Agreed 100%. I don't use it to track weight, but being "Fitbit shamed" when I don't hit 10,000 steps per day is a strong motivator. More athletically speaking

Agreed 100%. I don't use it to track weight, but being "Fitbit shamed" when I don't hit 10,000 steps per day is a strong motivator. More athletically speaking, so is missing workouts and thereby kudos from my friends & followers on Strava & Garmin Connect. On days when I really just don't feel like running, this makes the difference between getting out of the house and wasting more time on the innerweb.
