Apps for easier trips
RoadNinja tracks your location and lets you know the price of gas at stations at upcoming exits. It also lets you know what's at exits in the opposite direction, in case gas is cheaper going that way. The app also will tell you which restaurants, shops, and other attractions are just down the road. Also, try the INRIX app, which offers just about everything a commuter or road warrior might want. There's traffic news and a traffic map. When I set my location, I also got screenshots from traffic cameras. With one click, you can text or e-mail your arrival time to family and friends. The app will note construction or congestion with small icons along your planned route.
The free version of Flight Tracker operates much the same as FlightAware. Put in your flight information, and it will tell you the type of aircraft you'll be flying, advise you of delays, and tell you the gate from which you'll depart. It also gives you a weather forecast for your destination.
