TrackerSonar finds hidden tracking devices around you. Scan for Bluetooth trackers and tags in seconds and get a clear answer: "No trackers found" or "1 possible tracker nearby". Check your bag, your car or a hotel room, see which devices keep showing up near you and walk straight to a hidden tag with a hot/cold signal meter. SCAN FOR HIDDEN TRACKERS Tap "Scan for Trackers" and watch the live radar fill up. Possible trackers are listed first, followed by other nearby Bluetooth devices such as AirPods and Apple devices. Simple filter chips keep the list tidy. SEE WHAT NEEDS YOUR ATTENTION SUSPICIOUS marks tags that can be used to track people. TRACKED marks devices that were seen at several places. Mark your own tags as known and they no longer show up as suspicious. FIND THE DEVICE WITH LIVE LOCATE Live Locate follows one device's Bluetooth signal in real time. The gauge and haptic ticks grow stronger as you get closer, so you can find a tag tucked into a bag, a coat or a car. On supported tags, play a sound to hear where it is. The same finder helps you locate your own earbuds or headphones nearby. IS IT FOLLOWING ME? Every scan remembers where devices were seen. The sightings map and timeline show when and where a device turned up near you, so you can tell whether something really moves with you. ALERTS IN THE BACKGROUND Turn on continuous scan and get a notification when a tracker shows up near you, even while TrackerSonar runs in the background. A widget and a Live Activity show your protection status at a glance.
