[qi:gigaom_icon_google-android] TripIt, a travel aggregation service that is offered as an application on the iPhone and BlackBerry, is now available as a beta app for Google’s (s goog) Android platform and can be downloaded from the Android Market. Just like us, our colleagues at jkOnTheRun, WebWorkerDaily and TheAppleBlog are all fans of TripIt, and the Android version will allow more people to use this fantastic service. TripIt recently launched an application programming interface for other developers to build their own web and mobile apps.
