One of my all-time favorite applications for Nokia’s Symbian S60 devices is Sports Tracker. It’s a GPS-based tool for tracking your sports activities, with statistics such as distance, speed, time and routes (and even images and videos that you took during your workout) being stored in a training diary online.
I tried to find a similar utility for Windows Mobile, and I came across the strangely titled Run.GPS! Trainer UV. The interface is rather cluttered (like WinMo in general), but the program works pretty well and has lots of advanced features. Check out their site for a full list of features.
Another tool that allows you to use your phone’s GPS for more than navigation is GPSMeter by MASPware. Here’s a quote from the developer’s website:
“Turn your Pocket PC into a high precision metering machine using your GPS receiver! With MASPware GPSmeter you can measure short and long distances (beeline or routelength), altitude differences, areas, timespans, average values and min-max-values using an internal or external GPS receiver.”
Update: SportyPal is another fitness application for WinMo – and it’s free!
