### 2/5 — Music Transpose - Key Changer

*2026-04-26*

While I am out of the app, the music stops.

### 4/5 — 挺好用，目前bug是文件不能重命名

*2025-12-26*

这一点需改进

**Developer response:** 收到，谢谢反馈，后续版本改进.

### 2/5 — 内置收费 死贵

*2025-10-14*

垃圾

### 3/5 — App won’t open now

*2025-05-05*

The app won’t open, screen will be black for almost a minute and then go back to Home Screen. I paid for the full version. It’s an amazing app please fix this bug or glitch. I can’t even use the app now.

### 2/5 — 24 dollars…

*2025-04-16*

Trying to transpose a song and I could only get 45 seconds unless I spent 24 dollars. Girl…

### 3/5 — Help

*2024-06-10*

In the iPad the app is cut out pls fix it

### 4/5 — 为什么突然不能用了？

*2024-04-18*

我是88元购买的终生版，昨天到现在为什么突然不能用了？被骗了？用不用报警或投诉？向哪里投诉？

**Developer response:** 您可以在购买页面的底部恢复购买,如果恢复失败会弹出详细的向导指南页面,请按里面的步骤进行操作. 另外,确定您购买的应用是白色图标还是黑色图标,这是不同的两个版本.如果还有其他问题请发邮件到 yueyin.music@foxmail.com

### 1/5 — Sick of the "fine print"...

*2023-08-27*

Download the app only to find out that it will only export 30 seconds unless you pay $13 for the full app. Bait and switch garbage. Tired of it.

### 1/5 — 半了vip后删除再次下载怎么没法用了？又要花钱！

*2023-08-24*

请开发者解决下

**Developer response:** 如前面沟通，新的手机或是重新安装后，点击恢复购买或重新购买（不会重新收费）即可恢复哈，感谢支持

### 1/5 — awful

*2023-08-10*

doesnt let you actually export the song

**Developer response:** I‘m so sorry! To export songs, you only need to select the directory, and you don’t need to specify the file name. Mac needs to authorize writing to some directories. You can try another directory. If it still doesn‘t work, you can email yueyin.music@foxmail.com

### 4/5 — 熄屏不播放

*2023-03-12*

为什么屏幕一熄屏就停止播放了 怎么解决

**Developer response:** 考虑到这不是音乐播放器应用，所以没做后台播放功能，后面可以考虑一下。

### 1/5 — Doesn’t Work

*2026-03-08*

I paid for the full app and it won’t open anything. The demo song works fine but nothing else imports into the app.

**Developer response:** Hi, sorry for the issue! To restore your purchase:
Use the same Apple ID as your original purchase.
Reinstall the app and try "Restore Purchase".
Re-purchasing is safe (no extra charge).
Email yueyin.music@foxmail.com if it persists.

### 1/5 — .

*2026-01-12*

키가 이상하거나 하지는 않는데 영상 길이 제한이 있는지 몇번했는데 다 중간에 끊긴거로만 추출돼요 제대로 사용을 못하겠어요 영상마다 길이도 다 다르게 끊겨서 끊기는 기준을 모르겠네요

### 1/5 — Useless

*2025-11-10*

Asks payment for first use, garbage

### 1/5 — 打开就是白屏

*2025-07-31*

好无语啊

### 1/5 — Du vol!

*2025-06-11*

Appli factice, 29,9€ et rien ne fonctionne !!!

### 1/5 — 为什么我看到的是168元才能永久使用？涨价这么快

*2024-12-22*

涨价太快了，别人88元买的没多久就翻倍了？看评论说bug也很多，交了钱出问题也联系不上公司，这让用户怎么能放心付费

**Developer response:** 您好，如果您在使用中有问题可以邮件到yueyin.music@foxmail.com。

### 1/5 — 普通に他のアプリ使った方が良い

*2024-12-11*

課金しないと45秒しか変更出来ないのは流石に短すぎる。

あと日本語が怪しい所がある。
こういうお金の取引が発生する場でちゃんとした日本語すら書けないのは論外。

よって他のアプリ使った方が良い。

### 1/5 — What is going on ?

*2024-11-08*

I have paid RMB168 for life use forever and turn out only can use once for a few days ? And now I can’t use it , the one I have transpose in file can only listen for 25 sec ??? Is it a scam ?

**Developer response:** You can click “Restore purchase” at the bottom left corner of the purchase page to restore. Hope this can help you.

### 1/5 — Don't buy

*2024-04-28*

$12 for nothing. My purchase will not restore. And there's no easy way to get to my Apple Music library. waste of time and money.

**Developer response:** Sorry, but you can click Rstore Purchase Failed at the bottom of the purchase page and follow the instructions on that page. Make sure your current apple id is the same as the one you used to make the purchase. As for Apple Music not being easily accessible, there are no plans to do so at this time due to versioning.

### 1/5 — 终身服务使用一段时间后就不能再用了

*2024-04-13*

我购买了终身服务，为什么一段时间后，就没有权限了？不能用这个功能了？恢复购买了还是一样，难道终身服务就是每隔一段时间收取88元？ 还没有办法联系软件开发的人，也不知道怎么弄。气死了。差评。
    得分高是是刷出来的吧

**Developer response:** 您可以卸载app，重新安装后尝试恢复购买，要保证您的系统Apple ID跟购买时是同一个账号。如果还是不行，可以重新购买，因为是前面购买的是一次性服务，会提示您是否要再免费购买一次，不会重新扣款，有极少用户会遇到您说的情况，按上面可解决。感谢反馈支持！还有问题可邮件沟通详细情况，谢谢！
