ve3jlg You may be right. In truth I really haven't used OsmAnd much at all. I generally don't need and don't use navigation and maps at all. My extent of using OsmAnd was probably half an hour. When I first installed it I fiddled around with it for half an hour to figure things out. I'm a technical person and not easily put off by complicated things, but rather quickly I felt overwhelmed with all the settings and not knowing what the hell is going on. Couldn't "get into it" easily.
Just playing around, the map layer also felt rather heavy and sluggish. The color scheme of the map also put me off as things didn't "look" as clear to me. This may be a "google" syndrome that we have all developed, if it looks different you are thrown off by "feel".
Anyway I left it to explore later and haven't opened the app since. I'm saying this to say that I may not be a good judge of OsmAnd at all because I really haven't used it enough. I also wanted to point out how easily "feel" and what we are used to can throws us off and have us not use something.
In my area (CAN) the transit system itself relies on google maps (which is sad). But its possible that OsmAnd may be on par.
The slow and sluggish feel I felt might be because of the amount of things the app is doing and how it renderes things. It would also explain the battery drain that @zehyani mentioned.
