Travelers, meet your new best friend. TripIt takes all the heavy lifting out of travel, giving you a simple centralized place for storing and tracking all your travel info.
Once you sign up for TripIt, all you do is forward every travel-related email -- flight reservations, hotel bookings, even car rental or restaurant confirmations -- to email@example.com. TripIt then extracts the important details and puts them into comprehensive and user-friendly itineraries that are accessible from any phone or tablet (as well as from the Web). It can also sync the data automatically into your Google Calendar, if you want.
TripIt is free; an optional $50/year Pro subscription gets you a variety of advanced premium features.
