Ble Device Finder (Mac App)
This app can help you find your lost Smart Phone, Tablet, Smart Watch, Headphones, or other Bluetooth devices.
Bluetooth Radar can detect all nearby devices. Find and select your lost device on the list, then move around slowly and keep watching the signal strength, estimated distance, and hints on the screen. When it reads “Your Device Is Here!”, please look around. You should find your device nearby.
