## What is CGDA Tuner?

CGDA Tuner is a fast, friendly tuner built for string players. Play a string and the whole screen responds — green means you're in tune, warm colours mean you're sharp or flat. No cluttered dials, no guesswork.

NINE MODES, ONE TUNER
- Violin, Viola, Cello, Double Bass
- Guitar, Bass Guitar, Ukulele, Mandolin
- Chromatic mode for everything else

CLEAR, GLANCEABLE FEEDBACK
- Full-screen colour that turns green when you're in tune
- Note name, frequency (Hz), and cent offset at a glance
- Fine-grained meter for landing exactly on pitch
- Over-tension warning helps protect your strings

TUNE BY EAR, TOO
- Play a sustained reference tone for any string and match it — just like tuning to a piano

ALTERNATE TUNINGS
- Guitar: Drop D, DADGAD, Drop C, Open G, Open D, Half-Step Down
- Bass Guitar: Drop D, Half-Step Down
- Ukulele: standard high-G and low-G
- Your last tuning is remembered for each instrument
- Proper flat spelling (E flat, A flat …) where it belongs

MADE FOR PRACTICE
- Starts instantly and works completely offline
- No account, no sign-up
- All instruments and tunings are free — an optional Pro purchase simply removes ads

Whether you're unpacking your cello before rehearsal or dropping your guitar into DADGAD, CGDA Tuner gets you in tune and back to playing.
