Description
PianoMirror helps you compare your piano performance with a reference recording. Record yourself, align the two performances, and see differences in timing and relative dynamics on a piano roll. It helps you find the sections where your playing differs most, so you can focus your next practice take on those moments.

Could you build this?
Partial Building an iOS app with an audio recorder and piano roll UI is easy, but polyphonic audio-to-MIDI transcription and dynamic time warping alignment require specialized digital signal processing.
What it would actually take: Requires an on-device ML pipeline (such as CoreML running Onsets and Frames or MT3 models) for polyphonic piano transcription from microphone audio, followed by Dynamic Time Warping (DTW) to align the user's audio performance against the reference MIDI/audio. Fine-tuning models to run efficiently on mobile devices with low latency is the main technical barrier.
