PolyVinyl vs Null Player

PolyVinyl brings Apple Music and local music (MP3, FLAC, WAV, AAC and M4A) together in one unified library, combining online listening, offline collections and music management in a single experience. With an immersive interface, it supports lyrics, queue management, Play Next, Shuffle, Wi‑Fi upload, WebDAV import, artwork replacement and track metadata editing, and is optimised for iPad to make listening, organising and browsing music feel more natural and fluid.

Null plays the audio files you already have, MP3, M4A, AAC, WAV, AIFF, FLAC, whatever you've got, without an account or an internet connection. Import files from the Files app and Null reads the title, artist, artwork, and length straight off the file itself. Build playlists, reorder them, give them a cover photo, hit play or shuffle. The full-screen player has a soft moving backdrop pulled from the album art. Lock screen and Control Center work the normal way. skip, pause, resume, without opening the app. There's no account system, no analytics, no ad network. Nothing about how you use Null goes anywhere but your own phone.
