Peach Ear Trainer

Peach is an ear-training app. It generates short exercises that ask you to compare or produce pitches, records your responses, and adjusts the difficulty over time. The training disciplines: • Compare Pitch — Two notes play; you decide which is higher. • Match Pitch — Adjust a slider until the note matches the reference. • Compare Intervals — An interval plays; you judge whether it is in tune. • Match Intervals — Adjust the second note to form the target interval. The algorithm narrows the cent difference between notes as your responses become more accurate. The Profile screen shows per-discipline progress charts, summary statistics, and trend indicators. The home screen shows a small progress sparkline next to each discipline. Settings: • Equal Temperament (12-TET) and Just Intonation tuning systems. • MIDI input from a connected keyboard or controller (Bluetooth, USB, or Network MIDI). • Multiple selectable sounds: piano, strings, sine wave, and others. • CSV export and import of your training data. Peach runs on the device. There is no account, no sign-up, no analytics, and no tracking. Training data stays on the device unless you export it manually. The same app runs on iPhone, iPad, and Mac. Data does not sync between devices automatically; transfer it via CSV export and import if you need to. There are no scores, levels, or streaks.
