FIND YOUR BLUETOOTH DEVICES Search for compatible AirPods, wireless earbuds, headphones, Apple Pencil, speakers, smartwatches, and fitness trackers. Supported iPhone and iPad devices may also appear when they broadcast a detectable Bluetooth Low Energy signal. LIVE SIGNAL TRACKING Select a detected device and watch its signal strength change as you move. Walk slowly, compare readings, and focus your search on areas with a stronger signal.

HOW TO FIND A DEVICE 1. Turn on Bluetooth and allow Bluetooth access. 2. Open the app and scan for nearby devices. 3. Select the accessory you recognize. 4.

DESIGNED FOR EVERYDAY SEARCHES • Look for misplaced wireless earbuds at home. • Search for supported headphones near your desk. • Locate a compatible Apple Pencil around your workspace. • Find a nearby Bluetooth speaker or fitness tracker. • Check which compatible BLE accessories are within range. BEFORE YOU START Your accessory must be powered on, within Bluetooth range, and broadcasting a detectable BLE signal. Compatibility depends on the device model and its current state.
