The typical to-do list doesn’t really offer much in the way of incentives, other than the incentive to finally be able to toss that scrap of paper in the trash. The Carrot app brings some much-needed ‘tude to your phone in the form of a game; cross off the items on your list and you earn points that can be redeemed for prizes like jokes and gifts, while failing to fulfill your errands loses those points and elicits wiseass remarks like “It’s been hours since you’ve been useful.” Insulting, sure, but still less annoying than a scrap of paper.
