My impression of Organic Maps immediately improved when I started driving. It talks! It knows exit numbers! It can tell you which lanes to use! Sure, it isn’t as polished as Google Maps, but all of the functionality is present. The UI is high-contrast and easy to read, although I wish the text showing exit numbers/street names was a little bigger. When you’re simply on the road and following directions, Organic Maps feels every bit as intuitive as Google Maps.
As my fiancee and I prepared to set off into the boonies, I plugged in the address of our hotel. About 45 seconds later, Organic Maps returned the 300-mile route to our destination. It can take a lot longer to calculate longer routes using your phone’s processor instead of a huge cloud server. It didn’t really bother me though; 45 seconds is nothing compared to the 6-hour trip ahead. If that’s the cost of using a maps app that doesn’t spray your personal data all over the internet, I’ll pay it.
There might be some website that offers that functionality using OSM data.
One thing that we need to understand is that OSM is data. Loads of it. The ways of displaying and searching for that data are up to each website and app that uses OSM data: first the data has to be added to OSM, then someone has to develop a tool to easily view it.
