### 5/5 — Amazing!!!

*2026-03-07, version 9.0.6*

This is such a good app I love how easy it is by the way I am the developers nephew

### 5/5 — Love this

*2025-10-17*

As a person that is trying to understand how more complex chords work and, this app is exactly what I have been looking for.

### 5/5 — Absolutely perfect

*2025-07-18*

This app has been incredibly beneficial for me. And the developer has been simply amazing and genuine

### 1/5 — Sacanagem, comprei a versão e ainda fica parecendo anúncios

*2024-01-14, version 8.10.1*

Comprei a versão pro e ainda continua aparecer anúncios

### 5/5 — Great app and developer

*2024-01-02, version 8.10.1*

Bought this app recently and it’s proved to be both versatile and fun. The developer is very active and is looking for ways that they can improve the scope and functionality of this app. I believe there are a number of enhancements in the pipeline that will improve its integration with other apps and overall creativity. I look forward to seeing these enhancements over the coming months!

### 1/5 — Terrible

*2023-10-08*

Developer advertised this on reddit asking for a flat fee for complete access to the app.  He has since deleted his post, and is trying to charge early backers a subscription fee.  Basically he sold his app to us, then said if you want to keep using it, give me more money.

Avoid.

**Developer response:** Hey, sorry for what happened.  I admit introducing the subscription was a mistake, at the time I didn't have the coding ability to let initial users keep their purchases.  Anyway, i've recently rebuilt the whole app and with GPT's help I'm properly in charge of the purchase mechanism now, so if you would like me to send you a code to restore your original one time buyout then just let me know.  If not then no hard feelings.

### 2/5 — I need to go below middle C!

*2023-04-25*

The whole concept of this app is great but please let us go into the lower range!

**Developer response:** I've just completely rebuilt the app, please check out the updates

### 1/5 — Developer is dishonest

*2022-07-25, version 7.5.02*

Friendly reminder that this developer lied to advertise his app and stole money from people.

**Developer response:** As I have said before, send me an email at scalenumbers101@gmail.com with your details and I will refund you your $3.20 immediately.  If you don't want to use the app on a subscription model then uninstall it.

### 5/5 — It seems a lovely app

*2020-10-22, version 7.3.2*

One doubt: I just can’t find Bm7b5. Could you help me?

### 1/5 — Awful

*2020-09-02*

I paid $3.20 for this app when it first came out in order to remove ads and get the unlock pack. Then it updated and I don’t have those things anymore and have to pay .99 a month to remove ads. Horrible.

**Developer response:** Hey, sorry for what happened.  I admit introducing the subscription was a mistake, at the time I didn't have the coding ability to let initial users keep their purchases.  Anyway, i've recently rebuilt the whole app and with GPT's help I'm properly in charge of the purchase mechanism now, so if you would like me to send you a code to restore your original one time buyout then just let me know.  Apologies again.

## Version history (last 5 releases)

### 9.0.9 — 2026-08-07

Added some extra crash logging so I can track down where a crash is coming from.

### 9.0.8 — 2026-07-01

When you open a tab or chord chart, the app now auto-loads the necessary chords and puts you in the right key.

If you have any issues, if this update breaks anything etc then let me know at support@scalenumbers.com and I'll fix it straight away!

### 9.0.7 — 2026-04-01

Chords can now be auditioned from the chord picker menu, and can be specifically voiced on generation, instead of always being created in a raw formula.
This now matches the behaviour of the Inky AU/VST plugin.

### 9.0.6 — 2026-02-23

Updated the chord pad save files to be compatible with the new AU/VST plugin.  

I'm confident the auto update logic will all be fine, but I don't want anyone to lose their compositions.  If you've made any recordings/globalSave files that you're really attached to, please back them up before updating.  This way, if anything gets messed up when your old files are being updated to the new format, you could send me the backup files to fix manually for you.

### 9.0.5 — 2025-10-21

Made it so the chords sustain-mode can be toggled in the humanise presets.
Also fixed a few bugs in the recording section.
