Do NOT download this app!
I downloaded this app to use in connection with my London Pass for an upcoming trip. Within hours my phone went from fully charged to empty. After 3 days and a trip to the Apple Store, both my iPhone and iPad had to be restored to the factory default.
Downloaded this app in front of the apple representative and just watched the battery drain over an hour. Another restore and no download of this app and everything was fine... BEWARE!
