En español | These days the cellphone feature on your smartphone is almost an afterthought: Now that gadget in your pocket can also pay your bills, bring you world news and let you video-chat with your daughter (finally, something from The Jetsons came true!).

Savings on car rentals, cruises, hotels, flights, and more.


Like all road warriors, I have a toolbox of apps on my smartphone that has made traveling much, much easier (although I'd really appreciate an app that would keep it from falling into the toilet). Thanks to these apps I can make more informed decisions, find the information I need when things go wrong, and generally enjoy peace of mind when I'm away from home.


Need a quick snack during your layover but you're not sure what the best options are? GateGuru is a worldwide airport guide to restaurants, cafes, shops and even free Wi-Fi. There are also ratings and reviews to help cut down decision-making time. (Why grab a bag of trail mix when you know there's a Shake Shack six shops down?) Along with takeoff and arrival information, the app provides estimated TSA wait times for your various checkpoints.


Most airline websites show you a seating layout for their planes. But on SeatGuru — a website with a mobile app — you can find seating plans for more than 700 types of aircraft, and those seats are color-coded red, green and yellow for comfort and convenience. You can look at the charts on SeatGuru to evaluate specific seats for your flight on your airline's site. Obviously, you don't want to choose a red seat, it might not recline, or it may have no window. Other seats might be near a busy galley, which is a real hassle on a long-haul flight. Now, if only SeatGuru could help me avoid seatmates like the guy who felt both armrests were his birthright, or that Ludwig Von Businessman who pounded away on his laptop keyboard as if he were performing at Carnegie Hall.


You know you can't bring a firearm or a full-size bottle of shampoo on board, but how about a golf club or jar of homemade jam? Type any item you're unsure of into the "Can I bring my…" space to find out. Put the My TSA app on your phone and you just might spare yourself from kneeling on the airport floor, repacking your non-carry-on items. There's also a traveler's guide with rules regarding passengers with special medical needs.

Sleep Pillow (available for Apple products only)

Lots of "white noise" apps do a good job of lulling you to sleep in a hotel or on a plane, but this one offers especially authentic sound effects. For instance Sleep Pillow doesn't simply offer you "rain," but hard rain, soft rain, rain on leaves, rain on a tent, and my favorite: rain on a car with the metronomic tick of the windshield wipers in the background. Other sound categories include ocean and weather, and you can layer sounds for your own unique mix. Right now my compilation is "Rain on Car" followed by "Train in the Distance" and finally "Soft Wind Chimes." I never make it to the chimes.
