Name: Airport Transit Guide, by Salk International
Available for: iPhone and iPad. Blackberry and Android versions are planned later this year.
What it does: Provides up-to-date ground-transport information for 460 airports around the world. This app replaces the well-respected print edition in publication since 1982.
Cost: $9.99; free “Lite” version with two sample cities (Denver and Hong Kong)
What’s hot: You’ll find links to websites and two-click access to phone numbers. Guidance on route, cost and timing is thorough.
What’s not: There are no bells and whistles and little interactivity.
Worth it: It’s a steep price for an app. But if you are a frequent flier or business traveler, or taking a multi-stop journey around the world, it’s indispensable.
