CardioTrainer was one of the first apps I downloaded when I got my G1. If you’re the outdoorsy type, it should serve your needs quite well, whether you’re a cyclist, runner, hiker or just want to track your daily walks. The application is easy to use. Launching it calls up a start screen, and pushing the “Start” button gets the timer and GPS tracker started. Just tuck the phone away and go about your business. One thing to note: Make sure your phone’s GPS has a lock on your position before setting off, otherwise, CardioTrainer might not track your position.
