Works with Apple Find My: Simply use the pre-installed Find My app and add the Air Tracker tag to the Items tab. You can then find it anywhere in the world using Apple's network of millions of devices. (Note: not available for Android) Find Nearby: With a Bluetooth range of up to 200 feet/60 meters, when the Item Finder is in range, you can use the Find My app to locate your lost item, or simply ask Siri for help. The built-in speaker (loud, 90-100 dB) emits a beep to help you locate your item. Tracking from a Distance: The Key Finder seamlessly connects to the Find My network on your iOS device, allowing you to track your item from a distance. Even if you're out of Bluetooth range, you can use the Find My app on iOS to see the real-time location of the Smart Tag on a map, and navigation will guide you closer to the tag's location. Lost Alert & Lost Mode: If you lose an item with our tracker tag and the Bluetooth connection to your iOS device is lost, the Find My app will immediately send you a notification that your item is missing (at no additional charge). If you preset lost mode and retain contact information, the Bluetooth tracker will allow nearby Apple devices to access your contact information and provide you with the location of the locator remotely. Privacy Protection: Devices transmitting location data always remain anonymous, and this information is encrypted at every step of the search process. The key finder tracker itself does not store location data or history; only you can access the location of your items, ensuring maximum privacy protection. Replaceable Battery and IP67 Waterproof: The key locator is IP67 waterproof, ensuring that the tracker can withstand everyday challenges. It is powered by a CR2032 button battery with a service life of up to 1 year. When the battery is low, the Bluetooth locator will notify you to replace the battery, and you can purchase this battery to replace it yourself. The unique cover design also prevents children from opening the device easily.
