I like Guitar Tuna but my teacher claims all timers are not accurate. I don’t believe him. It’s the fastest and most dependable way to tune a guitar. Thanks.

Simplest tuner I’ve used.

One of the best UIs I’ve experienced from any app.
Just stopped working.
jflewton on 4/19/2018
For whatever reason, this app worked fine, then just stopped. Don’t waste your time.
This works
Mythicbman on 4/19/2018
I’ve been using this app for five years. Thought I owed a five star review by now. No problems/crashes. Download it, get your tuner. You won’t need another one.

Worked great but for some reason when I switched phones all I paid for is gone. I’m using the same iTunes account and everything.
Great App!

Really helps me learn to turn my guitar. I’m loving this app so far after my dad showed it to me.👌🏾
Incredibly helpful
Tucana sumana on 4/15/2018
I’m just picking up guitar and this app has made the learning process a lot easier
It is great!😋
Bro Harry D on 4/15/2018
I love this app cause I can use it for my guitar and ukulele! And since it’s for two things on one app, I don’t have to have two apps, one for my ukulele and guitar. Instead, I use less storage cause I can use it for both on this one app! Over all, I think everyone with a guitar,ukulele,etc should get this amazing tuner app!
Good app, one suggestion
mdenison7 on 4/15/2018
Great app, I use the free version to tune my guitar and look up chords. I’m a self-taught beginner at guitar and ukulele, so this app is really wonderful for me. I love that it now includes a uke and bass tuner! For free! 😄 The only thing I would change is the chord library scroll: if it had a continuous scroll that’d be great (it’s a hassle to look up a C chord, swipe all the way to the B chords at the other end, and then scroll all the way back to the C chords). It would be great if it were a continuous round. Other than that I’d give it 5 stars. 🌟
Dr. Amendoim on 4/15/2018
I have no clue at all how to tune a guitar... Somehow my guitar is perfectly tuned with this app. Thank you!
Best tuner app!
jake brien! on 4/15/2018
This is the best guitar tuner out there I highly recommend this to every guitar player, have my friends hooked to this app. ..thank you GUITAR TUNA!!
Very consistent

I like the app because it's very helpful as a Lerner
One of the more useful apps
EdwardSelph on 4/15/2018
Pretty good guitar tuner. Lot of options. Been able to tune a 12 string, banjo, guitar, uke in a pinch when I don't have a clip on handy.
Enter_A_Nickname6969 on 4/14/2018
I’ve recently started learning how to play guitar and this app was the perfect accompaniment for me, it gives you chords, a metronome, and lets you tune your guitar all at once, I don’t have to worry about going out and buying all sorts of extra stuff on top of my guitar and my 100$/month lessons, great job guys!!!
Great App
drummer52 on 4/14/2018
I sat down and tuned my guitars using the app and a Snark vibration tuner and the results were nearly identical. I now have a lot of trust in this app.
Works great
Andrewman97 on 4/14/2018
Love this app, use it every time I need to tune my guitar.
My string snapped!!!
Fireguy1234 on 4/14/2018
I was trying to tune my E string on my guitar and it kept telling me that I was too low, kept tightening and the string snapped!!! It wasn’t too low, probably too high at the point!!
Secret weapon
Bggggeeeedd on 4/14/2018
I downloaded this app thinking it was just a standard guitar tuner. I used it for about 6 months just as a tuner. I needed to tune a 12 string acoustic for my dad and didn't have a 12 string tuner. I did a little exploring in this app and low and behold I found it actually has a setting just for 12 strings! It cut the time of tuning from ear to doing it off the app from 10 minutes + by ear to barely any time with using the app. So as I realized I hadn't takin advantage of the app as much as I should I started exploring even more. It's a gold mine of knowledge. Not only is it a tuner (best app tuner I've used personally) but it also has a metronome , games , chords, a plethora of instruments to choose from and it's SUPER easy to navigate. I got my dad an iPhone (first iPhone he's 65) and he always complained about how it was hard to use. I showed him the GuitarTuna app and he hasn't ever had any confusion with how to use it. I think that says a lot of how instinctive the user interface is if my dad can do it :P all in all I can't recommend this app enough. I literally tell all my guitar player friends to try it and not one has said anything negative about it. I love it! I can't imagine how the developers can make it better than it already is but something tells me they will! Thanks for making an awesome app. From one musician to another, THANKS!!! Cheers! -Brad.

Works great for my uke, recommended
Tone deaf maybe?
Tyler8675309 on 4/14/2018
Your app break for too often and can’t seem to figure out how a guitar should actually sound. Used to work pretty well but whatever happened ruined this app.
Great App
texxtex on 4/14/2018
I use this app across multiple instruments, and the different tunings offered have helped me with accompanying my harmonicas in much more fluidly.
Does the job but.....
Malblackness on 4/13/2018
I noticed that the access to the microphone also seems to activate the hands free calling when opened in the car. Definitely didn’t give it access to that so it seems a lil suspect to me.(i tune in the car before I play outside)
itsKody42 on 4/13/2018
My guitar sounds perfect!!!
Great tuner for free!
Matthew stevens is awaome on 4/13/2018
Really good tuner for it being free, a lot of the bad reviews talk about having to tune so high the string breaks or that it won’t move, make sure you aren’t in manual mode on the wrong string. Also, use a little sense and don’t tighten too much obviously. Overall I recommend using this tuner.
Simple and good!
Lulis56 on 4/13/2018
Perfect app. It’s simple and efficient! Does what it’s supposed to do and so easy to use. Open it, strum a string, and it tells you if it’s too high or too low. You tune, and voila, when you hit the sweet spot it lets you know!
Meookiee on 4/11/2018
it’s great
Match to presets
fireside08 on 4/11/2018
Great for standard tunings. Shows you whether your on or off tune. Doesn’t tell you what nite your playing, just how far you are from a standard tuning. For that reason, not really useful for non-standard timings and not good for ear training.
I really like this app
v-lonely-boi on 4/10/2018
I use this app to tune my ukulele and guitar. There are three different settings to tune guitar, ukulele, and bass in standard tuning. The app is simple and easy for beginners (like me) to follow. I highly recommend this app. (I only use it as a tuner, and occasionally for chords)
Great device
Ty grigs on 4/10/2018
Wonderful, useful app
You have to pay for Mandolin tuning.
Ignaeus Trollbane on 4/10/2018
I only tried to use this for a mandolin and you have to pay for it. Nope!
1234gg$&t😍 on 4/10/2018
I’ve had a guitar sitting in my room forever from when my sister used to play and I’ve always wanted to start, but I had never really tried because it was always out of tune. I tried tuning it myself and it always sounded off, this app helped so much and I’m going to try to start playing!!!!!
Amir and alireza on 4/10/2018
thanks 🙏🏻❤️
Versatile, easy, fast
Fiddlin' Cid H. on 4/9/2018
And so long as I didn’t sign away the rights to my firstborn child usually make it, I love it! Use for violin and guitar
It does exactly what you expect perfectly
dane's x51 on 4/8/2018
Could not wish for a better tuner
GuoyRacest on 4/8/2018
No matter what guitar I use GuitarTuna always gets it perfectly tuned. Never had a problem with the app. There are games and stuff but to be honest I’ve never really clicked on the games tab. Very unconfusing menu
Works very well
SevinStorey on 4/8/2018
As a young boy (in my early 20’s) I picked up my first hand me down flat top and bought a chord chart poster from Walmart and self taught myself how to strum chords enough to eventually start playing parties and small bars. I never did learn how to tune however but I can definitely tell when she’s out. I would always have to ask a friend or count on a small tuner that was easy to misplace or lose but now I can do it on my phone which I always have in my pocket and its extremely accurate as I’ve checked it on tuners and with class act guitar players including myself. There’s no bothersome pop ups (thank God) and it never asks me to buy anything,(again thank God) or I would drop it from my phone. Great deal for anybody out there.
absolutely amazing
leahfisher on 4/8/2018
this app works perfectly for me to tune my ukulele, it is the best one i have used by far!!
