  1. 5/5FIXED! Now my go-to app for music reading!!

    My original review is left below so you can see that they took the feedback, fixed the issues, and made the app absolutely perfect for my needs! Way to go IMSLP!! Upgraded to 5 stars! The functionality of browsing and saving scores from the IMSLP database is excellent. The potential and problems lie in importing one’s own files. First, if you dismiss the prompt that tells you to use the “Browse” button when importing, you lose the ability to access any of your cloud files. There simply is no way to get to them from inside the app once the prompt is permanently dismissed. The workaround is the true disaster. When reading a PDF in the stock Files app, there is an option to “Open in IMSLP.” This will import a PDF just fine. However, THE SOURCE FILE IS THEN AUTOMATICALLY DELETED WITH NO WAY TO RECOVER IT. These catastrophic functionality issues need repairing before I can use or recommend this app.

  2. 4/5Good but could use improvements

    Hello! Longtime imslp subscriber here. Pretty good for reading sheet music on a tablet– I love that you can quickly download music that comes in with the title and composer already included for easy organization. However, it would be great if a few adjustments were made. 1. When inputing text information into a music file, use predictive text based on the scores already in the system (ForScore does this and it’s really convenient). 2. There is a persistent glitch that causes the app to suddenly quit during score annotation. 3. I usually have to zoom in to annotate scores– it would be great if there was a simple way to restore the original zoom settings with one click. 4. Ocaaaasssionally page turning is delayed by a few seconds (plenty of time to derail a performance)… if there is some sort of metric that could be displayed to indicate how hard the device is working, and/or information as to what factors contribute to the delayed turns, so they can be better anticipated and avoided, I’d appreciate that!

  3. 5/5A Useful and Well-Designed App

    This is a correction to an earlier review. IMSLP actually does support Apple pencil pro, maybe not fancier features, but certainly fine for score annotation. I haven’t used this app heavily because of my old iPad 6 was just too small, but now that I have a 13” tablet I look forward to using it more. I appreciate the integration with the IMSLP website and the organization of scores into Composer folders. I’ve had none of the battery drain or lost data issues some others have described, but will report them if I encounter them. I also purchased forScore and haven’t decided which one I will use, but I’m leaning toward IMSLP simply because I don’t need so many bells and whistles, and IMSLP is an invaluable resource. I hope that this app will continue to be developed. I think many of us would be willing to pay something for it.

  4. 5/5Love this app, however tiny critique…

    This app is everything I need and is even easier to use than its desktop counterpart, however I do seem to have an issue with changing the font on text boxes along with the opacity, colors, font size, etc. This may be a fault on my devices end, however since I do not have a stylus nor neat handwriting, this feature would be incredibly useful in the future if it were to be fixed and as of this review I would have no other criticism of this app.

  5. 5/5Amazing, Must Have App for Classical Musicians

    Wow! Hats off to IMSLP for a truly great app. Gone are the days of downloading PDFs from my laptop and sending them to a third party app on a tablet. Now it’s just the tablet and whatever piece of music I want to read next. Navigation is easy and straight forward, and the marking functions are far superior to any other app. It’s tailored with musicians in mind looking to make quick markings during rehearsals. And as a bonus, it happened to work great with my foot pedal page turner. A must have. Keep up the good work!
