### 5/5 — Excellent - So useful.

*2026-08-08, version 5.3.3*

A good place to keep all scores in one place.

### 5/5 — 很好

*2026-07-28*

不知道为什么打开之后啥也搜不到，不过老师们说挺好的

### 3/5 — The apps keeps restarting

*2026-07-25, version 5.3.3*

Everytime I come back to the app, it just restarts.

### 4/5 — Mostly great

*2026-06-18, version 5.2.1*

Edit 2: The app is working again. I do not know what happened as I didn't try anything different on my end (it was the same download that previously had not been working). I suppose the conclusion is that the app may stop working randomly, at which point I recommend exporting a copy of your saved scores to a local backup as I did. Afterwards, periodically try to download more scores until it works again I guess.

Edit: Thank you for the prompt response. Unfortunately, my problem is not with the website which you mentioned; that has always worked fine and was working when I first wrote the review. It is the app that has been (for a few weeks now) exhibiting the issues I described. I do not want to rate IMSLP lowly as it was otherwise a great app but is currently completely malfunctioning.

I am unable to preview any scores (the buffering is infinite, and the app claims a connectivity regardless of how strong my Wi-Fi is). The scores I downloaded are unreadable both within IMSLP and external PDF readers.

My software and hardware are up to date. I have tried restarting my device as well as reinstalling IMSLP, to no avail.

Please address this issue ASAP! Thank you.

### 5/5 — 건의사항

*2026-06-03*

너무 잘쓰고있습니다 다양한 기능도 정말많고 악보도 찾을수있는게 너무 좋아요 그런데 메트로놈과 튜너가 동시에 작동하지않는 부문이 조금 아쉽습니다 패치해주셨으면 좋겠습니다

### 3/5 — 故障

*2026-04-05*

最近ページをめくったらフリーズする
アップルペンシルで書き込みしたら固まる
動いたと思ったらペンから消しゴムになってるなどのことが起きてます。
アップルに問い合わせをしたら、メモに色々書き込んでみて反応しなかったらiPadの問題だが、そうじゃないならアプリ側の問題と言われました
メモは普通に書けました
仕事で使っているので困っています
なにか対処方法はありますか？
シャットダウンしてみたりもしました。

問い合わせしたいのですが、連絡先も分からず
よろしくお願いします。

### 4/5 — 업데이트 후 전에 작성한 Text 카피가 안되요

*2026-03-10*

안녕하세요.
앱은 잘 쓰고 있습니다.
그런데, 최근에 업데이트한 후, 전에 작성한 Text 선택도 안되고 카피도 안됩니다. 그래서 수정을 하려면 전에 작성한 Text를 지우고 새로 다시 작성해야 합니다. ㅜㅜ
저에게는 꼭 필요한 기능입니다.
빠른 수정 부탁드립니다.

**Developer response:** 불편을 드려 죄송합니다. 해당 문제는 최신 버전(5.1.4)에서 수정되었습니다.

### 4/5 — 갑자기 사진 바깥에 흰 바탕이 생기는 버그가..

*2026-03-08*

말그대로 화면이 안 꽉차고 하얀 테두리가 생깁니다! 그래서 악보가 작아져요..

**Developer response:** 불편을 드려 죄송합니다. 해당 문제는 최신 버전(5.1.4)에서 수정되었습니다.

### 3/5 — problems with the app on iPad

*2026-03-04, version 5.1.1*

Hi — I’m experiencing several:

• The app freezes when I try to type — it gets stuck and becomes unresponsive for a while.
• If I leave the AirTurn pedal on and then close the iPad, when I reopen the app it jumps forward multiple pages, and if I go back it jumps again by the same amount.
• It often lags and doesn’t respond for some time.

Is there an update planned that will at least fix the issues with the Apple Pencil and typing responsiveness?

Thank you!

### 1/5 — 문제많다

*2026-03-04*

페이지 턴도 느리고 필기도 안되고 점점 문제가 많냐?

**Developer response:** 불편을 드려 죄송합니다. 해당 문제는 최신 버전(5.1.2)에서 수정되었습니다.
