ttuner: tuner & metronome
Floats over your sheet music
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
New: bake the metronome click into your recordings, loop saved takes, and follow the bold timing cursor while you record.
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, and it adds +5 BPM every few bars while your hands stay on the instrument.
• 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.
Ratings & Reviews
• Bake the metronome click into your recordings — hear it in the preview before saving (saving with the click is a Pro feature).
• Saved takes can now loop during playback.
• A bold timing cursor on the recording timeline shows exactly where the beat lands.
• Timing fixes: beat lines while recording video, video A/V sync, and click accuracy.
