Hello! I'm looking for a foss navigator app for my android device, but all navigator apps I've tried (OSMand, organic map) are missing a feature: when I calculate the route from point A to point B, on Google Maps a few possible routes are displayed, and then I chose the one I prefer; on other apps only one possible route is displayed, and if for any motivation I don't want to pass from a certain street or something like this, I have no other options. Is there an app (or a way on these apps) to make it calculate a few possible routes instead of just one?
I also don't understand why I can't be shown 2-3 options, it's incredibly convenient. Manually adding waypoints, or manually telling it to avoid roads, isn't and it's also not the same thing. On Google I see whole alternative routes, in osmand I only see an adapted route when I make a change (waypoint/avoid), but I still only see that one route now. I no longer see the old one to compare, and switching back is cumbersome.
I don't really understand why a few options aren't shown as a default, maybe with slightly certain criteria if possible for a particular a to B. Like one avoiding highways, or hills, or just smaller roads. Maybe a shortest and a quickest, maybe one with fewest lights. If that's not possible, just show some comparable options with similar travel time? Would really improve the experience a lot.
We're talking about servers storing tens or hundreds of gigabytes of map data in RAM. Your phone doesn't even have that capability. That's why calculating a route on OSM is slow and Google is fast
