As the title suggests, we try to apply gamification for people trying to lose weight. We use a points system similar to Weight Watchers, except in reverse (the more healthy the food, the more points).

Some people have commented we're similar to another site: Fitocracy (their app also is out today). But we're reaching a different audience: people who want to lose weight or live healthy, but don't know how/where to start. We offer 7-30 day challenges that help people build long-term habits such as "quit soda for a week". The point is to break down the abstract goal of being healthy to smaller subgoals, and winnable games.

We're also working on providing concrete, personalized advice based on your activity too. Tracking and gamification are nice, but it's useless without actionable advice.
