(This is not meant to be a proposal to add this as a PG recommendation, but a general discussion.)
I recently discovered an app called Vela which is an Android maps app that combines data from OpenStreetMaps, Google and others.
So for example the maps themselves comes from OSM, but the traffic info (used for finding the best route), shop reviews and photos, or streetview images comes from Google. It does not require Play Services (unlike Google Maps) and they say there that less data is transferred to Google (e.g. instead of constantly transmitting your location to Google while your drive, it only occasionally checks if the traffic has changed on your route or if another route would now be faster).
Which in my opinion in an interesting approach, because it only uses Google data for those things where Google is clearly superior to 100% FOSS options - e.g. streetview, shop info, live traffic. So it’s a realistic compromise between complete degoogling on the one hand and having access to the best map data on the other hand.
I have played around with it for a bit. It’s still a bit rough around the edges, for example it won’t yet show you the public transport route visually on the map but only tell you instructions “take this train, then that bus”. Though to be fair, for public transport there are many excellent FOSS apps already. I also noticed that the ETAs for driving can differ between Vela and Google Maps, even though Vela supposedly uses the exact same traffic-aware routing as Google.
Also the whole thing appears to be assisted by AI, though I don’t know to what degree. I don’t mind AI per se, but I’d like to avoid apps that are completely vibe-coded. Not sure if this is the case here.
