Twangle: Guitar Tuner

Twangle is a guitar tuner that also tunes bass, ukulele, violin and more, with every feature free. No ads, no account, no in-app purchases and no tracking. Twangle doesn't even have permission to use the internet: the sound from your microphone is analysed live on your phone and never recorded or sent anywhere. Twangle is simple to use and precise to a single cent. Play a string, and Twangle shows the note and how far it is from being in tune, on a big clear meter. "Tighten" or "Loosen" tells you which way to turn the peg. Once you're in tune, Twangle helps you play: it names the chords you strum, shows chord charts and scales, works out the capo, trains your ear and keeps time.
