Its a very good app although it has some trouble with identifying my location (even using wifi), but the giant pulsating "you are here" button is extremely distracting and makes me feel very seasick and nauseated. I have to cover it with my finger as I look at the map or it gives me a headache- it would be much better as a smaller, NON-MOVING point (or perhaps even pulsating occasionally rather than constantly and quickly).
