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.

Build a little riyaz into your day. Pick a taal, set your tempo and Sa, and practise with tabla, tanpura and lehra that return to sam every cycle. Dha brings together 28 accompaniment cycles and 41 guided tabla lessons on iPhone and iPad, plus a taal keeper on Apple Watch. Start free with five Foundations lessons, a playable dayan and bayan, sam, tali and khali markers, tanpura, lehra and a taal-aware metronome. PRACTISE WITH ACCOMPANIMENT • 28 bundled taal cycles, including Teental, Keharwa, Dadra, Jhaptaal, Rupak and Ektaal, with sam, tali and khali shown on a taal clock. • Set tempo and Sa, tap the tempo in, and mix tabla, tanpura and lehra. • A metronome that knows the taal: a click on every matra, strongest on sam and softest on khali. Turn the theka off for a click-only or lehra-only loop. • The lehra (nagma) is a simple synthesized loop through a chosen scale that keeps the cycle; it is not a raga performance. • Roman or Devanagari bol notation, an AUv3 instrument and MIDI input. MEET YOUR TABLA Explore the pair, dayan and bayan in an original visual guide with synthesized reference sounds, then open the related Foundations lesson. Physical stroke technique still needs practice on real tabla with a teacher's guidance. A GUIDED PATH 41 structured lessons in eight modules cover thekas, kaydas, relas, layakari, tihais and accompaniment. Each lesson gives a practice target, common errors to listen for, and a teacher or self-review checkpoint. Dha returns you to your saved lesson and tempo. UNDERSTAND THE TIMING Optional microphone checks estimate pulse, relative spacing, tempo consistency and return to sam. The estimates are experimental and may be wrong; quiet, clipped or uncertain takes are left ungraded. Dha does not recognize correct bols or verify physical technique. FREE, THEN LIFETIME Accompaniment, the metronome, tanpura, lehra, the five Foundations lessons, AUv3, MIDI and your practice history are free. Dha Pro adds the full 41-lesson course, unlimited experimental timing checks, private on-device Coach drills and the pattern composer. Dha Pro is sold as a one-time Lifetime purchase: pay once, no renewal, restorable, and available to Family Sharing. Where the app still lists monthly or yearly plans, they renew automatically until cancelled; manage them in Settings > Renewal & cancellation. Buying Lifetime does not cancel a subscription for you. No account is needed. Practice audio and coaching stay on your device. Dha is a Playsoloist app and a companion to your tabla practice. A real teacher still matters.
