IMSLP

The app mostly runs fine. But it can be really buggy when importing pdfs from over places (Sibelius, CPDL etc). It works fine intially, but close the app and come back to it the next day and the file is listed, but will not open. I also experience the issue that pages are blurry/pixelated when turning. These issues are not constant but make the app useless as a performer. I also couldn't find any troubleshooting tips online for these problems or contact the developer directly about them.

The app is extremely well designed, both in terms of searching for sheet music and recordings on IMSLP, as well as for viewing scores and listening to recordings that you have already downloaded. PDF annotation works well, allowing you add musical symbols or custom drawings and handwritten text with your finger or stylus, or add text boxes that you can type in with the on-screen keyboard. All annotations are erasable, and typed text can be edited after it has been saved to the score. The app manages to strike the right balance between free content and content that requires a subscription, and the subscription itself is priced very reasonably. For the record, everything that is free on the IMSLP website is free in the app, and if you do opt to take the subscription it is valid for both the app and the website. If you already have a subscription to the website then that is also valid in the app. Overall the app has a premium feel that is not at all compromised in the free version. It is a far more convenient way to access IMSLP than using a web browser on a mobile device, or transferring scores from a PC via Dropbox or similar as I was doing before this app existed.

I love this app but 2 things would make it perfect. Firstly the audio player should have controls for pausing and rewinding a short way, visible on the score view, so that you can practice sections to audio. Secondly I would love to know the location where my imported pdfs are stored on my tablet.
