Sweep: Bluetooth Device Finder

Lost your earbuds, headphones or keys with a Bluetooth tag? Sweep is a Bluetooth finder that turns your phone into a live hot-cold radar and walks you straight to the device.

Find my device the easy way: open the locator, walk around and watch the signal grow warmer. The app also checks for unknown trackers around you and shows who is on your Wi-Fi.

✓ Live radar with distance and a "getting closer" trend
✓ Play a sound on supported gadgets and tags, see their battery level
✓ Locate lost earbuds and headphones, including ones paired in your phone settings
✓ Tracker detector: spot unknown AirTag, SmartTag, Tile and Find Hub tags that move with you
✓ Background alerts, even when the app is closed, with a 24-hour log
✓ Meet a friend: two phones, a 4-digit code and a hot-cold signal that leads you to each other
✓ Wi-Fi scanner (Pro): everything on your network, routers, cameras and printers
✓ Wi-Fi analyzer with channel load and a speed test
✓ Home screen widget, quick settings tile and app shortcuts

HOW IT WORKS
Every Bluetooth gadget sends a signal. Sweep reads its strength many times per second, smooths out the noise and turns it into a distance and a hot-cold scale. Walk in one direction: if the radar gets warmer, you are on the right track. Save an item once and it stays in your list.

TRACKER DETECTOR FOR ANDROID
Worried that someone slipped an AirTag into your bag or car? The app looks for tags separated from their owner that stay near you for a long time. You get a clear alert and can walk to the tag with the radar.

WHO IS ON MY WIFI
The network scanner lists everything connected, with its name, maker and open services, so a stranger stands out. The Wi-Fi analyzer shows nearby networks and the least busy channel.

MEET A FRIEND IN A CROWD
At a festival, airport or parking lot, both of you open the app, pick the friend's code and follow the signal. On phones with Ultra Wideband, precise mode adds a direction arrow.
