Web Exclusive: Smart Apps
These clever smartphone programs make your travels easier
BY ADAM BAER

Warm up to the word “app.” Smartphone “applications,” which range from serious to silly, have quickly become indispensable—especially for travelers. A bevy of travel apps (and not just for the iPhone) can help you track your flights, find cheap gas and more. Here are some of our favorites.

FlightView
Don’t drive to the airport until you absolutely must. With this app, you can enter the details of your upcoming flight and receive alerts whenever the status changes. You also get an “airport delay map” that shows lags across the U.S. and Canada as well as current weather conditions. flightview.com; $5 for Blackberry and Palm; iPhone users should opt for FlightTrack Pro ($10), found at mobiata.com
 
The Weather Channel Max
An original take on weather apps, this one tracks your GPS location and gives you interactive maps that you can customize with layers devoted to radar, clouds, temperature and rainfall. You also get long- and short-term forecasts, some as videos from The Weather Channel’s on-air talent. weather.com/mobile; $4 for iPhone
 
Tether
With this app, your laptop can connect to the Internet via your phone's signal. That means no more hunting (or paying) for WiFi service; you just need to be in an area with cellular coverage. tether.com; $50 for Blackberry
 
WorldMate Live
Want to convert a foreign currency using up-to-the-moment exchange rates? How about storing and organizing your itinerary as well, all with an app that doesn’t cost a thing? worldmate.com; free for Blackberry, iPhone, Nokia and Windows Mobile
 
Voice on the Go
If you can’t type in your car, that’s probably a good thing—and this app supports it. Use voice commands to send emails and text messages from your phone, and to listen to, compose, reply to, forward and delete emails. And check Facebook and Twitter. voiceonthego.com; $6 for all smartphones
 
Cheap Gas!
You’ll save even more on your road trips by downloading this free app, which steers you to the least-expensive gas stations close to your car’s current location. apple.com; free for iPhone
 
Navigon MobileNavigator
The MobileNavigator is considered the best app for turning an iPhone into a GPS navigation system, with realistic renderings of roadways (think asphalt, road markings and signs) as well as a feature that lets you know if you need to change lanes for your next turn. navigon.com; $90 for iPhone and Windows Mobil; a version for Google Android is in the works
 
SitOrSquat
They joked about it on Curb Your Enthusiasm, but it really exists: an app that finds (and even rates) the nearest available public bathroom, based on your GPS location, zip code or address. Hey, we all have needs. sitorsquat.com; free for Blackberry and iPhone
 
Layar
This next-gen app pulls info off the web and lays it on top of the live picture from your phone’s camera. Let's say you're standing across from the Empire State Building: Pan up, and a Wikipedia entry might appear. Click on it to find out when the skyscraper was built. Or pan down the block and click on the Yelp! restaurant review to find out what you should order for lunch—or not. Technologists call this augmented reality; we call it the future. layar.com; free for Google Android
