You can stand in line to get tickets for a trolley tour, whale watch, or museum visit. Or you can power up your iPhone, buy tickets with a few clicks, then flash the confirmation page on your phone to get in the door.
The Greater Boston Convention & Visitors Bureau has released the BostonUSA app, a 99-cent electronic application that lets you purchase tickets for tours and attractions, search for current events and activities, and track down deals without leaving your home or hotel room.
Thanks to the GPS-based Map It function, you can easily find your way to each venue or point of interest. 888-733-2678, www.bostonusa.com
