When you attach Tile ($25) to something like, say.. your keys or wallet, you are virtually tethering that item to your phone.. So when you lose your stuff, you use an app on your phone to find it. It has a 100 foot range so if your stuff happens to be within 100 feet, you are loving it. But what if it’s not within 100 feet? Well that’s where its app really comes in handy. If your Tile is lost, tap the Mark as Lost button to report your lost Tile. Once your Tile has been found by either you or a Tile community member, you will be notified of the item’s location. Though it isn’t GPS enabled for real-time location information, the app does automatically record the last place your phone saw it. Because if you have to retrace your steps, it’s good to know where to start walking. The app can have up to 8 Tiles tethered to it so you can tether pretty much everything you need to keep tabs on.
