Wireless Key Finder with GPS remote control and Bluetooth 5.0 technology allows you to easily search for and locate lost items. This item locator works with a dedicated app compatible with iOS and Android devices. The app can be downloaded from the App Store or Google Play. (Note: Requires iOS 8.0 or later / Android 4.3 or later) Two-way Search Functionality Use the app to trigger a sound on the tracker to help locate your misplaced item. To find your phone, simply press the button on the tracker twice in quick succession, and your phone will ring—even if it's on silent mode. Smart Separation Alert If the connection between the tracker and your phone is lost beyond the effective range, both the app and the device will send a notification. The app records the last known location where the tracker went out of range, helping you narrow down your search area. Ideal for individuals who frequently misplace items. Effective Range The wireless signal range between the tracker and smartphone is approximately 15 to 30 meters in open areas. Actual distance may vary depending on obstacles such as walls or interference. Compact and Portable Design The finder is small and lightweight, making it easy to attach to keys, wallets, backpacks, luggage, and more. Convenient for everyday use. This package includes four trackers, providing versatile tracking solutions for multiple items.
