### 1/5 — Genuinely bad app

*2026-05-03*

Does not say what it advertises, not intuitive and the UI is bad. It’s an app that reels you in with a free trial hoping you forget. I forgot and burned $30. Save your money and time.

### 5/5 — For the guy above

*2024-05-24*

You have to go down to the bottom and touch then hold at the end of the chord bar and drag until it is shorter, then you can fit more inside the allotted slots for chords.

### 3/5 — Meh ….

*2023-10-27*

The method of coming up with chord progressions does not give me very inspired results.

Also a note on the performance mode — they don’t really offer any performance patterns that fully support extended chords, nor give you the option to creat them. Granted - doing that might require patterns that have one version for basic triad chords and another for extended chords — but that is a measure that the developer _ought_ to be willing to take. :: Furthermore, why is live-recording the only way that it allows the creation of new performance-mode patterns? If it allowed direct _editing_ of those, that would have been _very_ helpful. They should do that.

### 3/5 — Wasn’t able to try

*2022-03-31, version 2.0.1*

Couldn't get through the registration process.

### 1/5 — Asks money

*2022-01-23, version 2.0.1*

The app isn't free at all!

### 4/5 — Cool app

*2022-01-07*

Noice!

### 4/5 — Attention with version 2.0.0

*2021-12-29, version 2.0.0*

Attention: the release notes of version 2.0.0 do not mention that you need to login now in order to use the app. I had to delete the App. It’s also sad that there are only monthly and yearly subscription models and no one time purchasing. The monthly and yearly subscriptions do make only sense for users who use the app frequently for their jobs. For someone like me who needs the app only few times per year it’s not attractive. The app itself is beautiful and intuitive. I don’t know if it has any bugs because I couldn’t use it often as I had to delete the app now. Why am I still giving 4 stars? Because the stars are only rating the implementation quality and design of the app.

### 5/5 — Cool app

*2021-12-25, version 1.1.0*

Easy and fun app to use!

### 5/5 — Useful, intuitive, inspiring, and complete!

*2021-06-01*

Even using it as a sort of, “dictionary” for chords and scales it is excellent. Very intuitive and useful for any inspiring producer, songwriter, or someone who is not well versed in music theory and would like to learn. The displaying of chords on the piano is a huge plus. I love this app.

### 5/5 — Absolutely great!

*2021-05-27, version 1.1.0*

Великолепная программа для создания простых аккордовых прогрессий! Всё просто, наглядно и эффективно. Прям то, что нужно. Спасибо!
