• It has the map corpus from OpenStreetMap, so one of the best in the world
• It works offline - just download the desired maps onto the device
• That makes it really, really fast. Google Maps is slower
• You can also use it in areas with bad reception. I’m using it for hiking in the woods where there is no cell phone connection available
• I really like the UI - they are f.e. better at displaying house numbers and street names than Google.
• No ads
