No ads. No paywalls. Just fast, accurate guitar tuning.
OpenTuner is a lightweight, sleek, and professional guitar tuner built for players who just want to tune and play.
I made this app after getting frustrated with tuner apps packed with ads and subscriptions.
Why you'll love OpenTuner:
- Instrument mode for automatic string-by-string tuning
- Support for Bass, Banjo, and Ukulele
- Open mode for live note detection
- Multiple built-in tunings
- Create and save your own custom tunings
- Built in metronome
- No ads.
- No account required.
- No tracking.
Just open the app, tune, and play.
