Patent US 11,468,388

The present disclosure relates to systems and processes for users of electronic devices to issue physical activity goal challenges and rewards to one another. In one example, a first user can provide a physical activity goal that is to be performed by a second user. The first user can further provide a reward that is to be given to the second user in response to the second user completing the physical activity goal. An electronic device associated with the second user can be used to detect physical activity performed by the second user and to determine whether the second user has completed the physical activity goal. In response to determining that the second user has completed the physical activity goal, the reward can be issued to the second user. The reward can include an image, video, song, electronic message, amount of virtual currency, access to a service, or the like.
