The Missing Half of Device Tracking
Apple Find My is an extraordinary global crowdsourced network for tracking MacBooks, iPads, and AirTags left at airports or coffee shops. However, Find My is fundamentally limited: it only tracks hardware registered inside Apple's walled garden. If you misplace a $300 pair of Sony WH-1000XM5 headphones, a Kindle Paperwhite, a Fitbit Charge, or a smart TV remote, Apple Find My is completely useless.
How Sweep Bridges the Gap with Universal BLE Scanning
Every wireless gadget broadcast periodic 2.4GHz Bluetooth Low Energy advertising packets. Sweep listens to these raw radio waves directly through your iPhone's Bluetooth transceiver. As you walk through your home or office, Sweep plots a real-time signal strength meter (RSSI in dBm) with haptic feedback, turning the search into an intuitive game of "hot and cold."
Locating Lost Single AirPods Behind Cushions
When you drop a single AirPod inside a vehicle or under a couch, Apple Find My often displays only the location of the charging case. Sweep isolates the distinct BLE MAC address broadcast by the loose earbud, allowing you to narrow down the search to within a 30-centimeter radius.
