Control4 and Sonos
You won’t find many apps that depend on third party closed source services. At least not in the official repos (there might be a few, but marked as having “anti-features”).
But imho, that is a good thing… I go to f-droid to find fully free and open source apps, for more corporate stuff you still can use the official store.
(Rant: I wish all these smart home companies fully embraced open standards like Matter… it’s annoying having to install a different proprietary app for every different brand of smart home device… F-Droid does have a Home Assistant client compatible with open standards, but it won’t work properly with locked-in proprietary systems)



If you try F-Droid Basic (their more lightweight version that doesn’t do the remote sharing thing) you can see it already, the redesign has been available there for a while.
But I have to say I preferred being able to filter by just the whole wide category and sort it by new, instead of having to pick now a subcategory… specially for things that I don’t mind so much what’s the sub-genre, when I just want to browse, not nit-pick amongst a lot of specific subcategories.
