We've scoured the market and tested hundreds of travel apps to come up with the ultimate tool kit for the vacation-bound. Best of all, we're not stopping here. We'll be relentlessly evaluating the new arrivals across platforms (iPhone, iPad, Android, and BlackBerry) and regularly updating this list with our favorite travel apps—leaving you the time to, well, actually travel.
FIND A FLIGHT Kayak's website set the standard for streamlined searching, and its app delivers the same ease of use on the go.

MAKE THE MOST OF A LAYOVER Consider it Yelp for airports. GateGuru's app contains searchable directories for 98 U.S. airports (124 airports overall) and more than 25 international hubs.

Free. Download it: iPhone/iPad.
RAFT A CONTINGENCY PLAN For the frequent flier who has no time for snafus, FlightTrack Pro is an essential aid.

If your flight is canceled or delayed, it's easy to search for other connections while you're standing in line for the gate agent or even from 30,000 feet—you can access the app's route-maps feature offline when you're in the air. iPhone, iPad (FlightTrack Pro), $10; Android, Blackberry (FlightTrack), $5. Download it: Android, BlackBerry, iPhone/iPad.
KILL TIME ON THE FLIGHT The perfect nervous-passenger distraction, Flight Control HD for iPad gives folks something to focus on while surviving a long-haul flight: an air-traffic-control strategy game that lets you manage planes' flight patterns by dragging them along the touch screen. If only getting to your real-world destination were so easy. iPhone (Flight Control), $1; Android, BlackBerry (Flight Control), $3; iPad (Flight Control HD), $5. Download it: Android, BlackBerry, iPhone, iPad.
OMPARISON SHOP With thousands of user-generated reviews of hotels, restaurants, and attractions worldwide, TripAdvisor has long been a mother lode of unvarnished assessments.

Download it: Android,iPhone/iPad.
SCORE A CHEAP ROOM If landing a rock-bottom rate ranks higher than remaining in complete control over where you stay, roll the dice with Priceline Hotel Negotiator app. You choose a preferred star rating and an ideal price (recent successful bids in the area are listed as a guide), and the tool will lock in a room that meets your criteria. Bonus: The app uses GPS, which is priceless for lining up convenient last-minute accommodations for unexpected overnighters. Free. Download it: Android, iPhone/iPad.
GET A BIRD'S-EYE VIEW You've probably already used Google Earth's satellite images to zoom in on your childhood home or your current residence—in almost scary detail—but the intuitive app also serves as an easy way to suss out a hotel's rooftop pool deck or the size and location of various parking lots at a big museum or other attraction. Free. Download it: Android , iPhone/iPad.
FIND THE RIGHT SHIP With more than 12,000 itineraries on 20 cruise lines, the new Cruise Finder app by iCruise.com has one of the largest listings databases out there—plus plenty of other features to smooth your sailings.

SET A BUDGET It's easy to lose track of all the scattershot incidental costs that add up over the course of a cruise.

Even kids too young to grasp the game will get a kick out of tapping the icons and shaking the screen clear. Android, $1; iPhone, iPad, $2. Download it: Android, iPhone/iPad.

SCREAM FOR ICE CREAM First, give yourself some elbow room. Then fire up Scoops, a highly addictive game even a technophobe could master.

Free. Download it: iPhone/iPad.
SNIFF OUT CRITICS' FAVORITES If you're more interested in getting a recommendation on the spot, download Urbanspoon.

Refresh with a simple shake of the device, or click off for critics' reviews and some menus. Free. Download it: Android, iPhone/iPad.
MAKE RESERVATIONS Instead of calling 12 restaurants to find one that can seat your party of four, let OpenTable do the work. Search more than 15,000 restaurants in Canada, the U.K., Mexico, and the U.S. by the number of diners and your desired reservation time, and then sort by cuisine, price range, and neighborhood.

ASK THE EXPERTS Crowd-sourced restaurant reviews on Urbanspoon or Yelp can be telling, but you never really know who's behind them. The owner's mom? A foodie fussbudget? LocalEats relies on (relatively) objective parties-food bloggers, newspaper dining critics, alt-weekly columnists-to compile its top-100 lists in America's 50 largest cities. Locally owned spots are in, national chains are out, ensuring you'll find an authentic meal-without too much legwork. Android, iPhone/iPad, $1; BlackBerry, $3.

EXCHANGE AND TRANSLATION
PAY THE RIGHT PRICE There are dozens of free currency-converter apps, but Oanda Currency Converter stands above them all for its reliability and depth of data.

For even greater accuracy, the app also adjusts results to reflect the specific transaction type (credit card or cash) you select. Free. Download it: Android, BlackBerry, iPhone/iPad.
SPEAK LIKE A LOCAL Foreign-language mix-ups can make for some serious travel stress. The app iTranslate—basically a digital phrase book—comes to the rescue. It includes 52 languages and translates faster than you can say, "Huh?" Just type in the perplexing phrase and iTranslate displays it back in your language of choice. (The app requires Internet access, but you can store key phrases for future Wi-Fi-free reference.) Free. Download it: Android, iPhone/iPad.
SNAG THE CORRECT SIZE Clothing size is unreliable from label to label—and country to country. Now men and women can shop with confidence by using Convert Clothes.

Whether anything will actually fit is another story. Free. Download it: iPhone/iPad.
CONVERT ANY MEASUREMENT Traveling can seem like one long equation, from figuring out temperature (Celsius?) to assessing how much gas is left in your tank (liters?). Conversion-catchall Convertbot does the math for you. Spin a wheel to select one of 20 categories—time, speed, even data download size—then type in the amount. The app instantly converts the figure into the desired unit of measure. You'll never go over the baggage limit in a foreign country again. $2. Download it: iPhone/iPad.

FIND THE PERFECT PHRASE Overcome awkward lost-in-translation moments with World Nomads. The 25-language translator apps cover keywords such as please and thank you, numbers up to 10, and a few phrases useful for other travel conundrums (our favorite: "Those drugs aren't mine!") in easy-to-scan categories like Introductions and Travel Health. Most phrases have audio clips. Free. Download it: iPhone/iPad (downloadable in 25 languages, including French, Spanish, German, and Italian).
PHOTOS AND VIDEOS
EDIT IMAGES A few tweaks can turn even the most drab camera-phone images into frame-worthy photographs. Use Photogene to add backgrounds and colorful borders, crop out unflattering details, or just remove red-eye from that otherwise-flawless family portrait in front of the Eiffel Tower. iPhone, $2; iPad, $3. Download it: iPhone, iPad.
ORGANIZE AND SHARE With Photobucket, you can sort your vacation photos before you've even boarded the flight home.

Download it: Android, BlackBerry, iPhone/iPad.
INCORPORATE SOUND These days, the old vacation postcard doesn't quite cut it. Fotobabble lets you express a more unique sentiment: Just snap a photo, record your own audio message (up to one minute long), and send the file to a friend's e-mail account. Free. Download it: iPhone/iPad.
ADD A RETRO FEEL Looking to enhance your images with a little old-school flair? Hipstamatic, an app based on the discontinued 1982 camera of the same name, has nine options that add artful blurring, fading, and flashes to your photos to create that vintage-snapshot look. $2. Download it: iPhone.
SHED SOME LIGHT For all their strengths, many older-generation iPhones lack one important element: a flash. The Camera Flash+ app solves that problem, with a self-adjusting burst of light that allows users to take vivid, point-and-shoot-quality photos long after the sun has set. Free. Download it: iPhone.
TAKE THE LONG VIEW Some scenes are simply too majestic to capture on one screen. Enter Pano, which stitches together up to 16 separate shots to take in, say, a 360-degree view of the Grand Canyon. A built-in guide helps you line up each frame, and the app will hold your place if a call interrupts your shoot. $2. Download it: iPhone/iPad.
SEND A PERSONALIZED POSTCARD Nothing says "Wish you were here" like a good old-fashioned postcard—with your face smack in the center. For about $1.50 per note, HazelMail turns your photo into an actual paper card complete with a custom message and then stamps it and sends it off within about two business days, saving you the trouble of hunting down a local post office. Free. Download it: BlackBerry, iPhone/iPad.
DOCUMENT YOUR ADVENTURES It may have been invented for students, but Facebook's ubiquitous app has become an invaluable tool for all kinds of folks.
