MAPS.ME is a solution for people who seek applications that provide maps without having to be connected to the Internet all the time. Everything contained inside this app is completely free, the maps being provided by the OpenStreetMap service. There are 5 different types of navigation, and you can use each one of them to map your next route.
The attention to detail is very impressive, and you will even find hiking trails and different places that don't show up on maps provided by other sources. You can perform offline searches and navigate using the built-in GPS sensor of your smartphone. You can find airports, restaurants, gas stations, and many other places. The bookmarking feature allows you to save your favorite locations, and you can even share them with your friends and family.
You must remember to turn off your GPS if you're not using the application because you will waste battery life with no benefits. Also, using MAPS.ME, you can make bookings via Booking.com directly from the interface. When it comes to supported countries, this map application has many regions covered.
