TripIt's already given its mobile app a sleek overhaul for Apple's iOS and now it's Android's turn. The travel app's been updated to give users of Google-powered devices, including Android Wear enthusiasts, a cleaner layout and more helpful planning options. Now, the jet set can check-in for flights directly from the app, monitor a departures countdown timer, arrange for ground transportation and parking reservations, and even navigate using improved maps. The company's also also added the ability to merge related trips so you can easily keep track of your country-hopping. It's travel 21st century-style and it's available on your wrist.
