Wants to charge me again???

This is app does a decent job in all its functions. But with the new update it’s requiring me to repurchase the upgrade that includes Buzz Feinten. And there is not “restore previous purchase” button.

Excellent

Great, easy to use tuner and easy to access metronome. I use the tuner more than my Peterson.

As of 2025

I have used this app reliably for over a decade now. It is a no muss, no fuss, tuner / metronome / chord library.

No hidden in app purchases or subscriptions. Highly recommend.

Great app!

I have had no problems with this app so far. I am also a member of D’addario’s players circle, and I was so excited to see they made an app that I could use with guitar.

Awesome!

This is a great app. It works well and is loaded with everything you need to help get in tune, practice and play. Thank you!!

Well designed tuner app

Fast responses.
Variety of GUI choices.
A=442 set-up is for free.
Design is superior than most other tuner apps.

Wish it had sweetener features, but still a five star without it.

Great app, needs mute button

Very pleased with this free app. Really wish it had a mute button for the metronome so I can hear it and then mute it while playing instead of having to use the volume button. Thanks!

Now it doesn’t work on iOS 12.5.7

Actualización!

Por fin! Actualizaron la app y ahora funciona a la perfección… y mejor aun: GRATIS!

era un…..excelente programa para guitarristas!!

Deberian actualizarlo y darle soporte……la reseña que hice hace años era excelente pero ya no lo es mas……… hace mas de 10 años: Este es una de las aplicacines por las que queria un ipod touch 4 g , funciona a la perfecccion, muchisimas posiciones de acordes, aparte puede detectarte alguno que no sepas como se llama, las escalas son muy buenas , el afinador es impecable, el metronomo siempre es util, en fin es un programa que vale mucho la pena y el precio es casi de risa, es una aplicacion que todos deberias de tener lo recomiendo ampliamente.

Probably just another abandoned app

App offers a few functions, which might be very nice if they were usable. Maybe it just doesn't work on my device, hard to tell.

When you run the app, there is a choice of functionality. You can select e. g. chords, but there is only E major and its inversions, no possibility to change chord, no possibility to get back to other parts of application.

Best free guitar utility app!

PROS: The chord diagrams are a beginner’s best friend! I often time find myself learning new 7, 9, etc chords. The chord finder is a must for experimenting with different triades and can help creativity and writing. Scales are a god send and decently accurate although I can’t find a 3 per string for the major scale that I use. The app is also FREE.

Cons: The tuner could use a touch up. It isn’t the most accurate, mic sensitivity can me an issue in a loud room. The metronome shuts off if you close the app which is annoying but you can set it to prevent sleep which keeps the app open during play/performance. If these 2 things could get worked on… I’d be one happy camper.

But hey, the app is free so you really can’t complain! I’d recommend Chordify for jamming along chords to songs, Ultimate guitar for tabs, and D’Tools for practice/checking your work.

Underrated all-in-one app

Was playing around the App Store to check if there’s a d’addario app or smtn then I found this app. Before this app I previously had 3 apps just for guitar tuning and chord finding. Design wise could use a little bit more but from a functionality stand point, it’s really good! I recommend it!

Fix it

Please upgrade

Absolutně skvělá app pro kytaristy

Jednoduchá, ale naprosto skvělá aplikace pro kytaristy: stupnice, akordy, “hledač” akordů a metronom. Jde viděti, že tady autoři uvažovali hlavou. Jediné co mi chybí jsou mody stupnic (scales mode). Pak by to bylo čistých 100%.. ;)

Missing previous features

Previously all the modes were available. Now they’re missing. Please fix.

👍

コードの指番号のところに度数又は音名を表示できるようにして欲しい。
度数と音名を同時に見たいので…

スプラッシュ画面の表示が長過ぎる気がする…

よろしくお願いします🥺

FIX IT!!!

The app is out of tune!!! Useless! Fix it!

Chord Finder Tuning is Way Off!

Most of the app seems fine, but the sound of the Chord Finder is about a whole step too high. I can’t find an adjustment except for the tuner, whatcha was actually set at 432. I changed it to 440. No difference. Looks like it’s no longer supported either. Too bad.
