RastaTune helps guitar players tune standard six-string guitars with clear visual feedback.
Open the app, allow microphone access, and play a string. RastaTune listens for pitch, locks onto the closest standard guitar string, and shows whether the note is flat, sharp, or centered.
Features:
- Automatic detection for Low E, A, D, G, B, and High E
- Real-time frequency and cents readout
- Large color tuning meter with tune up and tune down guidance
- Manual string selection
- Sound effects and animated visual feedback
- On-device audio processing; audio is not recorded
RastaTune is designed for quick practice sessions, string changes, and checking tuning before playing.
Improved microphone pitch detection on iPhone and updated tuning feedback visuals.
