App Description
Easy to use and accurate tuner for electric and acoustic guitars.
Tune your 6-string acoustic or electric guitar with your device's built-in microphone. Standard tuning (EADGBE), Drop D and five more presets are included at no charge.
Tune one string at a time
Allow microphone access, then pluck a string. Use automatic string detection or select a string yourself in manual mode. Follow the pitch indicator as you turn the tuning peg, then move to the next string.
Tune by ear
Play a reference tone and match your string to the sound. Repeat playback lets you keep listening while you adjust.
Seven included tunings
- Standard (EADGBE)
- Drop D and Double Drop D
- Open D Major and Open D Minor
- Open A and Open A Minor
More tunings with an optional upgrade
The preset-tuning purchase unlocks the remaining 14 presets:
- Drop C and Drop B
- Open C, Open G and Open E
- Open C Minor, Open G Minor and Open E Minor
- DADGAD (D Modal)
- Half Step Down and Whole Step Down
- Low C and New Standard
- Compensated standard tuning at a fixed A4 reference of 440 Hz
Other optional upgrades
- Custom tuning: choose a note for each string, then save and reuse one custom tuning.
- Reference pitch calibration: adjust the A4 reference from its default 440 Hz to match another instrument. The fixed-reference preset above stays at 440 Hz.
- Remove ads: remove both banner and interstitial ads.
Each upgrade is a one-time purchase. The all-in-one purchase includes all preset tunings, custom tuning, reference pitch calibration and ad removal.
The free app contains ads. Custom tuning and calibration are separate from the preset-tuning purchase unless you choose the all-in-one option.
