The TrackR is the size of a coin, and you can attach it to your keys or any other item that you frequently misplace. Then next time you lose that item, the TrackR will help you find it. To use the TrackR, you must have one of these mobile devices: iPhone 4s or later, iPad with Retina Display or later, or the Android 4.4 with Bluetooth 4.0. Once you receive the TrackR, download the TrackR app to one of the aforementioned mobile devices, and when you misplace the item that you put the TrackR on, the app causes the item with the TrackR to ring.
