When running, do you have to have your phone with you too?
In other words, does phone need to be in close proximity? Purchased a Pebble SmartWatch tonight at Target but it syncs with phone and you have to run with phone and watch. Trying to find a solution where the phone is not needed for running.
You can leave your phone at home! The TomTom Spark has GPS, music, and heart rate monitor. I sync all data with my phone afterwards. You can set up to automatically upload to other apps, as well (e.g., Strava, MapMyRun, etc).
