A precise chromatic guitar tuner that is easy to use! Just make the two dots overlap and you are good to go!

The tuner works in landscape and portrait, iPhone and iPad! Note that on iPad the mic is not at the bottom where the speakers are - it is at the top! Hold the mic close to the source if it is silent like an unplugged electric guitar.

As a bonus you can change the base frequency for the tuning from 440Hz to something else, if it fits your voice or instrument better. It is also a great way to drive your bandmates crazy :)

Really great

This is like my first time ever actually reviewing a app but I gotta say after using guitar tuna for years I got sick of them trying to worm cash out of me for any tuning other than standard. And as someone who plays a lot of Drop tunings, along with my 7 and 8 string I couldn’t find an app that was free and actually accurate, until I found the LunaTuna, really this app is a great tuner and I’ve been using it exclusively since. No hoops or anything to jump through just a basic accurate tuning app which is just what I needed. Really great app, easy to use, accurate, versatile I couldn’t ask for anything else! 10/10! Keep it up!

Thank‘s so much for the great rating! That was actually the reason for making the app, I think a tuner should not be a subscription that is more than buying a real tuner every two weeks ☺️ Happy shredding 🤘

The app is clear in its purpose and doesn’t stray off into useless functions or irrelevant advertisements. I like the display of specific frequency as well. The developer was also very responsive in solving some of the issues I was having with misread overtones in the app. Thank you, sincerely

Beautiful and Simple Tuning App

If you’re looking for the perfect tuning app, this is it. Does exactly what it needs to and nothing more, tiny download, dead simple to use, doesn’t waste resources, yet manages to be beautiful. Minimal, elegant, and usable all at the same time.
