Track Your Belongings with iOS Find My: Simply attach the key finder to your keys, luggage, backpack, pet, and more, then easily track and locate your items worldwide via the Find My app. Never lose your important belongings. Android devices are not supported. Find Nearby: With just a tap in the Find My app, the key tracker will emit a 100dB sound. This means you can hear and find it if it's covered or in the next room (Bluetooth range within 60m/200ft). Forgotten Item Reminder: Receive instant notifications on your phone if you leave your tracking transmitter behind (at no extra charge). Use the Find My app to see the smart tag's last known location on a map, so you'll never lose anything again. Replaceable Battery & IP67 Waterproof: The tracking transmitter comes with CR2032 batteries for uninterrupted use. Additionally, it easily withstands rain and splashes with its IP67-rated luggage tracker. Multiple Functions: The key finder has many useful features such as Worldwide Tracking without limitations, Lost Mode, Anti-stalking System, and more. A perfect gift for forgetful friends and pet owners. Share Your Belongings & Privacy Protection: Luggage tracking allows your friends and family to see your item's location (new feature for iOS 17). Meanwhile, the chip in this Bluetooth tracker is MFi certified, ensuring your location data is encrypted for everyone else, not even the manufacturer.
