Doesn’t it seem like most of the apps and tools available nowadays always seem to be only for guitars and guitar players? Have you ever searched for a free online ukulele tuner app but just haven’t struck gold?

Tuning a ukulele with GuitarTuna

The digital ukulele tuner in the GuitarTuna app may be just what you’ve been looking for. Having an incredible tuning app on your smartphone is one thing, but our uke tuner also boasts additional features that help you level up your ukulele playing skills. It doesn’t matter if you are a seasoned pro or just starting out, our uke tuning app is the right tool at the right time.

Ukulele Tunings


The free ukulele tuner in the GuitarTuna app is incredibly flexible and has two easy-to-use modes that’ll 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 your chosen tuning. All you have to do is press one of the keys to get a tone that is exactly at the right pitch. The app’s manual mode is great because while you tune your ukulele, you get to train your ear at the same time. This is an incredibly important skill that players of all levels benefit from.

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 the tuning pegs of your uke.

Yes – tuning your uke really is that easy. And the best thing of all, our online tuner app is completely free to use.

Ukulele Tuning App Quality

Have you ever used any of the other tuner apps or a separate tuner device to tune your ukulele? Getting your instrument in tune with some of these tools can sometimes be difficult as the feedback you get isn’t always accurate or reliable enough.

Our free uke tuner app is powered by the same advanced audio algorithm that you’ll find in the Yousician app. You don’t need any instrument cables to get your uke in tune—the mic on your phone is all you need. From there the internal tuner engine takes over and gives you a stable and reliable tuning platform. 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, in addition to the standard tuning. Just as with the guitar, experimenting with tunings that aren’t the standard G C E A tuning of the ukulele can inspire you with a burst of creativity. Each type of tuning has its own characteristics that give your playing its unique personality.

All it takes with our uke tuning app is to go into the Settings. You’ll find a wide range of ukulele 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 to tune your ukulele.
