We just published a new app to the Marketplace, called Mobile Speedo it turns your phone into a speedometer, direction and route mapping device.

There's a quick description of Mobile Speedo here.

In simple terms, if you have a Windows Phone, Mobile Speedo allows you discover your current location, direction and speed, and then share that information. So a bit like foursquare but for people who are going places ;-)

You can share with your followers on Twitter, or by SMS or email. Needless to say, you should be a passenger, not the driver if you are going to do this!

You can also map your current location and save routes. I will be giving this feature a tryout on the mountain bike at the weekend.

A technical exercise in exploring the use of GPS, cell tower data and compass info, Mobile Speedo was created by the Metia Labs team.

While using it for car journeys springs to mind first, the train commuters in the team have enjoyed using it to check their rate of progress (or not) into Waterloo each morning.

The Labs team went the final yard to make sure it looked good on the latest generation of Windows Phones and then released it to the Marketplace, to see what others think of it. If you give a try, please pass your feedback along via comments here, or a review on the Marketplace.

Some examples of the great looking screens below:
