I’ve been testing Camera Detector in real-world scenarios—like checking into an Airbnb or working from a coworking space—and it’s surprisingly handy. The magnetic field scanner picks up on electronics you might miss, and the infrared detection helps spot pinhole lenses. It’s not foolproof—sometimes it flags harmless electronics like routers—but it gives solid peace of mind. The interface is clean, and I like how it logs scans so you can review later. Battery drain is reasonable, though extended scanning does heat up the phone a bit. For under $5, it’s a no-brainer if you value discretion. Just remember: no app replaces a physical sweep, but this gets you 90% of the way there.
