### 5/5 — Great app to learn Sky: Children Of The Light music in!

*2026-02-22, version 2.4.8*

Great app, helps me to learn music practise :3

### 5/5 — 增加乐器

*2025-12-04*

希望能和光遇里的乐器同步

### 4/5 — The app is great, make the app resizeable

*2025-11-22*

I really love this app, it makes reading and writing music so much easier, I use this app all the time when im playing instruments on sky, but ever since the update, while I like the new features, the screen is so much bigger now, writting music is now a struggle, switching screens, and above all now that the screen is a lot bigger, (since I use both sky studio and sky cotl at the same time) it is so much harder to play and read music in sky since sky studio app takes up most of the screen now. All I ask is that if yall can make the app resizeable so everyone can use the app in the size they wish to best fit their experiance.

### 5/5 — 好评

*2025-11-21*

这个软件虽然没有光遇那么好，但是还是挺好的

### 5/5 — Please make it Ipad accessible!

*2025-09-27*

This is an amazing app! I do hope you guys can at least make it ipad accessible so we can practice with a bigger screen too since I play Sky on Ipad!

### 4/5 — 增设乐器

*2025-08-04*

软件很棒，经常用来记录和弹奏生活中喜欢的旋律。希望可以和光遇游戏里的乐器种类同步，这样在弹奏时可以有更多的乐器选择。

### 4/5 — Rlly good but...

*2025-07-25*

This game is so much fun and good to practice but I don't know how to add the music sheets to the actual game, pls tell me how, thank you!

### 5/5 — 1

*2025-01-08*

我感觉这个软件对我们新手小白来说还是挺好的，在光遇上有点社恐练琴的话可以用这个软件来练琴，这个软件还是比较好上手的，就是感觉音调太高了，跟光遇的有点不一样，可以在调音这方面加以完善一下，但总体来说还是非常不错的

### 1/5 — the music cant be hear

*2024-10-04*

this is making me mad i cant hear a thing at all. PLEASE fix this ASAP ur game is broken i cant hear but the game is smooth though. ITS A BUG!!! please im desperate fix this.

### 4/5 — Good app, Bad bug

*2024-03-22*

I like using this app just for a hobby, or practice for the actual sky game, good mechanics and everything. And I like the change of instruments and pitch. Problem is, there’s a bug that causes your saved work to be all deleted/completely changed into a jumbled mess. Other than that, I like making songs, wish I could keep them though.
