Mobile devices can be used to improve productivity and are essential for keeping you in touch with your business contacts, but you can also use them for entertainment and now for helping manage your daily fitness regime. I was checking out my RSS feeds and saw that All About Symbian posted on the new free Nokia Sports Tracker application suite. Nokia has a similar application in their 5000 Sport device and now are offering it for free to owners of the latest Nokia S60 3rd Edition devices, including most of the Nseries and Eseries models. The Nokia Sport Tracker software allows you to connect your mobile device to a GPS receiver and use it to record location-based data. Speed, distance, and time are stored automatically to your training diary and you can then export your excercise route to Google Earth. The Nokia E-series blog has more details on the application and its usage. I just went running with a Nokia N91 with Yahoo! Music mounted in an OtterBox iPod Shuffle armband and now will have to find a way to strap on a Bluetooth GPS receiver too and see how this all works together. Thanks to the Nokia research team for making this available as a free download.
