch instantly to a calculator-style tap pad. Children can answer in English, Spanish, Chinese (Simplified or Traditional), Korean or Japanese. ■ Free • Times tables 1–3 • Addition (including carrying) • Subtraction (including borrowing) • Time attack and best records Plenty for memorizing the times tables and practicing carry/borrow. ■ Master Mode (one-time purchase, no subscription) For families who want more, a single purchase unlocks: • Times tables 4–12 and division • Per-table “Progress” (mastery shown as stars) • Automatic weak-spot detection from mistakes and answer time, and adaptive practice that steers the next questions toward weak spots • Parent report (days played, day streak, accuracy per table, recent trend) • Sibling profiles (separate records per child) Purchasing is only inside the parent PIN gate, so kids can't buy by accident. 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 offline, even in airplane mode. Learning records stay on this device — the app has no servers or accounts (speech is recognized by the built-in iOS engine) • No sign-up, no analytics or tracking SDKs • 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.
