About this app

Practice in tune and in time — without putting your instrument down.

ttuner is a chromatic tuner, metronome, and practice recorder built for musicians who actually practice. On-device pitch detection, an honest interface, and tools the way conservatory players use them.

TUNER
• Fast, accurate chromatic pitch detection — entirely on your device.
• Set your own in-tune range, in cents.
• Transpose and reference-pitch (A4) adjustment.
• 15 built-in instrument tunings — guitar, bass, violin, viola, cello, ukulele, mandolin, banjo — plus your own DADGAD, Drop C, or anything you invent. One tap to recall.

METRONOME
• Time signatures, accents, count-in.
• Speed Trainer: set a start and a target, choose the step and how long it lasts — a few bars or a few seconds — and it climbs while your hands stay on the instrument. Hold, loop, ramp back down, or stop at the target.
• Practice presets (Pro): save a whole setup — tuning, tempo, time signature, accents, splits and the Speed Trainer — under one name, and tap it to get all of it back.
• Float it over your sheet music in Picture-in-Picture (a thin floating bar on Android).

DRONE
• Hold any pitch, any octave, as long as you want — the way conservatory musicians train intonation. Plays behind your sheet music.

PRACTICE RECORDER
• Record your playing with the pitch timeline and BPM composited right onto the video.
• A practice heat-map — tap any day to replay what you played.
• Pro bakes the analysis into the file, so it travels with every share.

HONEST BY DESIGN
• On-device audio. No ads. No subscription. One-time Pro purchase, restored with your Apple ID.

Now in 15 languages.

What’s new

• Speed Trainer, opened up: set how much the tempo climbs each step, and whether a step lasts bars or seconds.
• At the target it can hold, loop, ramp down, or stop. Runs open with a count-in bar, and the floating window charts the climb.
• Practice presets (Pro): save a whole setup — tuning, tempo, accents, Speed Trainer — and tap to restore it.
• The click is now tuned to your reference A, so it no longer beats against your instrument.
