Users participate and compete in various public and private leagues and challenges on Fitrockr.
A league works similar to a Football/Soccer league. During a season (month or week), users collect activity points, steps or miles/km via fitness activities to improve their ranking. At the end of each season, top athletes are promoted to a higher division.
The division system ensures fair competition as users with comparable activity levels are automatically grouped in divisions which ultimately increases motivation to be more active.
