### 5/5 — Cool app

*2023-06-30, version 1.3*

Nice work on this app

### 3/5 — If it showed Key it would be perfect

*2022-09-11, version 1.3*

If it showed the key a song was in it would be perfect for decomposing a song. But is is great for instant note recognition. I would also like drums to be ignored which would be possible with attack recognition. BPM rhythm detection would be great as would rest detection (rhythm) shown in a staff up top. Also, i wish it had a staff view. Bug in ipad mini: pressing the “rotate screen” button rotates it, but cuts off part of the circle view.

Another user wishes it would record the notes & rhythm , and it allowed export to a midi file.

So much room for improvement, so 3–4 stars.

### 5/5 — Very useful for meditation!

*2022-04-28, version 1.3*

The app does what it’s supposed to and without fuss. 🙏🏾 Very grateful!! I’m experimenting with different tones for my mantras and this app helps so much! To dev: would you consider adding a feature to change the visualizers? I would like to match the notes with specific colors like the light spectrum.

### 5/5 — I love it!!!

*2021-01-13, version 1.3*

I can play chords on my guitar and see what note it is, and then begin to make predictions where an F will be on the neck at a different location, and of another tonality!!! 

I am already loving this, but one suggestion is to add the played note on a display in middle of the circle with the associated tone/pitch number with it. E4/E6 C7/C5 and whatnot.

### 5/5 — The most fun I’ve had playing with anything today

*2020-08-14, version 1.2*

This is such a fun and simple design! I just found this yesterday. Now I’m enjoying singing into my phone and watching the notes light up.  For vocalists this is a beautifully simple introduction to perfect pitch and interval training.  Well done, Marc Arias!

### 5/5 — Never knew I needed such an app..

*2020-08-03, version 1.1*

This app has so much potential! It’s therapeutic and relaxing. Definitely keep up the good work! (: 

(The developer should consider fixing the E-flat bug though.. )

### 5/5 — Time review

*2020-08-03, version 1.1*

My lord, a top quality app. 10/10 musicians and music lovers would agree

### 5/5 — Unbelievably captivating

*2020-08-03, version 1.1*

What a fantastic and truly mesmerizing app. You can indulge in the visuals and see what it’s like to undress the music you’re listening to. Love you Mark! Great work!

### 5/5 — Awesome app!

*2020-08-03, version 1.1*

Very fun and easy to use with beautiful colors, works well
