# guitar-tuner-accel

**[Hacker News](https://daily.dev/sources/hn)** · 1 min read · 0 upvotes · 0 comments

## Summary

A browser-based guitar tuner that uses the phone's accelerometer (IMU) instead of a microphone. Press the phone against the guitar body, pluck a string, and the app reads vibration data across all axes to detect pitch, with alias correction to map to the actual string frequency. Requires motion permission and works best on Android devices with high-rate IMU sensors.
