Planning trips can quickly become a disaster. Whether you're traveling alone or with a group, you still have to keep track of plane tickets, hotel reservations, and your basic day-to-day itinerary. The trade off might be worth it, but getting there can sometimes cause a little stress. Fortunately, iOS apps like TripIt can help you manage all of the nitty gritty details and let you focus on what's actually important: the trip itself.
