i use f-droid for most apps (Free and open source), and aurora store (its on f-droid too) for google play apps. technically, aurora does access google play servers to get those apks, but so does any other site that would share those apks, so… no account is needed for this, btw.
generally, avoid downloading apks from the internet, its risky af.
true i forgot about accrescent. it only has a small handful of apps tho that are also just on fdroid
