btSWARM vs BlueSpot Finder

The SWARM application is customized to locate proprietary beacons placed inside shipments sent to retailers.

Tap Scan. BlueSpot lists every nearby Bluetooth device — AirPods, headphones, speakers, watches, fitness trackers — and shows which one is closest. Pick the one you've lost, then watch the number climb from "Far" to "Getting warm" to "Very close" with every step you take. Haptic pulses and optional beeps confirm when you're on top of it. No accounts. No subscriptions. No ads. Nothing to set up. Open the app, tap Scan, and find your stuff in seconds. WHAT YOU CAN FIND • AirPods, AirPods Pro, AirPods Max • Beats, Sony, Bose, Jabra, and other wireless headphones • Bluetooth speakers (HomePod, JBL, Sonos, Bose Soundlink) • Fitness trackers (Fitbit, Whoop, Amazfit, Oura, Mi Band) • Apple Watch, Garmin, Galaxy Watch • Any Bluetooth LE device broadcasting a name HOW IT WORKS BlueSpot reads radio signal strength (RSSI) from nearby Bluetooth devices. Stronger signal = closer. A built-in filter smooths out the noise so you see a steady 0-to-100 proximity score instead of jumpy numbers, and haptic and audio alerts let you know when you've nailed it. This is proximity tracking, not GPS. BlueSpot tells you whether you're getting closer or farther — perfect for "I know it's in this room somewhere" moments. It is not a replacement for location-based tracking services. WHY PEOPLE LIKE IT • Instant scan — every nearby Bluetooth device, in seconds • Auto-categorized — AirPods, headphones, watches, speakers, and trackers grouped for you • Smooth proximity meter — real-time 0-to-100, no wild jumps • Haptic guidance — your phone pulses faster as you get closer • Audio cues — optional beeps that speed up near the target • Favorites — pin the devices you lose most so they're one tap away next time • Adjustable alert threshold — tune the "found it!" trigger • Full dark mode • Works offline — no internet required • No signup — open and go PRIVACY FIRST BlueSpot collects nothing.
