Tonecraft is the practice tool every musician reaches for daily — a precise chromatic tuner, a sample-accurate metronome, and a reference tone studio, wrapped in a calm, modern interface that gets out of your way.
HALO TUNER
Fast, low-latency chromatic pitch detection with a clear, legible target. The signature Halo ring locks and blooms the moment you land in tune, so you can read your pitch at a glance — note, octave, and cents at once.
• A4 calibration (415–466 Hz)
• Transposition for B-flat, E-flat, F and more
• Instrument modes for string, wind, and voice
• Adjustable in-tune tolerance (±1 / ±3 / ±5 / ±10 cents)
• Graceful "listening" and "too quiet" states
PULSE METRONOME
A steady, drift-free click built for real practice.
• 40–300 BPM with fast ±1 / ±5 / ±10 tempo stepping and tap tempo
• Simple and compound time signatures (including 6/8, 7/8, 5/8)
• Subdivisions from eighths and triplets to quintuplets and sextuplets
• Per-beat accent editor (strong / normal / mute)
• Visual beat indicator and haptics
DRONE & REFERENCE TONES
Sustain a reference pitch or interval for intonation work, ear training, and warmups.
PRESETS
Save and recall your tuner and metronome setups for each piece, instrument, or ensemble.
PRIVATE BY DESIGN
Tonecraft works entirely offline. The microphone is used only to detect pitch on your device — audio is never recorded or uploaded, and the app collects no personal data.
Whether you are a student, a gigging player, or a teacher recommending one tool to a whole studio, Tonecraft keeps the essentials accurate, fast, and a pleasure to use.
