Cons
Con Poor response time to recalculate the route
Con No option for satellite/aerial/topographic imagery
Not as useful for navigating while hiking/climbing/etc.
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 No display of speed limit
Neither the next nor the current one.
Con No way to distinguish between fastest, efficient or shortest route
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 Sometimes very strange suggestions
E.g. when not using the suggested route, Maps&Me continues to request to turn even if you are more than 100m after the cross-road.
Con Favorites are a little bit too hidden
Because they are stored in groups.
Con Traffic information is not available in all countries and cities
Source of traffic info is a trade secret this feature is only available to some selected cities.
Con No lane assist
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 Depending on the geographic location OSM may have the most detailed maps or the most bare/outdated map.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 Does not show images offline
Does not show images offline if supplied in standard kmz file. i.e. zipped kml plus image folder.
Con No tourist detail maps
Con Single resolution only
It can only navigate one image at a time, so if you save an online map for offline use, it will only ever display that particular zoom level, you cannot zoom in or out to see more detail or wider view.
Con Some bugs with map display
Sometimes it will say "Google Satellite" for instance, but is actually showing a regular "Google Road" map, and you have to change it twice to get it to actually change.
Con Photo storage folder isn't customizable
Photos have to be in a particular folder to show up as icons on the map. If you have your camera app save to a different folder, they won't be noticed by Maprika.
Con No folders for placemarks
My Places is just one big collection, with no ability to distinguish types of places or show only certain types at a time.
