This is a brilliant and simple idea brought forward in an elegant and easy to use app. I love the quick car park feature, and the ability to store many anchors to places Ive been is great.
Only two things would make it 5 stars. Allow adding anchors by map coordinates/address, not just current location, and allowing the Meet Friend feature to be used without Facebook. I understand these two improvements are coming though.
