Intonation Master
Pitch & tuning for strings
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
See where your pitch drifts sharp or flat. Practice violin, viola, cello or double bass with live pitch feedback, staff notation and recording playback.
See what you play. Made for bowed-string instruments—violin, viola, cello, and double bass—Intonation Master shows your pitch on a live grid and displays the notes you play on a staff. Follow a phrase, spot where your pitch drifts sharp or flat, and listen back to your performance.
The free version includes up to 60 seconds of recording per take, playback, and recovery of your current take. Choose your instrument and key signature, then use the grid, notation, or both. The tuning reference is A4 = 440 Hz with equal temperament.
Unlock Full with a one-time purchase to record up to 60 minutes per take, save and name recordings, import WAV and M4A files, and adjust the A4 reference. Choose equal temperament, just intonation, or Pythagorean tuning. No subscription. Supports Family Sharing.
Audio is analyzed on your device. Recording works only while the app is in the foreground. Pitch detection currently covers 55–2400 Hz and does not include the lowest double-bass notes. Instrument presets adjust the display range, not the range of pitches the app can detect.
