Whether you're checking a hotel room, a short-term rental, an office, a car, or your own home, Hidden Device Radar gives you a fast, private way to spot devices that may be recording or tracking you. WHAT IT DETECTS • Bluetooth devices — trackers (AirTag, Tile, SmartTag, Chipolo), cameras, speakers, wearables, and other IoT gadgets • Wi-Fi / local network devices — IP cameras, baby monitors, NVRs, doorbells, and smart-home hardware • Unknown trackers that may be traveling with you • NFC tags — tap to identify a chip hidden in an object (on supported iPhones) KEY FEATURES • Real-time threat scoring — every device is flagged as Info, Suspicious, Elevated, or Critical • Signal Strength Finder — a "warmer / colder" proximity graph that helps you physically locate a device (Pro) • Scan modes for a quick sweep, a single room, or a whole floor • Detailed device fingerprints and manufacturer identification • Detection history so you can tell what's new versus what's always there • 100% on-device — your scans never leave your iPhone. No account, no tracking, no ads. 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.
