Grandma. As much as you love the old girl, she does have a tendency to drift off anytime you’re within 75 yards of a Pottery Barn. And then it’s all “But why did you leave her stranded at the mall!?” when you see your parents. You don’t need that kinda hassle. You need these new StickNFind Bluetooth Stickers ($35). Just put one on anything you don’t wanna lose – remote control, keys, aging relative – and let your phone track it down for you via Bluetooth signal. The app lets you to keep track of up to 20 objects at a time, with a range of about 100 feet. Stay close, granny.
