Every detection method.
One app. Works offline.
NoSpy combines four independent scanning techniques so no camera type slips through — including offline SD-card cameras that every other app misses.

Four ways to catch what the naked eye can’t.
Each method targets a different camera type. Used together, they cover the full realistic threat range — from actively streaming cameras to completely powered-off devices.
AI camera scan
Computer-vision analysis of your camera feed highlights reflective surfaces and pinhole lenses characteristic of spy cameras hidden in everyday objects — hooks, chargers, frames.
Infrared lens detection
Most night-vision cameras emit infrared light invisible to the human eye. NoSpy’s IR mode uses your front camera — which lacks the IR-cut filter found in rear lenses — to reveal these sources as bright points of light.
Magnetic field sweep
Your phone’s magnetometer detects anomalies caused by the small motors, transformers, and electronics inside hidden recording devices embedded in walls, outlets, and furniture.
Wi-Fi network audit
Lists every device connected to the local network — including cameras streaming live footage under generic or disguised names. Flags devices that match known spy camera MAC address patterns.
Bluetooth tracker scan
Finds AirTags and BLE trackers hidden in bags, under vehicles, and inside luggage — with signal strength to pinpoint location.
100% offline operation
Every detection mode runs entirely on your device. No image is uploaded. No data leaves your phone — not on the free plan, not on premium. Scan freely in airplane mode.
⚠ The camera type every app misses — and how NoSpy handles it
A motion-activated camera recording locally to an SD card emits no Wi-Fi signal, no Bluetooth, and no infrared light. It is invisible to RF detectors and IR sweeps alike. NoSpy’s AI lens scan and physical inspection guide detect it via the optical glass reflection — a physical property of the lens that persists whether the device is on, off, or in standby.

🚫 No account required
Download and scan immediately. No registration, no email, no profile. The free plan never asks for a credit card.
📵 No image uploads
Camera feed analysis runs locally using on-device ML. Your images are never transmitted, stored on a server, or accessible to us.
🔍 Only asks for permissions it needs
Camera (for lens detection), motion (for magnetometer), and local network (for Wi-Fi audit). Nothing else. Permission use is explained inside the app.
