Not sure what you are talking about, but I am not prompted to pay for updates. In fact, I'm installing some updates and new maps right now. Even the 'live' feature works. I am using the f-droid version of the app though, so maybe that's the difference?
This app is excellent. I'll probably donate. I would be totallly comfortable with doing this if they made their UI free, making osmand a completely free software.
I which I could use it on a regular computer, or if a web service provided something similar to what we get with osmand, the experience of its offline search included.
Next step would be mapillary providing a free app to contribute to their database or osmand providing a way to do it.
I haven't done it in quite some time, but if that is overly burdensome, it is also possible to avoid needing access to their servers by building a map file yourself.
I love OSM but editing is horrible. Draw a small path that wasn’t there before, pick from 500 different labels and tags (landuse:path or landuse:track?), make one small mistake, get a passive aggressive reply from an experienced editor that is basically “get off my lawn” and have your edit reversed...
Very slick, works well, offline. I guess aimed more at outdoor use than cities, or driving.
