Tripit is actually a very well-known app among travelers. It counts as one of the most popular travel apps because of its ‘secretarial’ services. This app will manage your itineraries better than an assistant. Which means you can save bucks you’d otherwise have used for carrying on an extra human being and instead, you unleashed your mobile device. Tripit will manage every detail of your flight, hotel, car rental, and other activities you have entered. It works with your email so sometimes, it will update your itinerary without troubling you.
