I’ve tried using it over the years but I never liked it because there was no information. So last night I looked at my local city and there is almost no information at all. I spent a few hours last night adding buildings and restaurants and removing incorrect items. It was actually kind of fun and therapeutic and I plan to do more of it tonight. My girlfriend thinks it’s dumb and I’m wasting my time because Google maps and Apple maps and Bing maps exists but she just doesn’t understand open source.
Edit: Apologies, I just realized this question is not Linux specific.
OsmAnd is my family’s go-to app for navigation. I didn’t notice it missing information compared to Google Maps. The opposite really, with several hiking trails or small side-roads not being on Google some years ago. The only issue it has is navigation for more than ~200km at a time. Often, it just times out if you try that. That’s why Google Maps is still installed on some devices.
I haven’t added anything actively. I think I might have enabled an option to send location data to improve the accuracy of the streets or something at some point, but I’m very unsure about that one.
