Search for keys and other items easier with Sharper Tracker today. Sharper Tracker is a FREE tracking app available for iOS and other smartphones. Sharper Tracker uses your phone’s Bluetooth to help locate your Sharper Image Bluetooth® Tracker (sold separately) when the fob is attached to key rings, pet collars or anything else. There’s a notification searching system, last known location mapper, reverse search functionality and a bonus wireless selfie button for use with your phone’s camera. Plus, the tracking fob is a compact square that’s small enough it won’t get in the way with daily use on any keychain or pet collar. Avoid the hassle and anxiety of searching for lost keys and other important things from now on. Simply open the Sharper Tracker app and pair it to your Sharper Image Bluetooth® Tracker square. Once connected, Sharper Tracker lets you easily find the Sharper Image Bluetooth® Tracker fob. Open the app and select the connected Sharper Image Bluetooth® Tracker square to cause it to beep loudly. Follow the beep to find your key ring or pet anywhere. It’s like a beeping radar on your smartphone – pets and keys will never be lost again! The convenient mapper tracks the last location when the fob and app were together so you can find lost keys and pets easier. If the device and square are out of range of each other, just try going back to the Last Location noted on the map, try the finder function on your device again and listen for the beeps. Sharper Tracker can also work in reverse if you have the fob but can’t find the connected device. Use the button on the fob to cause your smartphone to start ringing for searching that’s quicker and more convenient – there are also a few more tone options beyond beeps. You’ll discover your smartphone’s location in no time. No more frustration or misplaced smartphone anxiety! If you had attached the tracking device to your pet’s collar, be sure to give them snuggles for helping you find your phone. As a bonus, Sharper Tracker can also work as a wireless camera button. Set up your phone for the perfect shot and use the button to snap the best selfies yet – all without racing or waiting for annoying timers. Smart devices just got smarter. The search for lost keys is a thing of the past. Welcome to Tomorrow’s Tomorrow™.
