Searching was yesterday, finding is today: The Key Finder helps keep track of devices and items, and in combination with the "Find My Device" app, allows you to locate them anytime. It's all about quantity: Add the Key Finder to the "Find My Device" app and locate items using millions of Android devices from the Google network. Start tracking: Use the loud sound signal (up to 78 dB) to locate the missing item. Better safe than sorry: Unauthorized tracking of location data and history is prevented by advanced encryption. Losing is a thing of the past: The Key Finder can be attached to your backpack, keys, and all important items, and even to a dog that likes to wander off. With a hole and an additional loop, the Key Finder can be directly attached to a keyring or the loops of a backpack or bag. Water-resistant with IPX5.
