Ever wanted to use a real life working Tricorder from the Star Trek: The next generation TV series? Now you can! This app is confirmed(by me) to work perfectly on the Pocket eDGe, haven't tested it on the full-size eDGe. It basically turns your eDGe into a full size Tricorder with many fun and geeky features to show off to your friends at a Star Trek convention. Unfortunately, some of the features do not work, such as the compass or the accelerometer modes. Only the WiFi works in the EMS scanner(eDGe lacks 3G radio to scan that).

The APK is in the Downloads link on this page, no market access required.

If you have an Android cell phone, all the features should work(despite a smaller screen).
