And the only app for your garmin. From here you can upload to strava, endomondo, mapmyfitness, etc., which then uploads to the National Bike Challenge. It syncs okay with my fitness pal for calories/good balance (although the software isnt great on the garmin side). Hardware is Garmins specialty! Software is not. If you have an issue, call--dont email. Call staff is f^*%}ing awesome. Email online? Never satisfied with that support--they will ask you questions and in the end their response always seems the same (hard restart). Nope.
