Easily Tune Your Ukulele

The free ukulele tuner found in the GuitarTuna app is incredibly flexible, and it has two easy-to-use modes that will get you tuned up in no time. With the manual mode you’ll see a uke headstock on your smartphone screen, with each of the four tuning pegs identified with the ‘right’ note for the particular tuning that you may be using. All you have to do is press one of the keys to get a tone (and yes…it even sounds like a uke!) that is exactly at the right pitch. Our manual mode is great because not only will you tune up, you’ll be developing your ear at the same time – an incredibly important skill that players of all levels should possess.

With a simple toggle on the screen you can change into Auto mode. Here our powerful algorithm takes over and determines the exact note that you are trying to tune. An indicator then shows if you are sharp (higher pitch) or flat (lower pitch), which can be quickly adjusted with a simple turn of your uke’s tuning pegs.

Yes – tuning your uke really IS that easy!

Free Tuning App for your Ukulele

Ukuleles are incredibly fun instruments, and being able to play one is a sure bet to entertain a crowd. Ukes are small enough to take just about anywhere, but there’s nothing worse than playing a uke that is out of tune. Our free uke tuner app is just what the doctor ordered!

There’s no need to go out and buy an expensive tuner; you can have an amazingly accurate tuner at your fingertips at absolutely no cost to you! On top of that, we even give you a metronome and an extensive library of ukulele chords to practice with – it’s almost like having your own personal ukulele teacher giving you free lessons!

Ukulele Tuning App Quality

If you have ever used some of the other ukulele tuner apps that are available, you may have noticed that they just are really hard to use with any level of consistency. We’ve seen some tuning apps where the tuning indicator just bounces all over the place, and it’s almost impossible to tell if you are truly tuned to pitch. That’s because the technology behind the apps simply isn’t robust enough.

With our free uke tuner app, it’s powered by the same advanced audio algorithm that you’ll find in the widely respected Yousician app. There’s no instrument cables needed – all you need is the mic on your phone! From there the internal tuner engine takes over and gives you a stable and reliable tuning platform where you’ll never have to worry that your tuning isn’t going to be accurate.

Alternate Tunings for the Ukulele

One huge benefit of our ukulele tuner is the support for alternate tunings. Just as with the guitar, experimenting with tunings that aren’t the standard can help to create a burst of creativity. Each type of tuning has its own characteristics that gives your playing it’s personality.

We’ve got you covered! All it takes with our uke tuning app is to go into the Settings and you’ll find a wide range of tunings to explore, all the way from the ‘standard’ tuning (G, C, E, A) to the popular slack key found in traditional Hawaiian music (G, C, E, G).

We’re confident that the combination of accuracy, tuning options, and other additional features in our ukulele tuner app is hard to beat. Download the GuitarTuna app for free today!
