MIDI fingerboard visualizer Load any MIDI file and watch the notes land on the neck, in sync with playback. | ✓ | ✓ |
Scrolling notation Pitch-accurate staff view scrolling beside the fingerboard. | ✓ | ✓ |
Chromatic tuner Cent-accurate tuner with reference pitches for every string. | ✓ | ✓ |
Scale trainer Play scales into your microphone and get told, note by note, whether you were in tune. | ✓ | ✓ |

Unlimited practice history Every session kept forever instead of the last seven days. | — | ✓ |
Intonation trends See whether your tuning is actually improving over weeks, not just how today felt. | — | ✓ |
Fingerboard heatmap Every note you have ever played, coloured by how in tune it usually is. The weak spots become obvious. | — | ✓ |
Practice insights Plain-language coaching from your own data — sharp bias, wide spread, weak fourth finger. | — | ✓ |
Streaks and goals Daily minute goals with a streak that actually reflects practice, not logins. | — | ✓ |
Arpeggios and advanced patterns Broken thirds, dominant and diminished sevenths, whole tone, blues. | — | ✓ |

Cloud piece library Save pieces with your markers and loops and open them on any device. | — | ✓ |
Export your data CSV and JSON export of every session and every scored note. Free on every plan — your practice record is yours. | ✓ | ✓ |

Does the free plan expire?
No. The visualizer, tuner, scale trainer, metronome and loop practice are permanently free and not limited by usage.
What happens to my data if I cancel?
Your sessions stay in the database and you can export everything as CSV or JSON at any time before cancelling. After cancelling you keep the most recent seven days visible, matching the free plan.
Is my music uploaded?
MIDI parsing happens entirely in your browser. Files only reach the server if you explicitly save a piece to your library, which is a Premium feature.
Does the microphone recording leave my machine?
No. Pitch detection runs in the page. Only the derived numbers — which note, how many cents off — are ever sent, and only when you finish a scale.
