GREAT, but I still have some ideas
Kira.crystal on 9/25/2017
Read a different review if you want to know all the good the bugs about this app because they cover them all. I just wanted to make a suggestion. It is already so, so useful, but it would be even more useful if there was an option to play the learning games without a time limit so that the user could just practice accuracy if they are not ready for accuracy AND speed yet. A feature that tells you what chord/note you are playing would also be helpful if you want to play a chord/note and then check if it is what you meant to play.
Joselmj on 9/25/2017
Tunes my guitar. That's all I use it for, and it does it well.
Love the apps
PharmarZan on 9/24/2017
Thank you for this snazzy app.
Keitofrank on 9/24/2017
it’s great just i don’t wanna pay money for the other tunings
Does What it Says on the Tin
MinecraftScrolls47 on 9/24/2017
It's functional, versatil, and useful-- especially the tuner portion of the app. However, only one lesson is not behind a paywall. So if you are looking to learn guitar, look somewhere else.
Great app
ElChicoLopez on 9/24/2017
I use the app almost every time I learn a song or tune a guitar, fantastic great job
Jonathan222001 on 9/24/2017

Guitar Tuna
Grayblue47 on 9/21/2017
I'm embarrassed to say how many guitar apps I have on my phone, but this is the one I use. Perfect simplicity.
This is inaccurate
Raven Fether on 9/21/2017
My guitar sounds terrible with this tuner! You should go find a better one.
Great and Free!!!
rosasv17 on 9/21/2017
Really useful and so easy to use every musician should have this
Best ever
Guitar M&M on 9/21/2017
Best I've ever used - simple, fast, and accurate !
Works great
aj81ds on 9/21/2017
I play in E & D Standard and this app works great for both acoustic & electric guitar.
Very functional
gtucker1984 on 9/21/2017
Since my phone is the most common, wearable technology I have on me at all times, it would only work to my advantage to call up the tuner and have my bass tuned in moments. I highly recommend this as I know "my ear" is not highly trained at the moment as I may forget to pack my other tuner(s). You don't have to get ready… If you stay ready…
Best thing ever for beginners
Levardicus on 9/21/2017
This tuner is so helpful for beginners because it has all of the chords and a metronome for them to practice with. Not to mention the tuner is great as well!
Allday70 on 9/20/2017
Love this app!
Excellent for those that are new to Guitar
Ollie213 on 9/20/2017
Very easy to use and I feel like a pro tuning my guitar. If learning chords were as easy as using this app I might already be on tour!!!
Fast and Easy
benharrell_19 on 9/20/2017
This app is definitely the easiest tuning app I have used for my guitar. It's honestly touch free, it just listens while you play each note. It also shows you how flat or sharp each note is. Plus, you don't even need to know the notes by name, it does that for you!
Best guitar tuner app
Joshua mtz on 9/20/2017
I love this app it is the easiest thing to use and it's free.
Edgar Leal123 on 9/20/2017
It's a papi app
Best Online Tuner I've Found
Joanbee on 9/20/2017
Sometimes, even though I've ear tuned my guitar, I can tell something is not quite right. Tuner helps me get it right, even if it's just a hair off. I really like this app which simplifies tuning.
It's amazing
Pryncess11 on 9/19/2017
Don't have time to write about how amazing. Just know it's amazing
It's awesome!
DaBoss264 on 9/19/2017
The tuner is spot on, the metronome is amazing, and everything else is amazing too. 10/10! 👍🏻😁🎸💯💯
LoveLiv800 on 9/19/2017
I personally play guitar and I have tried a LOT of tuners. Out of them all I prefer Guitar Tuna. The accuracy is perfect and I love the standard mode. You can also follow a metronome ( you can even adjust the speed ) and you can play along to songs! For free? YES PLEASE!! Please download this app it is so worth it! ROCK ON🎸⚡️
Guitar Tuna

It is awesomeness!!!

Hellavet on 9/19/2017

Best guitar tuner there is!

Great app! on 9/19/2017
Best tuning app! Easy to use.
Tune for songs in half the time
Golfnutty58 on 9/19/2017
Playing guitar is tough when you play songs that change tunings. This app reduced the time and automatically tells you when you got it right... I can change from E, to drop D or G and back to E in half the time now. Really love this app, and that makes it rare in my book.
Better than my actual guitar tuner
Jillybrews on 9/19/2017
Love this app
Kylie.corn on 9/19/2017
It's great for getting eaten out :)
A good application.
chakib15 on 9/19/2017
An easy and useful application.
Pretty okay
fomic on 9/18/2017
My friends and I really like this "Tuna". When your ear fails you this is a great visual of the sound
jesssalesrepoklahomacityOK on 9/18/2017
No joke, this is THE ONLY guitar tuner you need for your acoustic. I don't own an electric so I can't speak on how well that works. But for an acoustic- this is the only tuner you need. ITS THE BEST
You know
PoopCan11 on 9/18/2017
