Today I'm pleased to announce the new My Tracks application for Android-powered phones such as the T-Mobile G1. My Tracks records tracks of outdoor activities using the phone's built-in GPS. It shows these tracks on a map and presents live statistics, including an elevation profile. And here's the best part: it lets you easily share your activities with friends and the world using Google Maps, as well as archive your training history with Google Docs.

Many GPS receivers require you to plug a separate device into a computer, install software, transfer, convert and upload your track to the web. With My Tracks, this has become a whole lot simpler. I no longer need to carry multiple devices when I go out for a ride, and I can easily share my rides on the spot with anyone I'd like by recording and uploading my track right from my phone and then sharing it out via email or even Twitter.

Here's a look at some of the things you can do with My Tracks:
  • Record and visualize GPS tracks while running, hiking, biking, skiing — or any other outdoor activity
  • Get live statistics, such as total/moving time, (average) speed, distance, and elevation profile
  • Send performance statistics to Google Docs to build a training history
  • Mark places and describe activities for others to discover via Google Maps
It's simple to get started. Just go to Android Market on your Android-powered phone and search for "My Tracks." Install the application and hit "Start recording" from the menu. This video shows you how it's done:

My Tracks was developed as a 20% project. On behalf of the entire team, we hope you enjoy using this application as much as we had fun developing it. And we're looking forward to seeing all of the creative ways people use it.
