How to use

  1. Press "Start tuner" and allow the microphone.
  2. Pluck one string at a time to see the nearest note and the needle.
  3. Turn the tuning peg until the needle is centered (0 cents) and turns green.

Standard tuning

  • Guitar: from the 6th string, E2 · A2 · D3 · G3 · B3 · E4
  • Ukulele: G4 · C4 · E4 · A4
  • Bass: E1 · A1 · D2 · G2

It's most accurate in a quiet place, watching while the note rings after one pluck. Reference pitch is A4 = 440Hz.
