Guitar tuner app designed for the visually impaired. Provides real-time live haptic feedback to indicate proximity to correct note.
How to use:
Open app. Ensure silent mode on device is OFF. Allow device to access microphone.
Start playing note.
When current note is flat, vibration will be harsh (similar to a "buzz"). Tune up to the desired note.
When current note is sharp, vibration will be soft (similar to a "hum"). Tune down to the desired note.
Vibration should become more frequent as you get closer to the target note.
When fully in tune, vibration will stop and an audible chime will be heard.
Repeat the above on the other strings until all strings are in tune.
For best results, rest your phone directly on the side of guitar while playing. The body of the guitar will amplify the vibrations.
