Doubo
Your playlists, one tap away.
A native IPTV / M3U player for iPhone, iPad and Mac. Import your own playlists, browse by group, watch in Picture in Picture or cast to the TV — no bundled channels, no data collected.
> cat ./overview.md
Doubo (都播) is a native IPTV player. Add an M3U/M3U8 URL or a local file and channel names, groups and logos are parsed automatically; the last 20 playlists are remembered and restored at launch.
One tap tests the whole playlist in parallel and lines up the channels that actually play. When a channel has several sources, switch lines instantly to the smoothest one. Playback is built on AVKit — Picture in Picture, subtitle tracks, playback speed and full-screen landscape — and DLNA casting sends it to a smart TV on the same network.
Doubo ships no channels and sells no content: you bring playlists you are entitled to use. Playlists, favorites and history live only on your device, with no ad or analytics SDKs in the app. iPhone, iPad and Mac are supported today; Android, Android TV and Apple TV are on the roadmap, alongside EPG and catch-up.
