The app seems to go through all of my contacts every time a select a new location, so its really really slow. And even if I ask again from the same location it repeats the search/mapping process. Also a few glitches on the first use, like when it goes through the initial mapping process, then asks to use current location, then forgets what it has mapped and starts all over again. Also had a hard time with entering a city as a location, as opposed to current location. Said that it couldnt find Santa Monica CA.
