### 3/5 — Great app but…

*2024-10-16, version 1.0.1*

7 years without updates has accumulated errors. Now in iOS18 the app don’t allow configure the exercises. I’m daily user, please fix it. Thanks in advance

### 3/5 — Is not working

*2024-01-28, version 1.0.1*

I loved this app, it’s really helpful for practicing sight-reading, however the app is not working now, what happened? I paid for the premium version, but now is not working, fix it please!

### 4/5 — Please add landscape layout for Ipad

*2023-11-23, version 1.0.1*

Would have given five and bought it if there were a landscape layout. Otherwise its pretty useless on ipad. :((

### 1/5 — Doesn’t work

*2023-01-08*

Worked for a bit then stopped working

### 4/5 — Amazing and free

*2021-08-15, version 1.0.1*

Would like to have landscape layout
Not very convenient to use on ipad

### 1/5 — Bad

*2020-07-13*

Me doesn’t like

### 5/5 — Amazing

*2019-10-02*

Perfect for anyone trying to practice reading music sheets, and cheap for the pro version, it made it easier for me to learn the different signatures, instead of googling one by one, I get it for free in the app
Just amazing

### 2/5 — Upgrade glitch

*2019-02-01*

I would’ve given this 5 stars if it weren’t for the upgrading issues. Every time I upgrade to the premium version, my premium is reverted back to basic. It tells me that if I’ve purchased the premium version already, all I have to do is purchase it again and I won’t be charged. However, every time I do this, I’m still charged. What’s the deal?

### 3/5 — Nearly very good

*2018-11-10*

My daughter has been using this to help with her sight reading. The right hand is excellent however in the left hand when you change the note range the displayed keyboard does not move to match the range. With this one change it would be excellent.

### 5/5 — Wonderfully done.

*2017-01-16*

I can already see a huge positive difference in my note memorization goals. What a time to be alive!
