AllSportGPS turns your mobile phone into a performance monitor by measuring time, distance, speed and calories burned. You also get route traces and weekly statistics so you can track just how well you’re doing on your drive to out-do Lance – Fittest Man in the Universe – Armstrong. $20.00 for the basic product and $6.99 for the web enabled premium versions.
You can also record lap times and get an audible alert based on time or distance. You can even race against previously recorded workouts – AllSport shows your time difference ahead or behind, and it shows your position compared to your virtual competitor on the map screen. AllSport GPS Silver is powerful, but you don’t need to buy any special hardware. You don’t need to carry another device. And you don’t need to charge another battery.
