Organic maps is the goat, looking forward to their linux build becoming more stable
Organic Maps is great. Recently learned about Geo Share, which makes my job doing deliveries possible with Organic Maps. It basically redirects gMaps links to Organic Maps (even from food delivery apps).
I use it all the time! Works great.
Organic maps is probably my favourite osm app for general use. I still have OsmAnd for various purposes, and I use Magic Earth when driving for the included traffic calculations. I hope that Organic Maps can generate some traffic data in the future. Though, I imagine for it to work well, some sort of open sharing of traffic data would need to happen to avoid fragmentation between apps.
