Peach Ear Trainer

Peach is an ear-training app. It generates short exercises about pitch and timing, records your responses, and adjusts the difficulty over time. The training disciplines: • Compare Pitch — Two notes play; you judge 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. • Compare Timing — A short rhythmic pattern plays; you judge whether a note came early or late. The algorithm narrows the cent difference between notes as your responses become more accurate. In Compare Timing it narrows the timing offset the same way. 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 and iPad. 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.
