### 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.

### 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!

### 4/5 — Good but currently bugged

*2026-02-18*

Navigating a score with the scroll bar is currently broken, as well as jumping to a page by entering a page number directly.

### 4/5 — Great just need to fix big

*2026-01-27, version 4.3.3*

Having the IMSLP integrated into the app is incredible. I use it for conducting concerts and it has been great until lately. Recently on my iPad, when I zoom in on the score and try to write on it, the app completely crashes. Has anyone else found this to be true? Can’t have this happening during a concert or rehearsal. Can this be fixed real soon, I have a concert this weekend.

### 4/5 — well made

*2026-01-12, version 4.3.3*

good sheet viewer and it’s free

### 2/5 — 必ず　毎日　止まります

*2025-12-08, version 4.3.3*

2025年11月現在　最新のiPadで使っていますが毎日、必ず止まります。書き込みをした後は２秒待たないと次の挙動に移れないし最悪のアプリです。

### 3/5 — Plantes

*2025-11-25, version 4.3.3*

L’application est géniale, mais il y a un problème, elle plante quand on fait des dessins sur les partitions

### 5/5 — Great but it could be better

*2025-11-23*

I think they should have a feature that allows users to view an entire album from the commercial recordings by tapping on an album cover.

### 3/5 — 最近、落ちるようになってしまいました

*2025-11-12*

とても便利に使っています！しかし最近、楽譜のセットリスト内で、曲の順番を入れ替えようとすると、電源が再起動になってしまいます。対応は可能でしょうか？
iPad Pro。

### 4/5 — Great app, but list view is missing

*2025-11-09*

I really like using the IMSLP app on my iPad, but in this versions it seems that the list view in “My Scores” is not available.
The grid view looks nice, but when there are many scores saved, it’s harder to find what I need.

Thank you very much for your great work and for maintaining such a wonderful resource!

### 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.

### 1/5 — Would be Perfect, but terrible lag

*2026-02-28, version 5.1.1*

I hate to rate this App so low, but all my fingerings are on my pieces and now I’ll have to rewrite them all on another app. Suddenly there’s multiple seconds of lag when using the draw tool and turning pages

### 1/5 — Plantes

*2026-01-29*

Cela fait plusieurs avis et plusieurs années qu’il existe un bug sur l’application qui la fait planter lorsqu’on dessine sur une partition. Il est temps de réparer ce bug.

**Developer response:** Veuillez nous excuser pour la gêne occasionnée, ce problème a été résolu dans la dernière version (5.1.2).

### 1/5 — Money grabbing

*2026-01-22, version 4.3.3*

Everything you touch wants a subscription. Oh, you wanted to search for Bach? Money please. Oh you want to save your files? Money please. Oh you want to use the app without constant pop-ups? Money please. Could have been great, ruined by greed

### 1/5 — Ruined a performance

*2025-10-14, version 4.3.3*

Was performing (pianist) from the app and it glitched, turning a random number of pages at once. I am certain I tapped once. Was unable to find my place or my singer and we had to stop. This happened twice before we made it to the end of the piece. A mortifying experience. I am never performing from this app again, have moved to Piascore. IMSLP is a wonderful resource that I am very grateful for but this was a disaster. Software musicians read sheet music from needs to be absolutely reliable.

### 1/5 — PDF in Files app treated as scores

*2025-10-13, version 4.3.3*

Since installing IMSLP has taken to assuming any PDF is a score.  how is my lawn mower maintenance manual a score.  In signaling and i will just continue using the web if at all. i prefer forscore anyway

### 1/5 — Ayuda

*2024-08-04, version 4.3.3*

La app se queda en un bug al darle a la pestaña de Compartir. 

Ahora no me abre la app y no puedo acceder a mis partituras ni tengo opción de recuperarlas (más de 20GB). 

Ya probé a reiniciar el iPad, apagarlo, desinstalar la app sin borrar los datos… pero al volver a abrirla por defecto está marca la pestaña Compartir en la barra lateral y se cierra la app sin dar opción a nada.

### 1/5 — Update to uselessness

*2023-11-04, version 4.3.3*

This WAS a great app but it’s now not backwardly compatible with my iPad Air, which is still working perfectly, just not the latest and greatest. The app update offers to upgrade me to the latest version compatible with my iPad, but then goes round in circles, offering again and again. Disappointing.

### 1/5 — App öffnet sich nicht mehr

*2023-06-11*

App stürtzt ab wenn man auf den Button “Freigeben” klickt und öffnet sich nicht mehr danach. Wie komme ich wieder in die App und meine Noten??

**Developer response:** Hallo, tut mir leid zu hören, haben Sie irgendwelche Elemente geteilt oder war es das erste Mal, dass Sie auf diese Registerkarte geklickt haben? Wenn Sie einige Details an eguo@imslp.org senden können, werden wir uns sofort damit befassen.

### 1/5 — 데이터가 연결 안 되어 있으면 악보도 못 열어본다는게

*2023-04-17*

말이 되나요?옵션에서 찾아봤는데 이걸 설정하는 옵션은 따로 없는 것 같고.
유료화 전환을 위해서 자꾸 무료 이용자들의 이용 자유를 제한하는 것 같은 기분이 드는 건 저만 그런 거겠죠??
다른 스캔 어플도 이용자들이 많아지니 유료화 전환을 한 순간에 하던데 미리 갈아탈 준비를 하는 게 맞는 거 같네요.

### 5/5 — Some suggestions

*2026-08-21, version 5.3.3*

It’s a great app, and it’s free too! But I really hope we could create new folders directly on scores page, and be able to import multiple scores at once. Right now, I can only import one at a time, and if I were to create folders for new music, I would have to import the first score and THEN create a folder from that…it takes way too much time…

### 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

### 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

### 5/5 — Lovely for iPad!

*2026-02-17, version 5.0.0*

This app has made a lot of progress over the years and now it works like a charm on my iPad. Big fan!! I like that I can import other pdf scores I have from outside IMSLP so I can have all my music in one place.

### 5/5 — セットリスト機能について

*2026-02-14*

とても良いアプリです。
セットリストから楽譜を開いていると、「このページをめくると、セットリストにある次の楽譜が表示されます。」という通知が出てラグが起きるのが惜しいなと思います。
楽譜を読み込む時間なのだとは思いますが、どうにか改善できないでしょうか？

### 5/5 — Game changer for musicians

*2025-12-24, version 4.3.3*

This contains all the features you could want from a sheet music app, and instant access to most of the classical music repertoire through a direct link with the IMSLP database. No more heavy and expensive physical copies needed, music was always meant to be more accessible this way.

### 5/5 — Internationale Notenbibliothek

*2025-12-23*

Unverzichtbar für professionelle Musiker und Instrumentalisten …
Aber auch für Laienmusiker…
International von Freiwilligen gestaltet und täglich erweitert. 
Je mehr mitmachen, desto besser.

### 5/5 — Großartiges Angebot!

*2025-12-17*

Ich nutze als leidenschaftlicher (Freizeit-)Musiker Petrucci seit Jahren und habe auch das sehr empfehlenswerte Abo. Bin immer wieder begeistert von diesem fantastischen Angebot - das ist das Internet, das ich mir immer wieder vorgestellt und gewünscht habe. Danke!

### 5/5 — Thank you.

*2025-12-06, version 4.3.3*

Perfect.
