PitchGarden: Chromatic Tuner

PitchGarden is a calm daily practice space for musicians. THE TUNER Open the tuner screen, play a note, and watch a small flower at the centre of the screen open its petals. The closer you are to in-tune, the wider the bloom. A precise cents readout sits below the flower for fine adjustment. Reference pitch (A4) is adjustable from 430 to 450 Hz. THE EAR-TRAINER Each session plays you ten pairs of notes. Pick the interval — minor 3rd, perfect 5th, octave, the whole twelve. Mistakes come with a short reminder ("That was a Perfect 5th — Twinkle, Twinkle") so you learn the shape. Your accuracy is tracked per interval so you can see which ones still trip you up. A QUIET PRACTICE LOG Stats shows your daily streak, last-seven-days minutes, and a per-interval accuracy table. No badges, no chimes, no notifications you didn't ask for. PRIVATE BY DESIGN No account. No cloud. No analytics. No third-party SDKs. Audio is analysed on-device using AVAudioEngine — nothing is recorded, persisted, or transmitted. There is no network traffic. WORKS WITH WHAT YOU HAVE • Any iPhone with a microphone. • Apple Watch — standalone interval flash-card drill, doesn't need your phone. • Home Screen Widget showing today's streak and weekly minutes. • Live Activity on the Lock Screen and Dynamic Island showing the current note while you tune.
