MetroTune: Tuner & Metronome

Tune your instrument, keep time and hear your progress. MetroTune brings a metronome, chromatic tuner and pitch practice tools together on your phone or tablet.

HEAR AND SEE YOUR INTONATION
• Pitch Replay: record a phrase and compare your original playing with pitch-corrected playback. Follow the tuner and pitch timeline as you listen.
• Pitch Accuracy (experimental): see a note-by-note tuning overview, with recent feedback for the note you are playing and a summary across the session.
• Pause to inspect a passage. Drag either end of the time range, move the whole selection, or expand the view for more detail.
• Adjust the minimum note duration for faster passages or sustained notes.

KEEP A STEADY BEAT
• Set the tempo directly or use tap tempo.
• Practice with subdivisions, swing, compound meters and polyrhythms.
• Build tempo changes with Tempo Map and train your internal pulse with silent measures in GAP mode.
• Choose from a variety of metronome sounds, use voice counting or start and stop with a double clap.
• Use the optional Louder setting when you need a stronger click, with your device volume buttons controlling the level.

TUNE AND TRAIN YOUR EAR
• Follow live chromatic tuning feedback while the metronome runs.
• Use instrument presets, transposition and an adjustable A4 reference.
• Explore Equal, Just and Pythagorean tuning, reference tones and an optional perfect fifth.
• Pitch detection is designed for one note at a time.

SCALE AND SCORE PRACTICE — PREMIUM
• Follow scrolling notation through scales, arpeggios and practice routines.
• Loop a selected passage, practice across keys and use Echo mode to listen and repeat.
• Listen mode (experimental) gives note-level pitch and rhythm feedback. Review the original recording with Pitch Replay and Pitch Accuracy.
