"body": "I loved IMSLP very much and have been using it everyday. Today, a unexpected thing happened—when I log in that account with my other iPad, some of the pieces are missing, including one that I studied for a long time and had a lot of important notes—and all is gone!! I am very frustrated today and I hope this wonderful app could be better and I look forward for a response of how can I get it back, Thanks",

"rating": 5,
"title": "A Useful and Well-Designed App",
"body": "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.",

"title": "Love this app, however tiny critique…",
"body": "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.",

"title": "Good but could use improvements",
"body": "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!",

"title": "Gone too far",
"body": "I love using imslp to keep all of my music, but the new updates have gone too far. First, you made it so you have to wait 15 seconds to search. I get that. But now you are literally removing the search function unless the user has a subscription. If you want to make money, I understand, but you have to keep in mind that the purpose of this is to benefit everyone, not just to make money. Edit: Thanks for clearing that up, I’m truly sorry. I realized that you could also search for the piece you want if you know the composer. Sorry again for the misunderstanding.",
