Is there an app where kids earn screen time for doing chores?
Yes, and they come in two shapes. Minutes-bank apps pay out screen time per completed chore, which the child then spends. Deadline apps like taskr skip the currency entirely: apps stay available and lock when a chore passes its due time, unlocking when you approve a photo of the finished chore. Both connect chores to screen access; they just disagree on whether screen time should be a balance or a default.
