Here are my top ten favorite general travel apps for 2014. I use all these apps personally in travel planning, and/or while away.
10. White Noise — ($1.99: iOS, Android Windows 8) Too much noise coming from outside your room, or even inside it, possibly from another room, a dripping faucet, or a roommate? White Noise can rescue you. The “white noise” it makes can help most travelers get to and stay asleep by blocking distractions. I use the built-in “air conditioner” sound. White Noise also has a built-in clock display which shows through the night, and you can setup alarms to wake you as needed.
