Camera, or paranoia? Check it in 5 minutes.

It sees you.
You don’t see it.
A lens reflection only shows from the right angle; take one step and it’s gone. Infrared light is invisible to the eye. Hidden Eye makes them visible on your phone: it marks lenses with a red ring, points out what faces the bed or shower, and tells you the next step if you find something.

Six ways to catch a hidden camera
Flash, darkness, signals, magnetism, mirrors and AI. A camera can hide from one of them, not from all six.
Lens Finder Free
The flash blinks; any tiny spot that blinks back is a lens, and the app circles it.
Lights-Off Test Free
Some cameras glow in the dark. Your phone’s camera catches what your eyes miss.
Mirror Test Free
A fingertip test that tells a normal mirror from a two-way one.
Device Scan Pro
Wi‑Fi and Bluetooth devices around you; cameras and trackers get a red label.
AI Scan Pro
One photo; AI marks spots worth checking and what points at the bed or shower.
Electronics Finder Pro
Hold your phone close to an object; it senses electronics hidden inside.
The doubt goes. The report stays.
Mark each spot as you check it. You end up with a safety score and a report you can keep, share, or send straight to the host.
Delete it whenever you like. You stay in control.

Questions, answered
How does Hidden Eye find hidden cameras?
It uses your flash to catch lens reflections, your camera to spot infrared lights in the dark, your compass to sense electronics inside objects, Wi‑Fi and Bluetooth to find spy devices, and AI to point out anything aimed at the bed or shower.
What does the red circle mean?
It marks a spot that reflects light like a lens or glows like a camera light. Look at it up close, check it with the Electronics Finder, and if it’s a camera, follow the Found something? steps.
What are checked places?
Hotels, rentals and spas that scan their own rooms with Hidden Eye and publish every report on hiddeneye.ai. Each page shows the latest scans, how many rooms were scanned and how many guests scanned there.
Where do my photos go?
Hidden Eye doesn’t watch you. Lens Finder, Lights-Off Test, Mirror Test, Electronics Finder, Device Scan, Tracker Check and Night Watch run only on your phone. AI Scan photos are analysed on our server and kept with your result until you delete it. Listing screenshots are analysed and not stored. AI Scan Coach frames are sent only if you allow it and are deleted within 7 days.
How do I cancel my subscription?
In your App Store or Google Play subscription settings. Deleting the app doesn’t cancel it. You keep Pro until the end of the period you paid for.
