SentryRF is your digital sixth sense for invisible threats. It turns your Android phone into a powerful scanner that finds hidden trackers, spy cameras, drones, fake WiFi, and more. The AI identifies devices by name — iPhone, AirPods, Galaxy, smartwatch — and learns what's normal around you. When something suspicious appears, you'll know. Everything stays on your phone.
These are the situations SentryRF is built for — and how SentryRF responds to each one.
A small tracker slipped into a pocket, a purse lining, or tucked under a car seat. It silently reports your location through Apple's Find My network — no pairing required.
A magnetic black box attached under the wheel well or inside the bumper. Invisible from outside the car — broadcasting your every trip.
A pinhole camera inside a smoke detector, alarm clock, or wall fixture. Connected to the property's WiFi or storing footage locally on a hidden network.
A drone circling overhead — could be a neighbor, a PI, or someone casing your home. Without Remote ID decoding, you'd never know who's flying it.
Someone at a meeting, a bar, or a private event wearing Ray-Ban Meta or Snap Spectacles — recording video without anyone's knowledge or consent.
ALPR cameras mounted on poles by private surveillance companies — logging every vehicle that passes, building a searchable database of your movements.
A Tile, SmartTag, or Chipolo placed in a backpack, lunchbox, or jacket — tracking a child's daily routine between home and school without anyone noticing.
Suspected surveillance in an apartment, office, or hotel room — wired cameras, audio bugs, or passive recording devices that don't show up on a Bluetooth scan.
A rogue access point broadcasting the same network name as the real one — anyone who connects has their traffic intercepted, passwords captured, sessions hijacked.
No tracker needed — a person following you on foot or by car, using their own phone's Bluetooth as an unintentional beacon. Most tracker apps can't detect this.

Once SentryRF identifies a suspicious device, the AI-guided Sound Locator helps you find its exact physical location. It uses adaptive per-device calibration — the AI tunes signal parameters for each specific tracker type, adjusting for known transmit power, path loss, and even obstruction detection when a tracker is hidden inside a bag or car panel.
SentryRF doesn't just list nearby devices. 11 on-device AI models and Google's Gemini Nano watch for patterns that reveal when a device is tracking you — and a growing knowledge base learns from your feedback to get smarter with every scan.
SentryRF scans Bluetooth and WiFi at the same time. It knows what a device is — iPhone, AirPods, smart speaker, hidden camera — by checking it against a huge database of known devices.
A random AirTag at the coffee shop is harmless. The same AirTag at the coffee shop, your office, and your home is a threat. SentryRF runs 11 AI models and Google's Gemini Nano — all on your phone — to watch for patterns across time and location. It learns what's normal and alerts you when something isn't. Tap any device for a plain-English explanation.
SentryRF doesn't just see devices — it figures out exactly what they are, including details that other apps miss entirely.
Hackers create fake WiFi networks that look like the real thing — your hotel, your coffee shop, your airport. SentryRF catches these imposters and monitors your connection for signs of interception or manipulation.
Some surveillance devices don't broadcast wirelessly — wired cameras, audio bugs, passive GPS loggers. Your phone's built-in sensors can still detect them through their electromagnetic and optical emissions.
SentryRF runs in the background and notifies you the moment a confirmed threat is detected. Every encounter is logged with signal data, location, and timestamps so you can see the full picture over days, weeks, and months.
From Bluetooth tracker detection to room sweeps, SentryRF covers every angle of covert surveillance.
Continuous Bluetooth and WiFi monitoring with on-device AI threat classification detects AirTags, Tiles, SmartTags, and unknown trackers — even when your phone is in your pocket. The AI learns from your actions to reduce false alarms.
Detects devices following you across locations or staying attached to your vehicle, bag, or belongings over time. Catches both known trackers and unmarked devices.
Identifies devices that keep returning to your location across separate visits. Nighttime appearances are flagged with extra urgency — someone casing your home won't go unnoticed.
Catches fake WiFi networks pretending to be your hotel, café, or airport. Alerts you if your connection suddenly becomes less secure, or if a suspicious login page appears.
Uncalibrated magnetometer with Geiger-counter haptics that pulse faster as you approach hidden electronics. Acoustic spectrum analyzer detects ultrasonic emissions. Light sensor catches IR illumination. All with real-time waveform visualization.
Detects invisible infrared light from hidden night-vision cameras. Finds the telltale flicker that spy cameras produce — invisible to your eyes, but SentryRF can see it.
Smart proximity tracking that gets more accurate for each type of device. Walk toward the hidden tracker and the beeps guide you right to it.
Detects Flipper Zero and ESP32 devices masquerading as AirTags or SmartTags. 5-signal analysis checks hardware chip, TX power, key rotation, advertising interval, and BLE spam patterns.
Passively monitors your WiFi for evil twin attacks, DNS hijacking, gateway swaps, and deauthentication attacks. Alerts you before your data is intercepted — no VPN required.
Scans every device on your WiFi network. Finds hidden cameras connected to WiFi, checks if your router is secure, spots devices with default passwords, and catches anything that shouldn't be there.
Dedicated scan profile optimized for detecting trackers planted on your car. Walk around your vehicle once and SentryRF flags anything that doesn't belong.
Monitors cell tower changes and signal anomalies that may indicate fake cell towers intercepting your calls and messages.
See every detected device on a map. Set safe zones around your home or office — SentryRF learns what's normal and only alerts you to new, unfamiliar threats.
Catches organized surveillance — multiple people taking turns following you, parallel teams, and scheduled surveillance patterns that no single tracker would reveal.
Generate tamper-evident PDF reports with sweep heat maps, timestamps, and signal data. Each report includes cryptographic integrity verification that proves the document hasn't been modified.
Watch a suspicious device's movement history play back on the map — see exactly where it's been, when it appeared, and whether it's been following you.
Walk through any room and build a live heat map of EMF and BLE anomalies. AI cluster analysis pinpoints hidden electronics vs structural wiring with numbered crosshairs — exportable in evidence reports.
Tap any detected device for a plain-English AI explanation powered by Google's Gemini Nano — running entirely on your phone. Confirm or correct the AI's assessment and it learns from your feedback.
AI tells the difference between hidden electronics and normal wiring in your walls. Shows you exactly where suspicious signals are coming from during a room sweep.
Task switcher blur hides your scan data in Recent Apps. Optional screenshot protection blocks screen recording. Live data safety audit verifies zero analytics SDKs and all-local storage.
All data stays on your device. No cloud, no accounts, no tracking. Your scan results never leave your phone. Delete everything with one tap, anytime.
Download SentryRF from Google Play and grant Bluetooth and location permissions. No account required — you're scanning in under a minute.
Tap Scan to sweep for nearby trackers and wireless devices. Walk around your car, your room, or your belongings at a normal pace.
Review flagged devices, check why they were flagged, use Sound Locator to find hidden trackers, or run a Physical Sweep of the room.
