It unlocks a fun fact whenever your children achieve their 60-minute daily play goal, for instance. Your kids will also earn coins for every task you assign, which they can then use to redeem (pre-approved!) in-app rewards. In case your offsprings are procrastinators who can barely be motivated by virtual coins, though, you can also set a timer on their bands to make sure they don't keep putting off their chores till later. If you don't mind dropping $80/£80 for something that looks much, much better than that free tracker McDonald's bundled with its Happy Meals, check out your local Target, Best Buy, Toys R Us, Walmart and other electronics retailers.
