The #1 tuner in the world!
This is not just a guitar tuner: we’ve got +100 tunings for 15 instruments! It’s fast, accurate and easy to use. GuitarTuna has been downloaded over 80 million times, which makes it the most downloaded tuning app in the world.

Tuna has it all:
• A LOT of tunings: standard, drop D, drop A, half step down and loads more
• Metronome with tap-for-tempo and multiple time signatures
• Chromatic tuner for alternative tunings and for tuning any instrument
• The clean, intuitive and customisable UI makes it easy for anyone to use
• Tools: Ear training, chord guide, games, and exercises.

How it works:
Just pluck a string on your instrument - Tuna detects the sound using your device’s microphone. You’ll get instant visual feedback while tuning. No cables needed.
With our award-winning audio recognition technology, we guarantee you an insanely accurate tuning result. We use noise cancellation technology to eliminate background noises while you tune.

We’ve put a lot of love and effort into making GuitarTuna the tuner it is today. User feedback is valuable to us, and you can be sure we’re listening. We recently added chromatic tuner to the app because of the sheer amount of requests for it. With the chromatic tuner, users can create their own tunings or tune basically any instrument (you can even identify your landline’s beeping frequency).

It’s pretty cool you actually read this far! Here’s a joke for you: What’s the difference between a bass and a tuna? You can tuna bass, but you can’t bass a tuna.
Now download the app and see how it is.
