Adda Steg is an app with different step challenges. Challenges that are created by companies that want to raise the need for movement in everyday life.
A challenge that is created has a different level of difficulty to complete, in terms of the number of steps that need to be completed per day. If you succeed in reaching the goal one day, you will complete a sub-challenge. When you have completed the amount of sub-goals needed to complete a challenge, within the challenge's time period, you will receive an email with any prize/offer.
