If you don’t have an iPhone or app-friendly mobile device, we apologize in advance for sharing Frommer’s excellent presentation of iPhone Travel Apps: Essential Downloads. You already know there’s an app for everything, so don’t book a flight without installing a few of these first.
One of the Web’s most popular travel review websites has made its way to the iPhone. This Web-based app pairs your GPS coordinates with content from the TripAdvisor website, so you’ll need a data connection to use it. You can see ratings, read reviews and book hotels directly from the app, making it an excellent resource for last-minute planners.
Just as its name implies, OffMaps allows you to download maps to your iPhone for offline use, so you can find your way around without racking up international data usage charges. The app costs $1.99, but includes two Guide credits, for downloading city-specific travel listings and maps. International listings are somewhat limited at this time, but the app can still pay for itself in a day, considering how much you’ll save on data usage.
After creating an account on TripIt.com, simply forward your flight, hotel, or rental car confirmation emails to email@example.com, and essential travel details will be stored online. Use the iPhone app to access all your trip info on the go, including flight status info. All for free. Trip details are saved on your device, so you only need a data connection to synchronize updates.
