Name: Triposo.com

What it does: It's a global destination database that lets you download maps, travel information, and recommendations on more than 150,000 destinations in 200 countries and use them offline.

What's hot: I've never experienced such a quick place-by-place download option from an app. Download your guide and then turn the pages like a magazine, or delve right into practical info in "Things to Do," where you'll find Yelp reviews, WikiTravel descriptions, and practical info such as hospitals and grocery stores. Build your own guidebook portal and bookmark your favorite restaurants, museums, and more so you can return to your personal section later.

What's not: I was a little hesitant to use the hotel-booking process. There was so much info to fill in; I didn't feel it was user-friendly.
