This is a simple accounting app I made for my wife. We are trying to keep some variety in the meal plans, so we're not giving the kids the same thing over and over. You get a color-coded list of meals that you've served - red if you've dished it out recently, blue if it's been a while, green if you're in the goldilocks zone of neither too soon nor too long. The idea for the name was it's like playing Whac-A-Mole (TM), in that you are constantly trying to keep all the meals in that green zone.
