StrumTune tunes your guitar, bass, ukulele and more — accurately, and completely free. No ads. No subscriptions. No accounts. Nothing is collected, and the app never connects to the internet. TUNE ANY STRING Play a string and StrumTune names it, shows how far off you are in cents, and turns green the moment it lands. The needle settles quickly, so you spend less time watching the screen and more time playing. CHROMATIC MODE Not every note is an open string. With a capo on, on a fretted note, or with an instrument that has no preset, chromatic mode reads any of the twelve semitones instead of forcing your note onto the nearest string. MANUAL MODE Prefer to tune by ear? Tap a string to hear a clean reference tone and match it. Works even without microphone access. 9 INSTRUMENTS, 25 TUNINGS Guitar (Standard, Drop D, Drop C, Half Step Down, Full Step Down, Open G, Open D, Open E, Open C, DADGAD), 7-string guitar, bass, 5-string bass, ukulele, mandolin, banjo, violin and cello. YOUR OWN TUNINGS Set any note on any string, save it under a name, and it is waiting for you next time. Edit or delete it whenever you like. BUILT-IN METRONOME 30 to 240 BPM, time signatures 2/4, 3/4, 4/4 and 6/8, tap tempo and an accented downbeat. The click is scheduled sample-accurately, so the tempo never drifts.
