Someone could be tracking you right now. SentryRF turns your Android phone into a professional counter-surveillance scanner. Sophisticated detection engines catch hidden trackers, rogue WiFi, fake cell towers, and spy devices. Follower detection spots any device shadowing you across locations. Physical sweep finds hidden cameras using EMF, ultrasonic, and infrared sensors. Sound Locator guides you straight to the device. Everything runs locally-no cloud, no accounts, no data leaves your phone
Hello Product Hunt!
I built SentryRF because I felt helpless. Friends of mine were dealing with creepy situations — someone watching them, strange devices showing up near their car, not knowing if their hotel room was safe. I wanted to hand them something that could actually help, but nothing like that existed.
Then I watched a video about how security pros sweep rooms for hidden devices using expensive equipment. And I thought — wait, my phone already has all these sensors. Why can't it do this?
So I started building. What started as a simple "find a hidden AirTag" app kept growing because I kept asking: what else can we catch? That one question turned into:
Can we tell if a device is following you? Yes — the app now tracks if the same device shows up wherever you go.
Can we spot fake WiFi networks trying to steal your info? Yes.
Can we detect fake cell towers listening to your calls? Yes.
Can we find hidden cameras in an Airbnb? Yes — using your phone's built-in sensors to detect electromagnetic fields, ultrasonic sounds, and infrared light.
Can we check if someone stuck a tracker on your car? Yes — there's a dedicated vehicle sweep mode.
Today SentryRF runs 14 detection engines and recognizes over 4,500 device types. Everything happens on your phone. No cloud. No accounts. Nothing ever leaves your device.
The people who need this most — anyone who's ever felt watched, followed, or unsafe — shouldn't need to hire a professional or spend thousands on gear. Your phone can do it.
