Bluetooth access is how the app detects nearby devices, and iOS requires Location permission for Bluetooth scanning. Your location is used only to place signal readings on your own heatmaps. Nothing is uploaded anywhere.
Distances are estimated from signal strength (RSSI), which varies with walls, interference and how each device transmits. Treat them as a guide for getting warmer or colder, and use the AR Finder plus the sonar ping to home in precisely.
It watches for unknown Bluetooth Low Energy devices, such as item trackers, that appear to be moving with you over time. If one is flagged, check your belongings, car and bags. Green means no follower was found.
Continuous Bluetooth scanning does use extra power, like any scanner app. Stopping the scan when you are done keeps usage minimal. The app never scans in the background without telling you.
Yes. Everything is processed on your iPhone. There is no account, no analytics and no tracking. Local-only mode is the default, and you can wipe all app data from Settings at any time. Exports only happen when you tap export.
Make sure Bluetooth is on, the app has Bluetooth and Location permission in iOS Settings, and the other device is powered and advertising. Some devices only broadcast intermittently, so give it 30 seconds. A restart of the scan also helps.
iOS reports 0 for Wi-Fi signal strength to apps, so SignalRadar estimates dBm from your router's response time instead. It is accurate enough to compare spots and find dead zones, but it is not a lab-grade measurement.
No. iOS does not tell apps which tower you are connected to. Tower locations come from the OpenCelliD database, and the coverage map is built from your own samples as you move around.
An AirTag near its owner's iPhone stays invisible on iOS, so the app cannot see it either. Tracker Scan looks for unknown devices that appear to be moving with you across different places, which is the pattern that matters for your safety.
