Ranked in these QuestionsQuestion Ranking
Pro Crowd sourced traffic information and reporting
Pro Convenient offline support
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.
Pro Works good for hands free navigation
Navmii GPS World (Navfree) has voice guided navigation for its maps, even offline so users do not need to mess around with the app while driving, which is safer than having to constantly look at ones device.
Pro Fast map rendering
Pro Very detailed official local maps
Supports official maps published by park services, etc, which often have more details than any other map available.
Pro Save placemarks
Pro Records GPS tracks
Con Sometimed strange detours before reaching your destination, even at short distances.
Con Quality of images not the best
The quality of images in the app are sometimes not the best . It is caused by some form of conversion, which may save room but limits the apps looks.
Con Cannot use SD card
Even though the maps are free of charge and some of them are official park maps without copyright issues, the app still refuses to store them on the SD card, so the map storage tends to take up far more internal flash memory than any other app.
Con Map search is awful
Searching for map files is very frustrating as the map search only shows the center point of each map as a pin, so you can't see whether the map includes a point you're interested in, and since there are usually many historical maps of the same location, they produce many pins appearing on top of each other. You have to download each one and open it in order to see what it will look like, rather than previewing them in the live display. Good overview maps will appear as pins in random locations, while there will be tons of topo map tiles everywhere else
Con Only shows one map at a time
It supports USGS topo maps, for instance, but if you walk off the edge of one, you have to manually load the adjacent map, which is a hassle. It would be nice if, like other apps, you could select "USGS topo" as the map source, and it would automatically show whichever specific map your location is currently near the middle of (since the USGS maps have margins and legends, etc.)
Con Only supports local maps
You need to plan ahead and download a map for each park or region you're going to visit before you go offline.
