Practice
Real-time MIDI practice analytics
Plug in any USB-C MIDI controller and the app grades how you play, not just whether you played the right notes. Onset spread, velocity evenness, pedal technique, and tempo consistency — the same engine the web Practice Room uses.
Reference
Offline-first reference
Every chord, scale, mode, and theory page from piano.org bundled into the app. Loads instantly with no Wi-Fi — perfect for the music stand or a noisy practice room.
Performance
Low-latency Core MIDI
Native iPad implementation through Core MIDI, not a webview. At 140+ BPM the framework round-trip alone matters — we target sub-10ms total latency end-to-end.
Curriculum
Adaptive practice plans
Take the diagnostic assessment once and the app builds a personalized practice queue across 9 chord types × 12 keys, graduating you up the tempo ladder as you hit 50% accuracy. The app won't let you skip ahead.
Sight-reading
Sight-reading trainer
Random staff notation rendered live; the app checks your accuracy, rhythm, and dynamics in real time. Wait-mode pauses until you play the correct note.
Progress
Practice session history
Every session syncs to a private dashboard: line charts for accuracy and tempo ceiling, heatmaps for weak keys, comparison overlays vs. last session and 30-day average.
