### 1/5 — Microphone

*2025-10-27, version 2.25*

No microphone settings in app or in apple settings.  App cannot hear chords

### 4/5 — Fantastic tool for beginners.

*2024-01-20, version 2.25*

Great little app to keep you motivated by letting you see your improvement from attempt to attempt, a must for beginners.

### 3/5 — Audible Timer Needed

*2023-09-19, version 2.25*

It would be great if there was an audible signal when time is up. Also having the app use the mic to count would be great.

### 4/5 — Almost Perfect

*2023-08-10, version 2.25*

Only given it 4 stars as it does not add up the chord changes for you if it did it would be perfect fora beginner like me and I would be happy to pay for it.

### 5/5 — From a complete new bee 🐝

*2023-05-02, version 2.25*

Just getting started and have found Justin’s style of teaching works excellent for my particular  style of learning and pace preferences. His chord change app has been really helpful. I am so grateful I have found this and just started using it 2X a day. Highly recommend ⭐️⭐️⭐️⭐️⭐️

### 3/5 — Is the app still working?

*2022-10-25, version 2.25*

On a iPad, the app does not orientate itself and does not count correctly.

### 3/5 — Looked everywhere no android

*2021-11-22, version 2.25*

Really hate android but needed to find a dl and I guess there is none. Sad

### 3/5 — Repeats the same changes

*2021-09-20, version 2.25*

Repeats the same changes over and over and never really gets to the harder stuff like F, Bm and changes with them.

### 5/5 — Wonderfull to exercise code change

*2021-08-24*

Easy to setup what I want to remeber. Very nice idea!

### 3/5 — Glitchy but useful

*2021-06-25, version 2.25*

There are problems with adding and editing chords, and the interface is not very well designed. But you get what you pay for.
