RF Detector App: Detect Hidden Cameras, Spy Bugs & Trackers.
ReFi is your essential RF signal detector app engineered to sweep spaces, pinpoint rogue wireless transmissions, and detect hidden cameras with zero cloud telemetry. Turn your smartphone’s native 3-axis magnetometer and wireless sensors into a surgical spectrum analyzer.
The Only RF Detector App Built to Protect You, Never Track You
Unlike ordinary tools, this RF signal detector app runs entirely in memory without third-party ad networks or remote telemetry. True air-gapped detection.
100% Offline Processing
All magnetometer oscillations, RF frequency spectrum sweeps, and Bluetooth beacon triangulations are computed directly inside device silicon. Zero packets transmitted.
Zero Account Required
No signup forms, no email collection, and no device fingerprinting. Launch the application and begin sweeping within 2 seconds of entering any unverified space.
No Data Sharing or Sales
We operate on a transparent utility model. Your sweep logs stay isolated on your phone. We never sell, auction, or syndicate location telemetry to data brokers.
Six Precision RF Signal Detector App Inspection Layers
Each layer reads a different phone sensor: the magnetometer finds EMF from hidden electronics, Wi-Fi scanning finds streaming cameras on the network, and Bluetooth LE monitoring finds AirTags and other trackers following you.
Smart RF & EMF Detector
Locate electromagnetic emissions generated by concealed circuit boards, micro-lenses, covert audio bugs, and hidden live wire transmissions behind drywall.
Precision Network Scanner
Deep-scan connected LAN and Wi-Fi subnets to pinpoint suspicious streaming RTSP camera channels, unauthorized P2P relays, and obscure hidden IoT nodes.
Real-Time Signal Radar
Dynamic high-refresh spectrograms and frequency curves spike instantaneously as the antenna gets closer to covert high-frequency transmitters.
Tracker & AirTag Guard
Identifies foreign Bluetooth Low Energy trackers (Apple AirTags, Samsung SmartTags, Tile tags) traveling with you and separated from their verified owners.
Tactile & Silent Sweeps
Conduct discreet inspections in occupied quarters with calibrated micro-haptic engine pulses or optional sub-audible Geiger audio ticks.
Local Cryptographic Export
Export scan snapshots, MAC fingerprints, peak milligauss telemetry, and UTC timestamps with one tap to local secure storage or legal files.
Built For Anyone Who Values Absolute Discretion
Frequent Travelers & Guests
Execute a 90-second perimeter sweep of holiday rentals, boutique hotel bedrooms, bathroom ceiling fixtures, smoke detectors, digital clock radios, and two-way vanity mirrors before unpacking.
- Smoke detector IR diode check
- Bedside electronics EMF isolation
Corporate Executives & Legal
Sanitize confidential boardroom environments, offsite advisory hubs, and private interview suites against rogue GSM taps, wireless omni-mics, and illicit Wi-Fi eavesdroppers before material disclosures.
- Subnet Wi-Fi stream enumeration
- Audio bug transducer field detect
Privacy Advocates & Everyday Users
Proactively counter unwarranted stalking, unknown Bluetooth tags placed in backpacks or luggage, and magnetic vehicle undercarriage GPS tracking modules with precision proximity feedback.
- Vehicle wheel-well magnet locator
- Unpaired BLE beacon notification
Execute a 3-Step Guided Sweep
No specialized technical expertise required. The intelligent algorithm normalizes baseline environment noise automatically.
Launch & Calibrate
Hold your smartphone in the center of the room. Tap calibrate to establish baseline magnetic ambient levels in under 2 seconds.
Perimeter Sweep
Move slowly within 2 to 6 inches of suspected hardware—power outlets, air conditioning grills, alarm clocks, and mirror frames.
Zero In & Neutralize
Watch live microtesla waveform spikes and feel haptic pulse frequency intensify as you pinpoint the exact transmitter position.
Tested in the Field by Thousands
“Now as a hobbyist in RF electronics I understand the phrases and concepts... well put, well done. Highly intuitive interface and honest sensor readout.”
“The magnet sweep and instant localized microtesla readings gave me total peace of mind on my Airbnb trip. Found a suspect power adapter behind the TV in seconds.”
“Zero account signups. That alone makes ReFi superior to everything else in the App Store. Pure utility, responsive haptics, and zero tracking.”
Frequently Asked Questions
Have questions about how consumer smartphones detect electromagnetic surveillance hardware? We believe in complete technical candor.
ReFi utilizes your smartphone’s integrated magnetometer, Wi-Fi hardware, and Bluetooth LE radio. While remarkably effective as a first line of consumer defense for live electronic components and transmitters, standard commercial smartphones cannot detect dormant or military-grade frequency-hopping equipment.
How does a smartphone detect hidden cameras?
Does ReFi require an active internet connection?
Can it locate unknown AirTags, SmartTags, and GPS trackers?
