Reporting a problem
To help us fix it faster, please include:
- your device, for example iPhone 15, iPad Air, MacBook Air or Apple TV 4K;
- your iOS, iPadOS, macOS or tvOS version;
- the app version;
- where the music is: an SMB share (and the NAS or computer that serves it) or a folder on the device;

- if one file is the problem, its format, or the file itself if you are happy to share it.
Questions
How do I add my music?
On iPhone and iPad, tap + on the start screen and choose SMB Share or Local Folder (a folder from the Files app). On the Mac, use Libraries → New Library… and pick an SMB share or any folder. On Apple TV, open Sources and choose Add Source; Apple TV plays from SMB shares. For a share, enter the server, the share (with an optional folder inside it, for example music/rock) and a username and password, or leave the username empty to connect as a guest. STMP then scans the folders and reads the tags; you can start playing while it works.
Is there anything to play before I add my music?
Yes. STMP comes with a small built-in demo library of original music, so you can try the player, the playlist and the meters right away.
STMP can't find or reach my server.
On iPhone, iPad and Apple TV, STMP needs Local Network access to talk to a share on your network. If you declined it, turn it on in Settings → Privacy & Security → Local Network → STMP (on the Mac: System Settings → Privacy & Security → Local Network). Check that the device is on the same network as the server, that SMB file sharing is turned on there, and that the server name or IP address, share name, username and password are right.
Which formats does STMP play?
Audio: MP3, FLAC, WAV, AAC, M4A and M4B, Ogg, OGA, Opus, AIFF, CAF, AC-3 and E-AC-3. Playlists: M3U, M3U8 and PLS. Tags are read from ID3v2, iTunes/MP4, Vorbis comments and RIFF INFO, and cover art from the file or from an image such as cover.jpg or folder.jpg in the same folder. On iPhone and iPad, Ogg Vorbis files show their file name instead of their title, because the system does not expose those tags there; the Mac reads them.
How do I listen to internet radio?
Put a playlist file (M3U, M3U8 or PLS) with the station's stream address in your library and play it, or add it to the playlist with Add Files… on iPhone and iPad or Playback → Add Files to Playlist… on the Mac. Stream entries play as radio, and Icecast and Shoutcast stations show the current song title.
I changed files on my share. How does STMP catch up?
Use Refresh: STMP rescans the folders and reads again only the files that changed. Full Update throws away the library and reads every file again, which can take a while for a large collection. On the Mac they are in the Libraries menu (⌘R and ⇧⌘R), on iPhone and iPad in the refresh menu on the Browse screen, and on Apple TV on the Sources screen.
Can I listen offline?
On iPhone and iPad, long-press a folder and choose Download for Offline. The files are copied into the app's own storage and play without a connection; manage them in Downloads. Music in a local folder always plays offline. Your share itself is never changed.
Does STMP collect my data?
No. There is no account, no analytics and no tracking. STMP connects only to the shares you add and the streams in your playlists; the details are in the Privacy Policy.
