We should fork FDroid and make a nostr-lightning version of it so that developers can sell their apps there. Actually I might be interested in exploring that (even though I don't like Android's programming interface)
Are app bundles on Android a thing? Something like https://ninite.com/ for the 'ole Windows machine.
Should be easy enough to add to Obtainium? Could even be a "other stuff" thing. Publish your list of recommended FLOSS apps via #nostr, and install these apps with one click. Or, obviously, install someone else's public list.
Anything like that out there already?
