Afinora: A Music Trainer That Grades Every Note

Field notes

The app maps exercises onto the player’s selected instrument and tuning, then listens through the device microphone while grading pitch and timing separately. Its practice system can turn pasted plain-text exercises into routes, accelerate or reduce tempo based on performance, and retain a history for each scale. The metronome spans 30–300 BPM with subdivisions through sixteenths, while the tuner supports reference tones from 432 to 442 Hz.
