ExerciseUp is a Chrome Extension that allows parents to limit their children's internet activity until they have exercised. It interfaces with the Jawbone UP to allow a parent to set a minimum amount of exercise that each child must do daily before getting access to the internet.
There is an options page where the parent can see a report of all of their children's activity, and children must authenticate with their Jawbone accounts to unlock the internet each day. When a user authenticates with their Jawbone account, they will either get a message that tells them they have to exercise more, or the internet will be unlocked if they have already done enough exercise. The parent can set an admin password that lets them bypass the lock.
