HIDDEN DEVICE RADAR PRO Unlock everything with a one-time purchase: • Signal Strength Finder • NFC Tap-to-Identify • Full threat analysis and guidance • Unlimited detection history • AI Trend Insight HONEST ABOUT LIMITATIONS Hidden Device Radar detects devices that broadcast Bluetooth, Wi-Fi, or NFC signals. Bluetooth, Wi-Fi, and NFC advertisements are unauthenticated, so results are strong investigative leads — not legal proof of a device's identity or intent. The app cannot detect devices that are powered off, purely analog/wired, or that broadcast no signal. PRIVACY FIRST Everything runs locally on your device. We don't collect, upload, or sell your data. There are no accounts and no ads. Use Hidden Device Radar to check your own spaces and protect your own privacy. Always follow the laws in your area.
