Ariadne GPS
There are hundreds of gps apps. Do we really need one more?
Ariadne GPS is more than a simple gps app.
Besides offering you the possibility to know your position and to get information about the street, the number, etc. it also lets you explore the map of what's around you.
What do we mean by saying "explore"? You'll deal with a talking map. If you have VoiceOver activated on your device, you will be able to know the street names and numbers that are around you by touching them.
Just put your finger on the screen of your device, when showing the map and moving it you will be told the info's about the street you're touching.
Your position is on the center of the screen. What's in front of you is on the top half of the screen and things behind you are on the bottom half of the screen.
