TonalSnap: Intonation Trainer

Sing or play notes in tune

$3.99 · Designed for iPad. Not verified for macOS.

Train your intonation: save takes against a target note and see median cents and accepted samples, with a tuner and metronome. In the Musician's Toolkit bundle. Choose a target note and save a take that summarizes accepted pitch samples, while making weak, off-target or missing input visible. HOW IT WORKS 1. Open Intonation Takes in the Practice Lab and choose the note, concert pitch and tolerance. 2. Start a take with microphone permission. The app accepts only fresh samples that meet its input and target checks. 3. Stop and save the take, then review the median cents, accepted-sample percentage and rejected-sample count. The chromatic tuner, metronome and other practice tools remain available. WHAT TO KNOW A summary needs at least ten accepted samples. Percentages describe overlapping accepted samples, not time spent in tune. The app does not score silence as success. Device microphones, environment and instrument affect results; no calibration or real-room accuracy guarantee is made. iPhone and iPad.
