## What is Overtone?

Overtone is a guitar tuner that gets out of your way. Open it and it's already listening — no buttons, no
  setup. Pluck a string and the big, easy-to-read display tells you exactly where you are and which way to
  turn.

  PRECISE, RESPONSIVE TUNING
  • Real-time pitch detection that locks on fast and reads steady
  • Auto string detection — it knows whether you're on the low E or the high one, so you can just play
  • Clear cents readout with flat / in-tune / sharp guidance and a satisfying nudge when you land it
  • Standard tuning (E A D G B E), A4 = 440 Hz
  • Lock to a single string when you want to stay put

  SCALES & FRETBOARD MAPS
  More than a tuner — a pocket reference for finding your sound:
  • Scales grouped by feel across blues, folk, soul, and reggae
  • Tap any scale to see it laid out on the fretboard
  • Transpose to any root to match the song you're playing
  • Save the scales you reach for most to your favorites

  PLAY ALONG IN REAL TIME
  Turn practice into a game your ears can see:
  • Pick a scale and start playing — the board lights up the exact note you're hitting, live
  • Watch your runs come alive on the fretboard as you move
  • A new way to learn a scale, find the next note, and stay in key

  BUILT TO LOOK AT
  A vintage, hand-tuned aesthetic — warm amber on deep black, serif numerals, and a subtle film grain —
  that feels like a piece of studio gear, not a utility app. The screen stays awake while you tune so
  you're never reaching for your phone mid-string.

  No accounts. No clutter. Just pick it up and play in tune.
