Tuneline is a cross-platform media player built around one idea: set up your library once and never rebuild it on the next device.

You bring your own playlists, and Tuneline keeps everything else in sync. Your favorites, watch history, program guide, and settings are already there on every device you sign into, including a brand-new one. No re-importing, no starting over when you switch phones.

What it does:

• Cloud sync for playlists, favorites, and settings across all your devices

• Native apps for macOS, Windows, Linux, Android, Google TV, and iOS, from a single Flutter codebase

• A full program guide with reminders you can push to Google Calendar

• An on-demand library with season and episode browsing

• Global search across your whole library

• A web dashboard to manage everything from any browser

• A cinematic dark interface designed for the big screen

Every viewing feature is free, forever, on one device. A one-time purchase adds cloud sync, cloud backup, and multi-device. No subscriptions.

Tuneline does not host or provide any content. You bring your own, the same way you would with VLC or Kodi.

Under the hood: built solo with Flutter and Dart on the client and a Node.js backend for the sync layer, shipping the same codebase to six platforms.
