Collective Weight

Log your weigh-in in seconds and watch the pounds come off on a clean, zoomable trend chart. See your total lost, your streak, your projected goal date, and exactly how far you have to go. Then make it interesting: start a challenge with friends, family, or coworkers and see who can drop the most body weight. WHY YOU'LL ACTUALLY STICK WITH IT • Friends keep you honest.
