No because I don't have an account

Hehe

The thing is that Google accounts aren't only used for mail though; reliable access to the Play Store through Aurora, as well as access to paid apps, needs a Google account for instance

To still sorta replicate that, I just set up a script at /usr/local/bin/update for it:

#!/usr/bin/env bash

sudo emaint sync -a &&
sudo emerge -utDU @world &&
sudo emerge -c;
flatpak --user update;
doom upgrade &&
doom sync &&
doom purge

Yeah I prefer Neo Store but they both are really solid

Go with Neo Store rather than the F-Droid app; it has a better GUI, supports adding other FOSS app repos like IzzyOnDroid, and does a pretty good job keeping apps up to date actually
