This is my old review pointing some cons of Amperfy: It’s definitely the best free app that works with SubSonic and Navidrome, but it has some big problems: - The downloads (or “cache”, are the same thing on Amperfy) is a mess, it will download all songs you play (unless you opt-out) and you cannot bulk delete specific songs (aka select the songs you want to delete), you delete one song, or you delete the entire library. - Buggy notifications that you cannot swipe will block the top of your screen, this is so annoying. - The player looks ugly on older iPhones (maybe on newer too I tested on iPhone 7) with an unused space at the bottom of the player and no enough space for the UI at the top. When these problems get fixed I’ll happily change my my review to 5 stars. Some other things that can be included to make the app better are: - Option to refresh the library to remove missing albums. (I have to click the album to make it disappear after deleting it from the server.) - Option to start on Offline Mode when long pressing the app on home screen. — Now this is my review after some updates: I’m happy to see that the app is improving, the “cache” was changed to a more user-friendly nomenclature, “downloads”. It works nice with Siri and the option to prevent the phone from turning off is awesome! I love to see one of the few clients available for Subsonic that doesn’t lacks in basic features getting updated with more useful features.
