If you're talking about the FOSS app, it's just a nice UI for your RealDebrid web-interface. It can:
- tell you how many days you have in your RD subscription & your RD points
- list the RD+ streams you've clicked on/watched so far
- stream your RD files, share em, download, all that.
- download from link/magnet using RD servers
- search through popular indexers (which RD can't do, but Torrentio does it) and optionally add them to you RD library
But as far as I can tell, it's nothing you can't already do with the RealDebrid webpage & the stremio interface with Torrentio. Unchained looks nice though.
Edit: clarification.
Ahhh yes, google dorks, the duller brother.
