Spool Music supports the most common audio formats: MP3, M4A, FLAC, WAV, and AAC. These cover virtually all music files you're likely to have in your collection.
Can I organize my music into folders?
Yes! You can organize your music files into folders within the music folder. For example, you might create a structure like:
- music/Artist Name/Album Name/songs.mp3
- music/Jazz/song.mp3
- music/Audiobooks/book.m4a
When you tap "Sync Library" in Settings, Spool Music will automatically scan all folders and subfolders to find your music files. The app will organize them by Songs, Albums, Artists, and Playlists regardless of your folder structure.
Is my music stored in the cloud?
No. Spool Music is completely local - all your music stays on your iPhone. We never upload, sync, or access your music files remotely. No internet connection is required to play your music.
How do I create and manage playlists?
Tap the Playlists tab to see all your playlists. To create a new playlist, tap the "+" button, give it a name, and add songs. You can also import M3U playlist files from your computer.
Spool Music includes three smart playlists:
- All Songs: Your complete music collection in one place
- Heavy Rotation: Your top 25 most-played songs from the last 30 days
- Top Played: Your 50 all-time most-played tracks
Do I need an internet connection?
No. Spool Music works completely offline. Once your music is on your device, you can play it anytime, anywhere - even in airplane mode. The only time internet is used is when fetching album artwork, which is optional.
