GuitarTuna is offered by Yousician, a learning service for guitarists. This is one of the more complicated offerings available for tuning, but it does come with plenty of learning resources. It is especially handy for beginners.

Tuning stability is accurate, as you would hope with a tuner. You also have the means to learn songs with chord sheets and tablature readily available. GuitarTuna also comes with a metronome. It is as much a learning resource as it is a means to make sure you’re in tune.

Best for Alternate Tunings: Fender Guitar Tuner

Fender needs no introduction for guitarists. You’ve likely heard of the Stratocaster, arguably the most famous guitar in the history of the instrument. The Fender Guitar Tuner is built for the whole guitar family, with guitars, bass, and ukeleles all supported.

Tuning is extremely precise, with hard note values and cents provided for each string. You have quite a few tuning options, as well. Open, chromatic, and drop tunings are all readily available. The interface itself is clear and easy to use, with zero ads.

Best for Simplicity: Pano Tuner

Pano Tuner is an option for users who don’t need much out of their tuning apps. It has a single function, and that’s to provide chromatic tuning. Pano Tuner does assume you know the tuning of your instrument, or rather the ideal tuning.

It doesn’t have support for alternate tunings, so you’ll have to provide those yourself. Where it excels is in being a no-frills app. In addition to letters for the note names, you can also use solfège, or the Do Re Mi convention.

It is a quick and easy tuner.Some bare guidelines for tuning specific instruments would be a welcome addition.
The interface is clear and simple.There are no numeric readings for the cent values of a given note.

Best for Old Gear Buffs: BOSS Tuner

BOSS Tuner is a great choice for guitarists accustomed to using pedal tuners.


BOSS, a subsidiary of Roland, has been a respected name in guitar pedals for decades. This app serves as a virtual version of its Chromatic Tuner TU-3 pedal. The interface itself is highly evocative of the pedal, complete with the red or blue LEDs showing the note name.

Using the BOSS Tuner is fairly straightforward, so it makes for one of the best guitar tuner apps. You pluck your string and try to get the instrument in tune by getting the green light up to the top to hit the 0 mark on a chosen note. BOSS Tuner comes with support for guitar, bass, ukulele, violin, cello, brass, and much more.

It provides fairly precise tuning.The app can be a bit daunting if you’ve never used a pedal tuner before.

You can use it as a simple chromatic tuner, which is perfectly fine. However, you can also opt for using reference pitches to tune your instrument. gStrings is a general-use tuner, so you can use it with any instrument.

What makes this one of the best guitar tuner apps is just the simplicity of it as a whole. You aren’t going to stumble through multiple menus just to get where you want to tune an instrument. Instead, it is a quick and tidy process.

CarlTune is another basic tuning app. It has a somewhat more in-depth interface despite offering basic chromatic tuning. What marks CarlTune apart is the interface, which goes so far as to provide note names and their location on the staff.

CarlTune’s analog clock interface can be a bit trying for beginners to use. However, once you get down to it, the app is highly accurate in terms of pitch accuracy. This may be one of the best guitar tuner apps, but it is usable by players of all pitched instruments.

Best for Ease of Use: Fine Tuner

Fine Tuner looks to offer a fairly basic chromatic tuning experience. That said, the simple and clear interface also has quite a bit of functionality to it. What makes this one of the best guitar tuner apps is the great accuracy and precise Hertz values for each note you play.

Fine Tuner does have support for alternate tunings and learning resources. However, you’ll need to ready yourself for a nominal fee to unlock additional tunings. That aside, it is a great tuner for just basic functionality.

The simple interface leaves everything easily seen on a single screen.Unlocking alternate tunings requires an IAP.

Best for Vintage Inspiration: Cleartune

Cleartune rounds out this list and is yet another great guitar tuner app. Cleartune has an interface more evocative of old analog studio equipment. Note values are provided in cents, so you can easily see if a note is too sharp or flat.

Cleartune also comes with pitch pipes, so you can go off perfect reference tones to get your tuning up to par. There are a few drawbacks, namely that it is a paid app instead of the free offerings seen on most of this list. That aside, it is a great choice if you’re looking for something with a vintage interface.

What to Know About Choosing the Best Guitar Tuner App

Not all guitar tuners are made equal. This is something that has plagued guitarists for decades as even a well-regarded guitar tuner can be prone to inaccurate readings. As such, there are a few considerations to keep in mind when choosing your guitar tuner app of choice.


Note accuracy is paramount with guitar tuners for a variety of reasons. If you’re learning songs, you’re typically tuning to the same tunings as your favorite artists.

If the tuner isn’t calibrated correctly or inaccurately, you won’t be matching up to the recording when it comes time to practice. You want an accurate tuner, but thankfully the ones provided on this list are all perfectly suitable for guitar usage.


The interface of your tuner is another important consideration. In the past, you didn’t really have a say in what sort of interface a tuner might have. You’d simply just purchase one that provided accurate readings or you would improve your relative pitch over years of playing.

Thankfully, those days are in the past, as you have the option for modern and vintage-inspired interfaces. Really, which one is better will come down to personal preference. Modern interfaces have the benefit of providing clear and concise information.

Microphone and Line In Support

Most acoustic players will likely opt for their smartphone’s built-in microphone for tuning purposes. Given how clear and present the sound of acoustic is, this is certainly a worthwhile use. If you’re primarily an electric player, you’ll want an app with a line in support.

Both the iPhone and Android have options for hooking up electric guitars and basses to your smartphone. It might be an additional expense, but it certainly beats trying to make sure your surroundings are quiet enough to actually capture the sound of your unplugged electric guitar.

Using the Best Guitar Tuner Apps: What It’s Like

Using a guitar tuner app is like using an old-fashioned tuner but with a few additional perks. For starters, you’re likely carrying your smartphone or tablet with you to most locations. This means you’re carrying less gear, which leaves room for more useful things like cables, picks, and other accessories.

Guitar tuner apps are quick to use and generally don’t require much aside from a bit of your attention to get the instrument in tune. Of the many advantages of smartphones, this is one of the strongest benefits for musicians.
