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. See More
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). See More
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. See More
Sygic's interface is tailored to navigation. While viewing maps in 2D is possible, it populates the map with a bunch of POI icons which detract from street names. The biggest issue is how easy it is to select something or start navigation when zooming in/out. Still usable for map viewing though. See More
GPS Navigation & Maps Sygic offers an in app purchase to add on a Heads Up Display for the app. This works for nighttime driving by placing ones device up by the windshield and the device will reflect all information in the windshield for a convenient hands free experience that is on the level of where ones eyes already are.

Offline access has been updated to include search and driving directions in areas that have been downloaded for offline access. However, transit and walking directions are unavailable. The biggest size for any single offline area is 120,000 square kilometers, however, multiple areas can be saved. Offline access isn't available in some regions, however. See More
It's not immediately apparent how to change the language of the maps (of if this is even possible). Thus, it can be troubling/useless if the maps are in the local script (e.g. Korean) and the directions or address someone is looking for is provided in romanized words (or vice versa). See More
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. See More
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. See More
For some reason Google maps are terrible in South America - much worse than OSM maps. Trying to navigate in Argentina from Buenos Aires to Mendoza, it does not work that well. The logical route would be RN7 all the way but Google has gaps in it so it suggests long detours - which aren't necessary. See More
As of Spring 2017, this app doesn't allow you to exit without being nagged to install other apps. If you select "No thanks", you somehow get directed to a Google search page, which is incredibly frustrating. It's acceptable to have a fairly unobtrusive ad at the bottom of a navigation map, but it's definitely a deterrent if every time you exit the app you have to go through a series of annoying screens or take the risk of making a mistake and installing something you actually don't want.

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. See More
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). See More
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. See More
Navmii GPS World (Navfree) uses OSM (OpenStreetMap) data which means it stores the maps on local storage so the user can use the app offline with zero data usage. This is great for those that need to use a navigation app but will have no data connection. See More
Despite having many hidden features, most of them are hidden deep into settings menus or illogical side-menus behind buttons without any explanation. Changing between day and night view usually works automatically, but changing them manually takes 4 or 5 button presses. See More
