Google Trips is a comprehensive mobile travel app, but you can't get it yet.

Google is working on Trips, a travel app that scours your Gmail account for travel-related info and lets you plan and book your trip, all from your mobile phone. 

The app is currently in testing, and is available as beta only to some members of Google's Local Guides program, as reported by Dutch site Android World, which grabbed a bunch of screenshots of the app. 

Even though it's still in beta testing phase (we've contacted Google about the app, but have not yet heard from them), Trips seems to be very comprehensive. It grabs travel information, such as flight reservations, from Gmail, but it also lets you build an itinerary manually. Then, it presents you with a complete overview of your trip, including reservations, info on places to see, restaurants and public transportation. 

Even better, it's all available offline, so you can browse through your trip info without an Internet connection. 

There's no word on when the app might be released to a wider audience. 

Just last month, Google launched Destinations, a service that lets you do almost all of the above without an app — directly from your search results. And the company already offers a variety of other travel-related services, including Flights. Perhaps it's time to roll all that up into one app.
