Could not recommend this more - so much easier than managing multiple other streaming services (and cheaper than a VPN for torrenting)! Also recommend launcher manager (1.1.9) to make the home button go to Stremio (so you don’t ever have to see the adverts anymore, though it did take some playing with settings) and Trakt (+ Stremio add-on) for a watchlist.
Same for me - I got fed up of using JustWatch to check which (if any) of my subscribed streaming platforms had the film I wanted, open said platform, search for the film, find out it’s not actually available (or I have to pay on top of my subscription), and rage quit.
I even looked for a way to use lots of streaming platforms from the same interface, but of course you can’t do that cause DRM/lockin/etc.
