### 3/5 — skeptical

*2026-06-26, version 1.0*

would probably be great, but I don’t trust it not to steal my data or location

### 4/5 — 如果有中文翻译就好了

*2026-02-28*

如果有中文字幕就好了

### 4/5 — 不错

*2025-12-21*

不错的游戏，就是为什么下落式音游没有长条呀？^_^¦¦¦

### 4/5 — Yeah its good but

*2025-12-11*

so it works well but really needs horizontal orientation and skins added there to make it more playable

### 4/5 — 判定离谱

*2025-11-30*

判定有点离谱了，note一多起来判定就乱了，明明点上了却还是会miss一大堆

### 3/5 — 一些问题&改善建议

*2025-03-25*

-不允许导入手机内的.osz文件，对没电脑的不是很友好，建议改改
-你这bad判定是不是有点太离谱了？
-加个恒定note速度
-希望增加偏移值调整
-谱面不会显示在osu上的星极，希望改成会显示

### 2/5 — 無反応

*2024-03-19*

縦画面だと画面が狭過ぎて無反応がよく出るので横画面にも対応したらいいと思った

正直スマホでやるのはおすすめできない

### 4/5 — Landscape plz

*2024-01-20*

Amazing but please add landscape

### 3/5 — 老是闪退

*2023-12-12*

有时候不到一半就闪退了

### 4/5 — 挺好的

*2023-08-22*

满足了我对钢琴块的所有幻想
它没有速度特别慢的 但是有特别快的
它的节奏感很强 不存在我按键的声音跟他的伴奏和不上的情况
还有一点点创新多了一种形式

### 4/5 — 不懂怎么传歌😭😭😭

*2023-08-07*

哪位大佬教教啊

### 3/5 — Great game with a few BIG issues.

*2023-07-20*

The way to add songs is tedious. osu!manía songs can be downloaded from the website. You should be able to just download them straight from the phone. You should also be able to download skins and stuff. Finally my biggest complaint is that the game is stuck in portrait mode. My fingers aren’t small enough to play like normal. It forces me to play thumbs. At that point I’d just play piano tiles.

### 3/5 — Url

*2023-06-21, version 1.0*

Overall a great game, but how come the url doesn't work? This prevents me from uploading more beatmaps. Please fix as soon as possible.

### 4/5 — 好

*2023-05-13*

好

### 3/5 — Issues with uploading some maps and the hold notes

*2023-03-09*

Some songs become unplayable with certain hold note patterns and some songs just wont load
Other than that it’s pretty good

### 4/5 — 延迟和判定离谱

*2023-01-18*

问题：
1.用户无法自己调整延迟
2.上面的键隔很远（0.2s）还能被按到，这对难度高的谱要求变得比osu!里还高（
希望在下一个版本可以解决（加油！）
---------------------------------------------不会搞谱的看过来！！
1.把手机和电脑连到同一个Wi-Fi上
2.在电脑上输入那个网址（输完不要关掉手机页面！！会报错--> “/”）
3.上传你的.osz文件，这个文件是通过osu!编辑乐曲界面（edit）的[文件]-->[导出图包...]得到的

做自制谱的话是要在osu!里做的......所以（

### 3/5 — Ok

### 1/5 — unusable as of april 2024

*2025-07-09*

used to be the best port of mania on ios out there but cannot add beat maps through server anymore.. if there is a way to do this locally through files would be awesome

### 1/5 — unusable as of april 2024

*2024-04-08, version 1.0*

I used to have this game and consistently played it, it’s gen pretty fun and keeps your fingers warm when afk. One day I accidentally deleted it whilst showcasing it to a friend and reinstalled it, but lost all my beat maps. I left this for a while, before finally getting the time to add some of my beatmaps back again. The app is unusable, as in, I can’t add any maps at all. The url provided to hotdrop your files just says “no”. The only thing playable anymore is the default song, which there is only one of. Pls update ur game, it was a great mania port for mobile. Idk if this is just an issue on my end, but i’ve tried reinstalling it multiple times and its not working. There’s a number of reviews also addressing issues with the same custom maps feature.

### 1/5 — Not good

*2023-01-11*

This game has ONE song and it won’t let me add songs and there should be something for beginners it only has a few modes and there is nothing special about it

### 1/5 — Why u don’t like this

*2022-11-18*

It’s a small game not functioning and very boring waste of data

### 1/5 — 怎么自己写谱啊？

### 1/5 — Confusing

*2022-04-20*

It’s a good game but it’s very confusing I don’t know how to add songs there’s should be a tutorial of a YouTube video or something

### 5/5 — 爱

*2026-04-18*

其实可以尝试从手机文件里上传beatmap，可以更方便，总体体验不错

### 5/5 — 怎么导入歌曲

*2025-10-15*

怎么导入歌曲怎么导入歌曲怎么导入歌曲

### 5/5 — Best osu!mania port for iPhone

*2025-02-16, version 1.0*

on god this is the best one for iphone yall can trust me i wasnt paid i swear

### 5/5 — Good app, lacks features

*2025-02-07*

IOSU! is very promising. It’s fun to play and useful but there’s a lack for some important features. The ability to customize things such as skin and scroll speed would be helpful and importing beatmaps directly inside the app would save a lot of time. The app also doesn’t have a score system or really any sort of info about your plays except for a letter grade. Other than that, I didn’t notice any issues while playing.

### 5/5 — Good Game but a few more features or settings would be good

*2024-04-17*

This game literally has almost no flaws at all. Its a decent game but if a few more things were added it would be way better, like landscape mode. I just feel like I would do better there, and custom note speed and skins, or at least basic skins that could just already come with the game like arrows circles or squares. But still a good game 100% recommend!

### 5/5 — literally the exact thing i was looking for

*2023-08-04, version 1.0*

thank you for this

### 5/5 — Rate this game

*2023-05-28*

This game is very good.

### 5/5 — 希望能够完善一些设定

*2023-05-17*

希望工作室能够增加打击音效的设置，同时能够去优化打击反馈。虽然有些不足，但游戏已经很厉害了👍

### 5/5 — 喜欢

*2022-11-09*

虽然但是，为什么我上传不了歌曲啊

### 5/5 — yeah it’s good
