I downloaded multiple tuners! This gutiar tuner was so accurate! It perfectly showed you if you need to tune the string higher or lower. I didn't even have to spend much time 🎼🎸
Great app!

Great app
xivioz on 1/21/2018
Very easy to use interface. As soon as you run the app, it’s ready to tune, and it’s very easy to see when your tuning is too high, too low, or just right!
Very useful
A really dank dude on 1/21/2018

Sashamahmud on 1/20/2018
got a ukulele yesterday, had no idea how to tune. THIS. APP. HELPS. SO. MUCH.
Great for beginners!
Samkittygirl on 1/20/2018
I only started playing the guitar a week or so ago. This tuner is incredibly easy to navigate and understand. It lets you know which notes have been tuned already and apparently has games that can help you with intonation. I would highly recommend this app.
Better than the tuner that came with my guitar
Hav0kk on 1/20/2018
This has very accurate tunings, and a large variety of them to suit any genre, if your a guitarist, get this app
Best tuner ever!!!!
Dank Meme Supplier on 1/20/2018
It is right on I love this app
niteshade123 on 1/19/2018
I got a epiphany sg special and I started to tune it using the tuner on the app worked well until the b string when it said it was too low then tightening the string it broke I was really upset and not happy with the app instead I will use a snark 2 I hate the app
Nice app definitely recommended

Hello everyone reading this. This is an app that made my life so much easier. I started playing guitar 4 months ago and I didn’t know anything about the guitar. So I needed someone to tune my guitar for me or at least help me (My grandpa knows how to play and tune guitar. He was pretty young when he started playing on it. But I can’t always ask him to help me). So this app was just perfect for me. It’s free. It shows you all the chords. It’s precise while tuning. And it has little mini-games as well (although if you want more games you need to pay. But it’s pretty reasonable price). So the bottom line than. If you want the basics of the basics on guitar this is the app that will provide you with anything. If you want to learn more you need to pay (But I think their Yousician app is much better if you wanna “master” the guitar). And the best thing is that the app is beautiful, it has a good tuner and all the chords you will probably ever need. (This was kinda too big of a bottom line 🤣) Thank you for reading!
De Lujo!!

That’s my story
Isa Ford on 1/18/2018
This is so amazing. I used to have to go get my ukulele tuned up the ukulele story. But now I can go on GuitarTuna and it is so easy to tune now.
EveryNicknameIsChosen,WhatEven on 1/18/2018
Super convenient, great app. Just picked up a new guitar today & it's tuned nicely with this app
Everything any guitar player needs
Capslockrok3r on 1/18/2018
This app has been a nothing less of a necessity ever since i’ve downloaded it. Easy tuning, lessons, just about everything needed to keep guitars players of any caliber busy in the best of ways.
Great app
Ahdienwkdn on 1/18/2018
Works well on the fly
i did this to get the snail on 1/17/2018
Amazing app loved you can tune any Ripe of guitar easily would highly recommend
Green app
Pipip67 on 1/17/2018
Great app. Other than my smoke detectors, my guitar tuners were the last devices in my house that needed 9 volt batteries. This app has made my house that much greener.
Saucestin on 1/17/2018
I would be lost without this app. My normal tuners that I paid good money for are constantly going through batteries and are also sometimes questionable as to wether they are accurate or not. This app however is dead on every time, can tune a variety of instruments and is always ready to go when I need it. Thanks for making such a great app!
Great free app!
rustyshank on 1/17/2018
Very good for what it is! Would recommend! 👌
Changed for the worst..
Vacuumboots79 on 1/17/2018
Been playing the guitar for 15 years. They use to have a workout section that worked great. They “upgraded” and completely ruined the app with useless crappy songs no one wants to learn or you could learn way easier on youtube. Absolute crap...
Actually works
Johaudgdn on 1/17/2018
I’ve had guitar tuners that you buy at guitar center and all you need is this brah. Get it
Great to have tuner with me always
Willow1958! on 1/17/2018
Easy to use but very accurate and well thought out design.
Jake_theGr8 on 1/17/2018
Amazing always works great
Great app!
Zydacko on 1/16/2018
I always had a heck of a time with drop tuning and getting my 12 string up to snuff. This app has made it a breeze.
"mislu" on 1/16/2018
I love guitar tuna! I use it to tune my mandolin in the mandolin setting. Also when my girls come down to play music they use it to tune their guitars.. I give it a five star rating. I use to get my son to tune everything since he tunes by ear so now I don’t have to wait for him to come home.. It’s perfect for me ..Thank you for making it available. “mislu”
Awesome app!
Tdog.12 on 1/16/2018
I I’m brand new to guitars and finally got my first one, nothing was helping me tune it. I couldn’t figure it out by ear, and didn’t own a tuner. I soon FaceTimed my aunt who had previously owned this guitar and she recommended this app. I finally got my guitar in tune, and it was very easy!!
Cool free app
Mlib069 on 1/16/2018
Super easy to use, and very accurate! Never had a problem with it
iwicha on 1/16/2018
Rad 🤘🏽 I don't use any other tuner
It's work
Зоман on 1/16/2018
good for basic tuning
travis joe on 1/16/2018
Easy to use auto setting. would be nice to have access to at least one free alternative tuning like "drop D".
So great
@nt@gon1$T on 1/15/2018
There is no reason to not like this app
Gets me practicing every day
LLC6307 on 1/15/2018
Great app!
sirgrexter on 1/15/2018
If it wasn’t for the fact that I have to find the Apple charging cord every time I want to do it practically I like it better than dedicated to her about for my Taylor guitar
Cross platform licensing support needed
tacosaremyfood on 1/15/2018
This is a great app, but it should absolutely be possible to share a $13 license between iPhone and Android devices.
Can’t complain.
Abbyouth89 on 1/14/2018
Does its job and does it well.
