oTuner - Guitar & Bass Tuner

oTuner is a simple tuner for Android.
Just play a note and see the note name and how far off you are, in big, clear type. It covers 12 instruments and 33 tunings, from guitar, bass and ukulele to violin and shamisen.


- NEEDLE AND STROBE

- Meter: the needle and color show at a glance whether you're sharp or flat
- Strobe (FAMILY): the direction and speed of the moving stripes reveal drift too small for a needle to show
When you're in tune, oTuner shows "In tune" and gives a haptic tap.


- AUTOMATIC STRING DETECTION

In guitar and bass tunings, oTuner detects which string you're playing.
Tuned strings get a check mark, so you always know where you left off.
Tap a string to lock onto it.
