Ranked in these QuestionsQuestion Ranking
Pro Based around crowdsourced OpenStreetMap data
OSM provides a map editable by everyone; just like the web-based encyclopedia, Wikipedia.
Using a community edited map allows one to correct isses they encounter. Combined with the monthly turn around, these edits are added for navigation quickly.
Pro Works offline once the maps are downloaded
Pro Excellent general map viewing
Sometimes one needs more than just navigation, they have a need to view a map or specify a specific route. OsmAnd provides a very nice, detailed map. This can be good for seeing what is around you or showing a place you are talking about to a friend.
It also provides a means to add waypoints on the map which can be used to dictate a specific route (not simple enough to do routinely).
Pro Routinely updated maps
Utilizing the community driven OpenStreetMap data has allowed for monthly publishing of new maps that the user can use. Though that doesn't necessarily mean the map data has changed.
Pro OpenStreetMap contributing made convenient
One can also utilize features to contribute back to OSM. This includes reporting a bug or adding a POI. This feature doesn't require an internet connection as the points can be uploaded latter upon request.
Pro Free and open source
Pro Helpful lane guidance
Lane guidance can assist in deciding if one should stay in the right or left lanes. OsmAnd provides detailed information on the number of lanes and which are valid for your chosen destination; based on the data available it may show too many or too few lanes.
Pro Contour lines enable understanding the terrain
Through the use of an additional plugin OsmAnd Maps & Navigation is able to utilize contour lines on its maps which helps view the landscape and terrain.
Pro Shows speed limit
Pro Wider availability of downloading maps from various countries
HERE maps allows users to download maps from more than 200 countries.
Pro Interactive 3D maps
There are interactive 3D maps for shopping areas and airports for 70 different countries around the world.
Pro Find places near you
You can find places to shop, eat, and almost anything with HERE.
Pro SD card support
Pro Voice-guided navigation
HERE has voice-guided turn by turn direction built into the app and is even usable when offline.
Pro Save maps for offline use
HERE allows users to save maps to their devices storage in order to allow offline usage of the app anytime.
Pro Has multilevel floor layouts for many airports and large shopping centers
Many airports and large buildings have an icon on them which, when tapped, opens up a 3D view of the floor plan with labelled locations of services, shops & transport etc. Includes an index for selecting each level of the building.
Pro Great smartwatch companion app
Excellent companion app allows navigation from your paired Samsung Gear S3 smartwatch. Has clear turn-by-turn instructions, vibration alerts at intersections, and zoomable location map (using rotating bezel). (Smartwatch app works with phone app and is not standalone).
Pro Includes public transport routing & schedules
Has train, ferry, bus etc. routes and schedules for many cities. The routes are overlaid on actual maps (spatially correct, vs the typical simplified diagrams of public transport networks) which I find reassuring and useful when exploring new locations. Also shows the schedules for next few services for any given station/stop. I'm not sure how accurate the schedules are though - they were incomplete for the small town where I live, but seemed more complete for major cities.
Pro Offline transit and walking directions
HERE is probably the only offline navigation app which has transit directions and walking directions when offline.
Con Poor navigation interface
The interface is not the most intuitive, though is continually progressing. It doesn't provide a 3D view like many navigation apps.
Con Slow rendering
It can take some time for an area to be rendered. This tends not to be a problem during navigation since only a small area must be rendered as the map moves, and this area isn't immediately needed; though likely a bigger issue with smaller screens.
Con No display when the next speed limit occurs
When driving on unknown streets you are often surprised by speed limits or town signs, so you have to friction brake.
Con Slow and sometimes poor search
Most often does not find what you are looking for (which is not caused by bad OSM data).
Con Terrible address data
This is a limitation of OSM's data, but it is unreliable for locating an address while offline. Even with internet it doesn't appear that it can locate most addresses.
Con Being based on OpenStreetMap data can be lacking
The use of OSM also has the drawback of many places not getting the attention needed for updates. Depending on the geographic location OSM may have the most detailed maps or the most bare/outdated map.
Con Near impossible to scroll through map
Due to the slow rendering (already mentioned) it is near impossible to scroll through OsmAnd's maps. You move the map only slightly and it takes ages to redraw all vector layers.
Con Map file size
Map downloads are huge in size, ranging from a few hundred megabytes, to a couple of gigabytes, depending on the size of the map being downloaded. Luckily, the app can be set to store them on external SD memory.
