4. My Travel (by Tripit)

A nifty little app for you road warriors out there, My Travel lists your current location as well as any upcoming trips you have planned. Built by , a Web-based app that manages itineraries and your various travel plans, the LinkedIn app signs you up for a free account with the service. This app can be especially helpful for your LinkedIn connections who are wondering whether or not you're in town (without having to send you an email or calling you in order to find out).

Once signed up, you can also follow other LinkedIn users who are using the My Travel app. This could be especially helpful if someone you know has a trip planned near wherever your company is headquartered and you want to plan a meeting while they're in town.

If you view business travel as a badge of honor, then check out the stat page. Your Travel Stats, as it's called, will track how many trips you've taken, miles you've traveled, days on the road, as well as cities and countries visited.

The drawback? Maybe you don't want people knowing where you are at all times.
