### 3/5 — Wants to charge me again???

*2026-01-01, version 2.1.1*

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.

### 3/5 — era un…..excelente programa para guitarristas!!

*2024-02-02, version 2.1.1*

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.

### 2/5 — Probably just another abandoned app

*2022-07-13, version 2.0.4*

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.

### 4/5 — メトロノーム

*2020-10-09, version 2.0.4*

メトロノームをバックグラウンドで使えるようにして欲しいです

### 2/5 — Missing previous features

*2019-09-03, version 2.0.4*

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

### 2/5 — Chord Finder Tuning is Way Off!

*2019-03-18, version 2.0.3*

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.

### 2/5 — Not working

*2018-12-16, version 2.0.3*

Tuner no longer works???

### 2/5 — Tuner doesn’t work.

*2018-11-30, version 2.0.3*

Please fix it.

### 5/5 — とてもよい

*2018-10-13, version 2.0.3*

5つのツールが全て使える。シンプルかつ美しいデザイン。広告がない。無料のアプリとしては文句のつけどころがない。ダダリオの会社のイメージも良くなった。ちょっと褒めすぎかも知らんが。

### 2/5 — Needs work. Audio problems.

*2018-05-19, version 2.0.3*

On the first few uses it seemed great. Chord finder and scales were neat. Felt kinda clunky but worked. I actually really liked the metronome and trainer included. However once my phone rebooted, I got no more sounds. On the metronome and the chord dictionary. No audio. I rebooted, closed, reopened, reinstalled and still sounds don't work. Disappointing because it's otherwise pretty useful.

### 5/5 — Awesome App

*2018-04-16, version 2.0.3*

Very intuitive and useful 👌🏼

### 2/5 — Tuner is off

*2018-01-19, version 2.0.3*

Just discovered last night that the tuner tunes my guitar slightly flat, although the app shows that it’s in tune.

### 1/5 — Great app, needs mute button

*2024-04-11, version 2.1.1*

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

### 1/5 — Please Update

*2021-12-07, version 2.0.4*

This paid app has not been updated in a long time. Please update

### 1/5 — Fix it

*2020-06-26, version 2.0.4*

Please upgrade

### 1/5 — FIX IT!!!

*2019-04-20, version 2.0.3*

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

### 1/5 — Tuner not working

*2019-02-16, version 2.0.3*

As with D’tune, it’s not accessing phone microphone at all. Shame.

### 1/5 — Tuner is useless

*2019-01-10, version 2.0.3*

Bought a new iPhone 8 and it won’t let d’Tools access the microphone (rendering the Tuner completely useless)

Why doesn’t the app request microphone access when installed, and why isn’t there an option to do so in the setup area?

Used to love this app. Not so anymore.

### 1/5 — App keeps trying to phish me.

*2018-04-29, version 2.0.3*

Why is it still available?

### 1/5 — Tuner does not work in iOS 11....

*2017-11-26, version 2.0.3*

Boooooooooooooo...

### 1/5 — WHATS WRONG WITH CHORD FINDER!!!???

*2017-09-29, version 2.0.3*

Tried to use it today. All strings are 451hz, 1 semitone higher.

FIX THIS SOON!!!!!!!!!!!

### 1/5 — Like lots, but what happened to chord finder?

*2015-07-30*

This is a great util that I use a lot. From tuning my gat to checking out possible scales, etc. but one thing I've always absolutely loved about this app (and what I really paid for) was the Chord Finder. So why is it that since the last update of  the app that the app can't even recognise a basic C chord - played in the beginners position? 

Really guys?  Sort this out or else you will lose me pretty quickly.

### 5/5 — Excellent

*2025-11-15, version 2.1.1*

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

### 5/5 — As of 2025

*2025-11-13, version 2.1.1*

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.

### 5/5 — Great app!

*2025-03-03, version 2.1.1*

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.

### 5/5 — Awesome!

*2024-10-26, version 2.1.1*

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!!

### 5/5 — Well designed tuner app

*2024-10-14, version 2.1.1*

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.

### 5/5 — Actualización!

*2024-02-08, version 2.1.1*

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

### 5/5 — Best free guitar utility app!

*2022-02-26, version 2.0.4*

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.

### 5/5 — Underrated all-in-one app

*2020-07-25, version 2.0.4*

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!

### 5/5 — Absolutně skvělá app pro kytaristy

*2019-09-03, version 2.0.4*

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%.. ;)

### 5/5 — 👍

*2019-04-29, version 2.0.4*

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🥺
