There are loads of reasons to use a smartphone - but one of the best is to get from A to B. Android really has that sewn up for the basics, but there's loads more to be gained from having a quick run through the Google Play Store.
So check out our rundown of the best apps to get where you want to go, see the best things or explore the night sky.

NavfreeDownload from Google Play
This open-source satnav lets you download route maps before you start a journey, so you don't need a data connection once you're on the road, something that still trumps Google Maps. Its various routing options including walking routes, and automatic redirection whenever you take a wrong turn.

Soviet Military Maps FreeDownload from Google Play
This app delivers exactly what it says: cold war topography from behind the iron curtain.

A modern take on the treasure map, the official app of Geocaching.com includes coordinates for close to two million hidden containers around the world, with options to sort by difficulty or location. A great way to discover this GPS-based hobby.
