Overtone: Tuner and Metronome

Sound better every session.

Overtone brings a tuner, metronome and drone together in one app for 22 instruments, plus sight-reading, theory and tools for teachers. It's powerful enough for professionals and simple enough for your first lesson. Pick your instrument once and everything is set up for you.

TUNER
• Fast, steady chromatic tuner that shows exactly how sharp or flat you are
• Strings mode for guitar, violin, cello, ukulele and more
• Equal, just, Pythagorean or your own custom temperament, with any A4 reference

METRONOME
• From a simple click to odd meters, accents and whole sequences
• Mixed meters are easy to build: no more fighting the app
• Save presets, control it from your Apple Watch, and see the beat on your Lock Screen
• Sync tempo with other apps and devices through Ableton Link

DRONE AND SOUND
• Play against a drone or chord in real instrument sounds until in tune feels natural
• Hear any note in any temperament, exactly in tune

PLAY IN TUNE WITHOUT GUESSING
• Watch your pitch as you play: green in tune, amber close, red off
• Record a take and get a clear report: how in tune it was and which notes need work

SIGHT-READING
• New melodies every time, written for your instrument and graded by level
• Overtone listens as you play and marks each note for pitch, timing and length

THEORY AND EAR TRAINING
• Drills for notes, key signatures, intervals, chords and scales
• Go beyond 12 notes: tune and train in any equal temperament when you're ready

FOR TEACHERS AND STUDENTS
• Set assignments as a link or QR code: practice time, exercises, theory drills or a sight-reading test
• Made for band directors and private teachers, with no accounts to create
• Students get their own dashboard; teachers get a gradebook
• Practice reports a teacher can verify, sealed so they can't be faked

SHEET MUSIC
