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 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 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 Free and open source
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 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 Shows speed limit
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 Offline functionality
You can download offline data per city or parts of cities if you live in an especially large city, but not for states or countries. Points of Interests are generally more relevant & current than the typical stand alone GPS unit.
Pro Best execution of save location feature
Recent updates have made it so you can label a place instead of being stuck with some address or GPS coordinate and forgetting what it represents. Saved places show as stars and are all on one layer as long as you're logged in. There is also the ability to create maps (parallel to groups) for things you might not want to see or have show up all the time whenever you're using google maps from day to day.
This feature is highly helpful for planning, even if you're a person who likes to wing it.
Pro Find your parked car
You save the location of your car and easily find it again
Pro Accurate mapping
Pro Updated constantly
Nearby my house, there is major road construction in progress. Apple maps didn’t show this at all, but google maps did. There was also a new, small road that was finished around 3 days ago. Google maps shows this road. Apple maps still hasn’t shown the major construction.
Pro Most ubiquitous third party app integration
Asides from the stock Apple Maps app, Google Maps is the most commonly supported 3rd party map. 3rd party apps often have links for directions, Google Maps is usually an option whereas other 3rd party GPS apps are not.
Pro Navigation background change based on ambient light
This is great for night driving or even when going through tunnels as the map will be more visible for low light situations.
Pro Secondary routing
Google Maps can now search for and add a route for a second location on the way to the primary location that you are going to and have already routed. Note that it cannot do a third or true multi routing like the desktop webapp can.
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 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 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 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 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 No plan-ahead for commuters
Cannot plan trip ahead based on commuter lane.
Con Not very precise traffic information
Depending on a country information might not be very accurate for traffic.
Con Sometimes takes too long to load
Con Saved locations needs online connection and has no visible label
Two negatives about this feature is you have to be online to be able to save a place, but it is stored off line once google map gets on the net and syncs. The other negative is there is no visible label for saved places, you have to click on stars to see the label for them.
Con Maps saved offline can easily wipe your bandwidth cap via auto update
Google Maps offline maps update automatically in the background. Not a problem if you're using a sim card in your phone, but if you connect to a pre-paid hotspot that the phone recognizes and connects to as a wifi device you risk burning through your data allotment. The offline maps can be set to update manually, but this is not default behavior.
