I currenlty use a ipone and strava to track all my rides. Any advantage to using a Garmin?
Capabilities depend on the app. There are enough apps out there that you can do all of those things with your data, but depending on the app, not all on the same app. Definitely when you factor additional sensors into the equation (phones are compatible with many sensors, but they may require different sensors than you use with your Garmin).never used my stupidphone as a GPS. haven't really looked into the available apps since I do have a GPS. can you save/view/edit your data like a GPS?
HR? Cadence? speed sensor? virtual partner? tracks? waypoints? routes?
I bought my Edge when all I had was a real cell phone. I love it. Didn't get a stupidphone until I moved and can no longer get TV/Internet.
but the clincher on cell vs GPS is cell service. Too many awesome trails where there is NO cell service.
