This app lets you create a family and invite all household members. The family can then share shoppinglists to easily synchronise what to buy when at the groceries. Create missions and rewards to keep kids doing their chores. Each chore (called a "mission") can be completed by the child and approved by the parent, and when approved will give the child a number of points. These points can then be used to request a purchase of a reward, created by the parent.
