Fourth of July travel plans may mean long airport lines and gridlock traffic, but this year we're making our journeys as painless as possible with the help of these new travel-friendly and time-saving apps:

Gas Buddy Never pay more than you need to for gas thanks to this free app for all mobile platforms. Plug in a zip code for a list of nearby gas stations and their corresponding (and regularly updated) fuel prices.

TripIt Instead of searching your email for reservation numbers and travel times, use this website and mobile app (available for most platforms) to keep all your vacation information in one place. Forward confirmation emails (flight, hotel, rental car, scuba tour, etc.) to your free account and TripIt creates an easy-to-read trip itinerary.

FlightBoard While there's no shortage of ways to check your plane's status, we've found FlightBoard ($4 for Android and iPhone) to be the most reliable option. Check the actual arrival and departure boards of more than 4,000 airports for up-to-the-second info on delays, gate changes and the like.

AllSubway Planning to navigate a new city via subway? Pull up worldwide underground maps (of everywhere from Berlin to Tokyo to Baltimore) right on your iPhone or iPad with this new app ($1), and stop worrying about unruly folding maps or out-of-date signage.
