dsdx331 Whats your opinion about using aurora store + appverifier for each installed app?
It's not the end of the world, as long as the app doesn't check the store it has been installed from.
The source of the app would be the same either way, and you can still check the signature as you mentioned.
I would also suggest APKUpdater. It has a slightly different UX, but you can get used to it very quickly.
