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.

Refrain is a music player for the music you own: the albums you bought, ripped and kept. Bring them in as folders, and Refrain makes them into a library that feels like Apple Music, with your music the same on iPhone, iPad and Mac through your own iCloud. FOLDERS BECOME PLAYLISTS Import a folder, a zip or a few songs, open music in Refrain from Files or Safari, drop it onto Refrain on iPad or Mac, or put it in Refrain's folder in iCloud Drive from any device. Each folder becomes a playlist, and a folder of folders stays together. Albums and artists are found from the songs' tags, covers from the files and folders, and an .m3u sets a playlist's order. EVERY FORMAT, NO GAPS MP3, AAC, ALAC, FLAC, WAV, AIFF, Opus, Ogg Vorbis, Dolby Digital, Dolby Digital Plus and MP2, in their own files or in Ogg, WebM and MKV, up to hi-res. Music videos in MP4, MOV, MKV, WebM and MPEG-TS play with their picture, AV1 included on iPhone 15 Pro and later. Albums play without gaps, Crossfade joins everything else, and Sound Check evens out the volume from ReplayGain or iTunes tags. A PLAYER YOU KNOW Now Playing with the artwork's colours behind it, and synced lyrics from .lrc files, or found online for songs without them when you turn it on. The queue keeps History and Playing Next together, with Shuffle, Repeat and Continue Playing. Your library has Home, Playlists, Albums, Artists, Songs and Genres, with Top Songs, Recently Added and Loved Songs, and Search finds songs even by their lyrics. ON THE MAC Your library in a sidebar, a player that floats at the foot of the window, and a mini player for a corner of your screen, above your other windows if you like. The media keys, drag and drop, and keyboard shortcuts work as you'd expect. YOURS, EVERYWHERE With iCloud, your music, playlists, loved songs, plays and playback settings are the same on iPhone, iPad and Mac. Songs download as you play them, and you can keep a playlist or the whole library downloaded for a flight. Start on one device and carry on from the same moment on another. BUILT IN Widgets play your recent playlists, or one you choose, from the Home Screen and the Lock Screen, and Shuffle All sits in Control Center and on the app icon. Siri and Shortcuts play your playlists, Spotlight finds your albums and artists, and the Lock Screen, AirPods and AirPlay work as you'd expect. Long recordings remember where you stopped. PRIVATE BY DESIGN No account, no ads, no analytics and no tracking. Refrain has no server: your music never leaves your devices and your iCloud. Online lyrics are off until you turn them on, and ask only for a song by its name.
