Math by Voice

Hear a math problem, solve it mentally, and say the answer. Math by Voice turns mental-math practice into short, voice-first sessions without typing. Choose activities with voice commands, start with addition, and unlock new topics step by step. The app combines focused practice with a structured course of 10 interactive lessons. The 10-lesson course progresses from mathematical foundations through arithmetic, fractions, formulas, equations, powers, and quadratic equations. Each lesson combines narration, visual explanations, interaction, and saved progress. Features: • voice navigation and spoken answers; • addition, subtraction, multiplication, and division; • squares, roots, fractions, and equations; • a structured course of 10 interactive narrated lessons; • mathematical terms and definitions; • difficulty levels, timers, and configurable sessions; • progress, streaks, and performance statistics; • English and Russian languages; • support for iPhone and iPad. Microphone and speech-recognition permissions are required for the voice-first interface. Recognition is provided by Apple and may require an internet connection in some situations. The first lesson and addition practice are free. A one-time Full Version in-app purchase permanently unlocks the remaining lessons, practice activities, terms, and Mission to Planet X.
