A mobile trip itinerary planner popular with business travelers.
Available for: Android, BlackBerry, iPhone, iPad, and Windows Phone.
What it does: WorldMate helps you plan, book, and manage your trips. You'll be notified of delays and cancellations; you get a currency converter, a tip calculator, weather reports, and info on local restaurants, businesses, and more; and you can connect with your LinkedIn friends.
Cost: Free / $9.99 (upgrade to Gold)
What's hot: The iPhone is just now getting the cool hotel booking feature that WorldMate's Android app has. (The iPad will have to wait until the next update.) You can make same-day hotel reservations and get a deal on that room rate, and there are more hotel options than on Hotel Tonight, my usual last-minute booking app, although Hotel Tonight offered better room rates on the same hotels. It's valuable to be able to add a meeting to your itinerary and connect with LinkedIn colleagues.
