Professional Bug Detection, Zero Learning Curve
Every scan is guided, visual and instant — here is exactly what SpyMic shows you while it works.
Four Detection Methods. One Sweep.
Hidden microphones give themselves away in different ways — a magnetic field, a Bluetooth beacon, a Wi-Fi connection, or heat. SpyMic checks all four so a bug that hides from one method gets caught by another.
EMF Sensor Scan
Your iPhone's magnetometer picks up the electromagnetic fields hidden mics and electronic bugs emit. Move your phone near suspect objects — SpyMic alerts you to unusual activity.
Bluetooth Device Finder
Scans for nearby Bluetooth transmitters with a focus on audio-related and suspicious hardware — wireless microphones, beacon trackers and eavesdropping tools.
Wi-Fi Network Scan
Reveals every device connected to the same network — IP cameras, microphones and IoT gadgets included — even when they're disguised or unnamed.
Thermal & IR Detection
Uses your camera to spot heat signatures and infrared light from hidden electronics — catching powered devices that other methods can miss.
🔔 Real-time alerts
Instant feedback with progress bars and visual heatmaps while you sweep — no expertise needed to read the results.
🏨 Built for travel
Purpose-made flows for hotel rooms, Airbnb rentals, meeting rooms, offices and vehicles.
🔒 Private by design
App Store privacy label: Data Not Collected. Scans never leave your device.

Straight answers to the most-searched questions about finding hidden microphones, listening devices and spy cameras.
Can my iPhone really detect hidden microphones?
Yes — within limits. Your iPhone's built-in magnetometer can pick up the electromagnetic fields electronics emit, its camera can reveal infrared light from night-vision devices, and Wi-Fi and Bluetooth radios can list every transmitting device nearby. SpyMic combines all four sensors into one guided sweep. No phone app can guarantee it will find every device, but a multi-method scan catches the most common consumer bugs. Learn more →
How do I find hidden microphones in my house?
Combine a physical inspection of common hiding spots (smoke detectors, chargers, lamps, vents, décor) with an electronic sweep. Use SpyMic's EMF scanner near suspicious objects, run its Bluetooth and Wi-Fi scans to reveal transmitting devices, and finish with a lights-off infrared camera check. Learn more →
What's the fastest way to detect listening devices in a room?
Run a three-part electronic sweep: scan the Wi-Fi network for unknown connected devices, scan for nearby Bluetooth transmitters, then walk the room with an EMF detector near likely hiding spots. SpyMic runs all three from one screen in about a minute. Learn more →
How do I check an Airbnb for hidden cameras and microphones?
On arrival, join the rental's Wi-Fi and scan the network for camera and microphone devices, check bedrooms and bathrooms with an infrared lens scan in the dark, and sweep smoke detectors, clocks and USB chargers with an EMF scan. SpyMic performs each of these checks step by step. Learn more →
How do I check a hotel room for hidden devices?
Focus on sightlines to the bed and bathroom: alarm clocks, TVs, smoke detectors, outlets and mirrors. Run a Bluetooth scan for unknown transmitters, an infrared scan with the lights off, and an EMF sweep of fixtures. SpyMic guides the whole hotel sweep in a few minutes. Learn more →
What do hidden listening devices look like?
Most consumer bugs are disguised as everyday objects: USB chargers and power banks, smoke detectors, pens, alarm clocks, air fresheners, light bulbs and picture frames. Tell-tale signs include pinholes, extra seams, unexplained LEDs, and objects that feel heavier than they should. Learn more →
How can I tell if my house is bugged?
Warning signs include others knowing private conversations, items moved or new objects appearing after visits, unusual interference on calls or speakers, unknown devices on your Wi-Fi, and unfamiliar Bluetooth signals in certain rooms. Confirm suspicions with a systematic electronic sweep. Learn more →
How do I see every device connected to my Wi-Fi?
Use a network scanner. SpyMic's Wi-Fi scan lists every device connected to the same network — including cameras, microphones and IoT gadgets that don't show up in your router app — so you can spot hardware that shouldn't be there. Learn more →
How do I find a tracker or bug hidden in my car?
Physically check the OBD port, under seats, bumpers and wheel wells, then scan: Bluetooth reveals nearby beacon trackers and wireless mics, and an EMF sweep along the dash, seats and trunk flags powered electronics. SpyMic runs both scans from your phone. Learn more →
What should I do after finding a listening device?
Don't touch, unplug or destroy it — that can alert whoever planted it and damage evidence. Photograph it in place, document the date and location, move sensitive conversations elsewhere, and contact local police. Learn more →
