With most physical paper and printouts having gone by the wayside, sometimes I just miss the feeling of stapling forms together and filing mountains of paperwork. If you can relate, SimStapler (free) is the game for you. The app shows a pixelated red stapler on an older Apple desktop background, and all you have to do is press the stapler. Each press earns you a point, and you’re rewarded with a satisfying stapler “click” sound. How many virtual paper stacks can you get through?
