App removes wandering people from photos

Remove works by initially taking a burst of shots in succession. By comparing those shots with one another, it is then able to identify which objects are stationary (the scenery, and/or your posing subject) and which ones are moving (those dang people). It then highlights the moving objects on a preview screen, and allows you to select which ones to remove. The end product is a composite photo, with the offending humans taken out.
