So I just looked into this because I don’t seem to be missing any “essential features” and it seems that there are major differences between the corporate Store version and the F-Droid version that I use. Pretty hard making sense of it all but it seems that on the FOSS version some otherwise paid features are free (including map downloads), I guess because there would be no mechanism to charge for them when there’s no app-store account. Others don’t seem to be available at all, but apparently I don’t want those.

Anyway, the fact that they publish on F-Droid is the reason I’ve used this app for over a decade and why I never miss an opportunity to shill for it, like right now. Which I hope counts as payment in kind.
