A tuner that opens like a flower, plus a daily interval ear-trainer. Quiet, offline, on-device.
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.
Each session plays ten pairs of notes. Pick the interval — minor 3rd, perfect 5th, octave, the whole twelve. Mistakes come with a short reminder so you learn the shape. Your accuracy is tracked per interval.
Audio is analysed on-device using AVAudioEngine — nothing is recorded, persisted, or transmitted. No account, no cloud, no analytics, no third-party SDKs.
