Really helpful
Pattttreek on 6/20/2018
If you can’t afford a tuner like me, guitar tuna really helps me out. When I’m at a friends and wanna play his guitar, I can just pull out my phone and tune it. And it really picks up the vibrations, even when not plugged into an amp
It broke my string...
Emma🏐 on 6/19/2018
On the part where you can tune it showed me the wrong string. It showed the E tuner as G so as I was trying to tune it it busted. 😢
Awesome Tuner
KingKai25 on 6/19/2018
I've been using GuitarTuna for a couple years now, and it's never let me down. :-) Thanks for a great app!
Accurate, easy to use, and fast!
towj10 on 6/19/2018
This app is great for an easy fast tuneup that is very accurate and can be done on the go, my only complaint is that if it is too loud around you it will not pick up the noise of your guitar and will pick up the noise around you making it seem sharp or flat but other than that it’s spectacular
It’s cool I guess
Hi my name is GAY BOI 78 on 6/19/2018
It’s cool I like it But... Lol I wasn’t going to write anything why did you come all the way do here lol Your still here, For what 🤔 what do you want to see so bad? Dab I wrote dab not to long ago is that what you wanted? It doesn’t matter anyway I’m leaving Thanks for wasting like 2 mins of your time you could have done something very productive 😑
Not bad for what it is
Evadog666 on 6/18/2018
For a tuner that doesn’t sense vibrations and rely solely on the microphone, it is very accurate. My only problem with the app is that you have to pay to use alternate tunings.
Just better
Nfigh on 6/18/2018
Just so much better than any other tuner app (or piece of hardware) that I’ve seen
Highly Recommend
AztecaBabie16 on 6/18/2018
I recommend this one because it’s accurate and easy to read.
lilly0808👅 on 6/18/2018

First time game changer
Dj10869 on 6/17/2018
I’m just starting to learn and having a tuner on your phone makes the whole process so much easier.
My go to tuning app on 6/17/2018
Easy and fast to use
Does the trick!
Emmferd on 6/17/2018
Works great. I like how it tells you how far you are from the note so it helps you visualize how to tune the instrument.
I just tuned my dad’s banjo!
Drewbie D, The Referee! on 6/17/2018
It’s been sitting in a case for over 20 years! Tuned it up and getting ready to learn to play it!
Great app, accurate tuning.
eh1736273 on 6/16/2018
I’ve used this app a lot to tune both my electric and acoustic guitar. It’s very simple and lacks the complications behind regular tuners.
Always with Me
Liddybird on 6/16/2018
I never have to worry about where my guitar tuner is. It is easy and accurate.
Best cell phone based tuner

Solid app!!
BilllllllllllllllllLLlYy on 6/14/2018
This app helps me tune for my amazing guitar playing skillz and i really appreciate david (the man who made this app). I’m not really sure if that’s his name for sure but the guy that would make an app like this seems like he would be a david. Good work david!!!!!!
Great App
tgome208 on 6/14/2018

This is a great app tuner.
Heyimjimmorrison on 6/13/2018
I’ve been playing guitar for 16 years, and have used a handful of free tuning apps, and this is my favorite.
Anyone can! So easy
Maltafaz on 6/13/2018
Had no idea one could tune a guitar “online”. So easy and even I could do it....that means anyone can tune a guitar. Tuning a guitar was always tough for me...not anymore thanks to Guitar Tuna
Dude this is the one.
private_reserve on 6/13/2018
You’re search for the perfect mobile guitar tuner is over my friend. This ... is the one. 💯💯🤙🏽
Great tuner
Original PBR Man on 6/13/2018
This tuner is quick and easy to use. It has both visual and audible cues to let you know when your string is perfectly in tune. With the free version, you can select from different tunings: guitar, bass, ukulele and cavaquinho. It includes a metronome with many different counts (4/4, 5/4, 7/4, etc), and a chord library. There are also some games, but I haven’t played any of them. You will need to upgrade (pay $) to get alternative/ custom tunings. With the upgrade you get tunings for guitar, bass, ukulele and cavaquinho, as well as 7 and 12 string guitar, 5 string bass, violin family and folk instruments. I only have the free version so I can’t review the upgrade.
The best
will the butcher on 6/13/2018
Great app . Easy to use . And accurate
Thanks for adding uke chords!
JocelynPrice on 6/12/2018
Great app. I requested that they add ukulele chords, and they have done just that. Worth every penny.
TuckerHG on 6/12/2018
I was skeptical that a guitar tuner app would work. Post little brother meddling my guitar sounded bad and the only tuner I have access to is my cousin’s and we don’t see each other a lot. This guitar tuner works great and saved me $15.00.
Simple yet effective app to tune your guitar
BBrad3333 on 6/12/2018
Super easy!!!
Cats r weird on 6/12/2018
I play the ukulele and have no clue how to tune it without this app. Perfect if you don’t want to go out and buy a tuner.
Easy to use
Body Mind Spirit on 6/12/2018
No extra gear to haul around, no cords. All you need is a charged phone! Great app!
Lou Anthony on 6/12/2018
I think this should be a mandatory app on your phone it is amazing chord lessons and tuner. Thank you for this
Nice tuner
Journaling novice on 6/11/2018
Great for tuning. This is the only tuner that actually works for me.
It works.
KingKuntaJay on 6/11/2018
Looking for just a quick and efficient tuner? This is the app. It works. Don't expect more or less.
Blake McGill on 6/11/2018
I'll keep it simple very good very easy to use and reliable
Do not install
Bryceeeeeeeeeeeee on 6/11/2018
This app is terrible and you need to pay for things like games and tunings
This is a really good app😍😍😍😍😍😁😁😁😁
rylee kitty play on 6/10/2018
This app is so accurate and is fun to because it has games you can play with your guitar😊😊😍😍😍
A very good tuner
Passwordstaken on 6/10/2018
This app helps me a lot not only with tuning but with switching from cords I'm also teaching my little cousin and this app helps a lot. highly recommend!
Great for tuning
Richpee200 on 6/9/2018
That's all I use it for but I love it -- one fewer accessory I have to keep track of.
Might as well invest in a real tuner if you drop tune at all
whytftoineedanicknametosubmit on 6/9/2018
Outrageously priced just to get anything other than standard
Does not work
JSlay707 on 6/9/2018
When ever I tune it I put on my device that clips on to the head and, it showed it majorly of-tune.
Can’t find how to change tuning
Camalammadingdong on 6/9/2018
