## Most critical reviews (10 lowest-rated)

### 1/5 — Battery Drainer

*2024-03-01*

This app is either incredibly unoptimized, or running things it shouldn't in the background. It will make even an iPad Pro M2 drop battery unusually quickly and get very hot. This app could be useful, but it needs an update.

### 1/5 — Tout pourri

*2011-10-19*

Et en plus ça coute très cher!!!

### 2/5 — doesn’t include ukulele tunings

*2022-02-02*

why no uke tunings?

### 2/5 — Ipad app issues with ios8 update

*2014-10-08*

Onboard iPad keypad opens with Byell harmony program and will not close... meaning you can't see half the screen...I just purchased the program today and it is essentially useless until this gets fixed! Otherwise, the program is an outstanding learning tool.

### 3/5 — Ausbaufähig

*2012-02-13*

Gutes Tool. Klasse wäre wenn man eine Kirchentonart z b a-lydisch direkt anwählen könnte. Denn so muss man sie sich relativ mühsam über den zusammenhang der dazugehörigen basistonleiter herleiten. Ansonsten sehr gut.

### 4/5 — Useful

*2022-06-04*

Can’t really complain because it does what it needs to do, which is display scales on the fretboard. I’ve learned a lot in a short amount of time using this app.

### 5/5 — Atualização

*2021-08-25*

Por favor atualizem esse APP, e incluam também um novo instrumento o UKULELE. Esse app é 10 não o abandonem, por favor. Obrigado

### 5/5 — Excellent pour la théorie musicale

*2020-05-03*

C’est mon outil de référence pour travailler mes gammes, ou retourner les notes d’une gamme que je ne connais pas.

### 5/5 — 十分好用

*2020-04-03*

目前耗电太快了，就这一个缺点。希望更新！

### 5/5 — Огромнейшее спасибо!

*2019-02-27*

Пожалуй это не только лучшее БЕСПЛАТНОЕ приложение в AppStore, но и самое полезное и удобное пособие по гармонии, которое я видел в жизни! Огромное спасибо за Ваш труд!

为严肃的弦乐器玩家，推荐，很丰富。

### 5/5 — Incredibly Comprehensive & Necessary Musical Tutor!

*2012-05-02*

This is the only musical study help you will ever need. It successfully explains all there is to know about music theory, and it really makes the process easy and fun. 

You are in full control of the information you wish to discover and there are many ways to compare scales on different instruments, in notation, the related chordal theory, modes and everything else you could ever need for proper musical development.

The scales can even be customised, as can all the chords, with all possibilities suggested as you go. You can even create a chord and then move through the cycle of 4ths to see how the chord relates to each new key. Everything is covered in this app and it's all within easy reach, it's really is a necessary experience that will satisfy you through your whole musical life.

You can also hear all the scales, notes and chords when you need to, which is incredibly helpful for true understanding. There is also full MIDI compatibility, enabling you to play notes into Byell, but also letting you use other sound sources for all the chords and scales you create. 

This really is a fun and addictive learning machine, that covers all your needs and but also goes much further. You really shouldn't be without this app if you are serious about music.
