Ranked in these QuestionsQuestion Ranking
Pro Obtains data from community-based OpenStreetMap
MAPS.ME uses data from OpenStreetMap, meaning the data retrieved from that service is a community-based map. Anyone can freely edit and contribute to the map, a map concept that is similar to Wikipedia.
Pro Includes offline routing and turn-by-turn navigation
Users without a data connection can still use the app for turn by turn directions, which is great for those that travel or use a device that does not have a cellular data connection.
Pro Fast rendering
By using compression of the map data, MAPS.ME is able to speed up the rendering of their maps to one's device. This allows for a quicker feeling app.
Pro Matching modern material-like interface
The design of the app uses a material-like interface making for a close to native looking experience on Android.
Pro Very detailed selection of areas to download
That saves a lot of download, e.g. from ~500MB in other applications it is reduced to ~50MB for German surroundings.
Pro Optionally can download traffic information
And showing it color-coded (Google-maps-like) on the streets.
Pro Easy adding/editing of bookmarks/favorite places
Click on the map and you will have the option to Bookmark, Route From, Route To. Having selected Bookmark simply offers to edit it, e.g. give it a different name.
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 Depending on the geographic location OSM may have the most detailed maps or the most bare/outdated map.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 Very slow search and route calculation
Probably because MAPS.ME has more POIs in its database which ends up with all searches and route calculations being very slow.
Con Very limited options
E.g. no way to hide certain buttons like the traffic button, or to configure the language used to display city names.
Con No way to distinguish between fastest, efficient or shortest route
Con Does not show images offline
Does not show images offline if supplied in standard kmz file. i.e. zipped kml plus image folder.
