Bad stuff first, 3 stars because it's awful for tuning the low E any lower for dropped tuning and I think this is important as one of the features of this app is the ability to change the tuning to a dropped tuning. Besides that, this app is truly incredible. A catalog of chords, clean and precise tuning, almost every setting is adjustable, and that's WITHOUT premium! I truly love this app

Useful, simple and accurate. The free version has adverts but they're not intrusive which paradoxically makes me actually want to look at them. The tuner is probably too sensitive with narrow parameters, but this can be changed in settings. I'm glad I downloaded it

Good app, i like that you can change the Hz and there is a great selection of alternate tuning. Downfalls? No one should be subjected to Advertisments, though they are subtle, they cover up the Hz of the string you are playing. Still worth the download.

I haven't seen any clip-on tuner that tells you the octave register number. With Guitar Tuner the display is linear and contiguous and it provides the frequency in Hz. As a bonus it also provides the equivalent of a good chord book. Very impressed.

tells you the chord of every bit of sound that goes through the mic. It gets every note perfect and on chord. this is the best i have ever seen and I've seen lot's of them but this is the best and easyest to use.

Excellent app. It's not rocket science making this sort of app, but to take care and thought to make a very simple user interface and great chord reference is really nice. Always on my phone.

easy and fairly accurate, better than some if the other tuner apps on here. Just one cockup, if you want to use a custom tuning you can only setup 5 strings!!!! As much use as a chocolate teapot 🤔☹ī¸

Extremely useful and helpful application for beginners and experienced players with chord variations and alternative tunings to choose from, it gives an excellent opportunity to investigate different styles of playing and keeping your instruments in tune.

This app has been fantastic! It is so handy for tuning my guitar but has become a wealth of information with different chord charts included. Amazing!

Lau. A. Jul 30, 2021     

Great! Maybe only the very deep tones don't get picked up but i can work around that. It's great that I can select any tuning!

I use the app. exclusively to tune my Yamaha acoustic guitar. Its as good if not better than the tuners that are selling for $20-30.00. Very impressive app. & ive tried them all

Would easily award you 5 stars but when you custom tune a 6 string guitar your app doesnt allow me to tune the high E string in the options. Only the first 5 strings.

Flo. F. Sep 15, 2018     

This is the best tuner I found, after trying lots if them... And it's free... The complainrs make no sense to me. I would not mind paying for it, It's so good...

Perfect tuner, and it also helps you learn and understand basic and advanced chords.

Amazingly usable..the 'tunings' is a feature i had on digital tuner of 'lost long ago' never found replacement till now...

Ric. D. Jan 16, 2020     

Wonderfully easy to use. I am tuning the guitar for my grand daughter. I have not touched a guitar in decades. I had two strings tuned in 2 minutes

Leg. E. Jul 29, 2020     

It download easy. Simple point-and-shoot. Best guitar tuner app that I've used in a decade

Jesus it has all chords and a lot of useful stuff for a biginer. I took short look around and... It's owesome. Many tanks to the developer. May God give you long life 😊

Dav. A. Oct 9, 2020     

It's very Cool it not only contains the tuner but chords and advanced chords that will help you play very well.

Bob. V. Jul 11, 2019     

I love playing guitar but never could keep it tuned and now at age 70 with this super easy app tuning is really done for me by a.i.! Robert Vanderford

Mat. C. Jan 24, 2021     

Must have app for guitar players. Dozens of tunings included and you can even make your own. Chord charts included.

Eva. O. Apr 14, 2020     

Great app. I use it for tuning my acoustic guitar and as reference for some complicated chords and it works perfectly

Joh. W. Nov 19, 2019     

Strange choice of notes for Open A tuning. Most blues and lap steel players use E A E A C# E (one step up from Open G). Same for Open A minor (but C instead of C#). Otherwise OK.

Everything you need to learn and nothing to confuse you. Ready access during jam sessions.

Gal. F. Sep 8, 2020     

Really works well. Recommended by our guitar camp. It is for tuning your guitar only.

Display lags behind making it tiresome to tune an instrument. It does work though with patience
