Features: • Real-time pitch detection using your microphone • Clear cents indicator for accurate tuning • Standard and alternate tunings • Custom tunings for your own setups • Reference tones for each string • Adjustable A4 reference pitch • Ear training for notes and intervals • Dark and light themes • No external ads Available in 9 languages: English, Spanish, Italian, French, Portuguese, German, Japanese, Simplified Chinese and Russian.

  • This app hasn’t received enough ratings or reviews to display an overview.

New in this version: • Rebuilt pitch detection — notes are recognized on the first pluck and stay rock-solid while the string decays. • Much better with quiet instruments, including unplugged electric guitars. • Fixed strings being misidentified as a different note. • Completely redesigned interface, with a new precision tuning meter. • Improved microphone handling and a louder reference tone, plus automatic recovery after calls. • Clearer Pro section: see exactly what the free version includes and what Pro unlocks. • Fixed a freeze when selecting a Pro tuning.
