Tile. This just makes a lot of sense. How many of us are constantly losing items around the house? Or even anywhere outside of the house? Well this app and device combo will potentially solve all of those problems. The Tile app uses these small tracking devices to help you keep up with your belongings. I think the idea is brilliant. The only drawback I see currently is that you have to send in and recycle each one after a full year of service. Seems a bit inconvenient, but other than that it's a great product.
