The hipKey Tracking Device and App combine to form a revolutionary product that will help you instantly locate a valuable object. You just attach the hipKey to your most precious belongings, which can be anything from your child or pet to your iPhone or iPad. In fact, it works both ways for the iPhone. You can find the hipKey using the iPhone app, or use the hipKey to find your iPhone. The basic concept is to trigger an alarm on the object you’re looking for, so that you can zero in on its location. Obviously, it only works when the hipKey and the iPhone on which the app is loaded are within range of each other. If they get separated and the distance grows to more than 164 feet, the alarm is automatically triggered.
