How to Use
This app helps you tune your guitar by listening to the notes you play and identifying what pitch it hears. 1. Allow microphone access when prompted by your browser 2. Play a single note on your guitar near your device's microphone 3. The app will display the detected note name and frequency in Hz 4. If the note shows "sharp," tune the string down (loosen) 5. If the note shows "flat," tune the string up (tighten) 6. Keep adjusting until you see just the note name without "sharp" or "flat" 7. Use the "start/stop an E note" button to play a reference E note through your speakers for comparison The app continuously listens and updates the display in real-time. For best results, play single notes clearly and avoid background noise. Standard guitar tuning from lowest to highest string is E-A-D-G-B-E.
