My wife is the queen of lists. She uses an iPHone 4s and can, a swipe and a couple of taps, pull up whatever information she needs to plan her next action. For example, she uses SplashShopper to track all our shopping lists. If we pop into Home Depot to pick up a gallon of paint, she checks to see what other hardware items we might need, saving a second trip. She has lists of gift ideas, quotes for greeting cards, honey-do’s and much more.
