the tuner works great, but every time i tried to test my skill level, i would play the exact note that was on the screen at the time it was supposed to be played and it would say i was doing it wrong. i’ve been playing guitar for 3 years now so i’m pretty sure my “skill level” isn’t zero
Very helpful

I am a teacher and have a guitar club at my school. This is a great tool for students.
yournotme on 11/17/2017
This is the best guitar tuner app ever I’m just starting out and have a Ibanez electric guitar and I didn’t know how to tune it but thanks to this app I do now
Great for beginners!
Jaypicker on 11/17/2017

Easy to use and quick to tune guitar and other string instruments.
It is a decent tuner
FatPat1988 on 11/15/2017
It does what you would expect.
Great App
SethSeth on 11/14/2017
Very intuitive, very useful, very simple and easy to use but with enough complexity on the back end to make it versatile. Perfect.
davehuish on 11/14/2017
This works extremely well. I’ve ditch my actual guitar tuner
plcmentor on 11/14/2017

Ear Training
Zuluvulcan on 11/12/2017
I think this app is helping me to develop an ear for the notes as I use it more and more. This in turn is helping me learn to play by ear
Ma23ma16 on 11/12/2017
Helped me ease into learning as a beginner --with tuning
In standard D tune all chords are wrong.
Chatlanian on 11/11/2017
Change the tune to whole step down and open chords cheat sheet. Observe: chords are wrong, they remain as in standard E tune. This app is a ripoff. I want my $9.99 back
Love this app
Lssccs on 11/11/2017
Great tuner. Really handy to have this app. Works well even with an unplugged electric.
New look. New like.
Proac1 on 11/11/2017
Love the updated version as of 11/11/17. The most accurate tuner I have used.
Randaller on 11/11/2017

Da kine!
Only standard tune less you pay others are free
TAT2JAS on 11/9/2017
I think this app sucked fender has a free app you can tune anyway you like FREE So to pay you for a free service that fender a trusted guitar company for years so paying for this app for any reason seems ignorant and like I don’t like my money
ZCB13 on 11/9/2017
Pretty Great! Use this all the time!
Was better before
AmyC2015 on 11/9/2017
This version kinda messed with my tuner part for a electric guitar. It keeps thinking my B and E string is a G string. Before the update there was no problem and was a perfect app. I also purchased the unlock everything forever package and it’s so worth it. I’ve loved learning with this app. It is the best app out there so far so it’s worth your time. ^•^
Vitas Varnas on 11/8/2017
This app is so good. It's more accurate than most tuners, and has a variety of different options. Plus it's free. What's not to like?
Excellent app
NCshowgirl on 11/8/2017
Love it! Great for beginners :)
Tefft on 11/8/2017
Love how simple this is to use
Tuning is a snap
dwr447 on 11/8/2017
GuitarTuna is very easy to use even if you are a beginner. I doubt that I will ever tune my guitar any other way (unless I lose and can't replace my phone).
It’s okay but...
creeperstorm75 on 11/8/2017
This app is very helpful but once I get to the E string it gets glitchy. If you could fix this I would be very appreciative
Really the best app
Saramazing101 on 11/7/2017
I downloaded every guitar app this one is the best
It’s really easy to use!
reidrich on 11/7/2017
I am a professional musician who uses this to tune my guitar. It’s the best one I’ve found so far.
Best free tuner
Blue God 517 on 11/7/2017

Unbiased8Relevance90Nine on 11/5/2017
This app is great has all of the features that you would need. Always works great in a pinch whether you're a professional or an amateur. P. S. I am not a robot. - Actual Person
Easy, Fast and Accurate
Kokila on 11/5/2017
I’ve been using this app for years and I can honestly say that it is the best app out there. I recommend it to anyone.
Update caused it to stop working
Kujoduke on 11/5/2017
As of the newest update on 11/5/17 it has caused the tuner to not pickup my guitar... And I have purchased tuning for electric guitar but when I changed my phone I had to buy it again
revolvermd on 11/4/2017
This app whole good has turned into a micro transaction type app. I’ve paid for this app already before I got my new phone but it seems I have to pay more money for an app I should already own. Now even more than the original price to unlock all its features since Yousician took over. Another money grab situation. Seems like if you downloaded and payed before it doesn’t matter since they don’t seem to keep record of past purchases.
The worst
Gabester 1031 on 11/4/2017
I was tuning my guitar and the string broke
Helped quite a bit!
AvianaTheJet on 11/4/2017
I really enjoy this app! I have been trying to learn the guitar for quite a while but never could remember the chords. Now with the pictures and help of this app I am learning all new chords!👌🏻👌🏻
Bad for anything but gutair
Will Clickner on 11/4/2017
When I go on to tune my bass it never works it says my bass is way below tune when it is not PLEASE FIX !!
Love it
Lockstar1713 on 11/4/2017
Their is really no reason to go spend money on a shark or anything, you take your phone with you everywhere you go and I’ve used it to tune my guitar as well as when I go over to other people’s houses and their pickin stick is out of tune. I’ve also used it to tune mandolins, banjos, twelves string etc.
