Find headphones, AirPods, Fitbit, smartwatch or ANY gadget that is broadcasting in Bluetooth 4.0+. These include the following:
◆ Apple Devices: iPhone, iPad, AirPods, Watch, Pencil, Macbook
◆ Headphones, health bands, smartwatches, phones, trackers, home cameras and other gadgets from any platform or company like:
Android Wear, Beats, Bose, Fitbit, Garmin, Google, GoPro, Huawei, Jabra, Jawbone, JBL, Kindle, Kobo, LG, Microsoft, Misfit, Motorola, Polar, Samsung, Sony, Tizen, TomTom, Xiaomi, and many more other brands

INSTRUCTIONS:
1. Open the app and see the list of in-range actively broadcasting devices. If you cannot find your gadget it might either be configured to not broadcast, already paired, low battery, blocked by case, or in sleep mode. Smartwatches or bands if moved or rattled tend to wake up and begin broadcasting.
2. Tap the device you're interested in to start scanning. You can even see the battery info if available.
3. Move around slowly adjusting your direction based on the signal strength until you find your device.

It's that simple. Enjoy!
