The new “my tracks” app looks really cool! I have been using the app CardioTrainer for a couple months and then sharing by exporting into my maps (CT provides an exportable kml that you can send to my maps — same place as my tracks). Just wondering if anybody has used both apps? …I feel like CardioTrainer is more for actual training and my tracks is just a GREAT standard gps tracking app. They're both in the Lifestyles section of the market. What do you think?!

here's a link to the CardioTrainer page incase you want to give that a try too!
