Give your mundane tasks the trappings of an RPG, rewarding an animated avatar with experience points and gold for completing "quests." There's no actual gameplay involved, but watching your avatar beat the task's description into submission is way more fun than just ticking a check box.
WIRED Well-designed RPG-like animation and Game of Thrones-worthy background music.
TIRED Doesn't connect with iPhone calendar. Accumulation of gold doesn't win you a personal assistant.
