Retune - Guitar Tuner

About

Retune is the tuner built around tunings. Pick Drop D, Open G, DADGAD, or any of eleven presets, play a string, and Retune hears which one you mean, no tapping, no guessing. When you land the note, you feel it: a tap and a soft chime, and you move on to the next string. TUNE BY TUNING, NOT NOTE BY NOTE Most tuners make you chase one note at a time. Retune loads the whole tuning: it detects which string you played, shows how far off you are in cents, and locks in when you hold it true. Tuning a guitar takes a minute, not five. FREE, AND GENEROUS ABOUT IT - NINE GUITAR TUNINGS BUILT IN: Standard, Drop D, Drop C, Half-step down, Whole-step down, Esus2 open, Open G, Open D, and DADGAD. - BASS AND UKULELE, FREE: standard bass (E A D G) and standard ukulele (g C E A) are built in too. - CHROMATIC MODE: tune any instrument to any note, with A4 calibration from 415 to 466 Hz. - STRING LOCK: tap a string to pin the tuner to it when you are dialing in something tricky. - A haptic tap and a chime when a string locks in tune, with four sounds to pick from. The core tuner is free forever: no ads, no account, works offline. RETUNE PRO: ONE PURCHASE, NO SUBSCRIPTION - CUSTOM TUNINGS: build and save your own presets for any tuning you play. - EVERY INSTRUMENT: the tuning editor covers 6- and 7-string guitar, bass, and ukulele. - METRONOME: a clean, accurate metronome with tap tempo, right in the app. - ICLOUD SYNC: your custom tunings follow you to every device you own.

MADE FOR REAL PLAYING - Reads your string through the mic with cent-level precision and a steady, jitter-free needle. - Microphone sensitivity you can set for a loud room or a quiet one. - Works offline, on stage or on the couch. - Light on battery, instant to open, nothing between you and being in tune. I'm one person, and I play. If a tuning you love is missing, you can build it in seconds with Pro, or say hello and it might ship built in.
