About this app

Your phone already has the sensors. SentryRF puts them to work.

SentryRF is the most advanced behavioural AI counter-surveillance app for Android. It turns your phone into a professional-grade Wifi and Bluetooth scanner that detects hidden trackers, spy cameras, drones, rogue WiFi networks, fake cell towers, and other surveillance threats — using on-device AI that learns your personal environment and gets smarter over time.

🔍 WHAT IT FINDS
━━━━━━━━━━━━━━━━━━
• Hidden Trackers — AirTags, Tile, SmartTags, Chipolo, Google tags, iBeacons, and unknown Bluetooth trackers. Identifies cloned and spoofed devices that fake their identity.

• Spy Cameras — WiFi cameras on hidden networks, infrared night-vision cameras (AI-powered IR flicker detection), and hidden electronics detected through physical sweep sensors.

• Surveillance Devices — Recording-capable smart glasses, surveillance drones with telemetry decoding, license plate readers, and acoustic monitoring equipment.

• Network Threats — Rogue WiFi networks impersonating real ones, network manipulation attempts, and fake cell towers intercepting your communications.

• Behavioral Threats — Devices following you across locations, trackers planted on your car or belongings, coordinated team surveillance, and repeat visitors at your location.

🛡️ HOW IT PROTECTS YOU
━━━━━━━━━━━━━━━━━━━━━━━━
On-Device AI — Multiple AI models work together to separate real threats from harmless devices. The AI learns from your feedback — whitelist your own devices and it gets smarter about what's normal in your life.

Sound Locator — Found a suspicious device? The AI-guided sound locator beeps faster as you get closer, helping you physically find hidden trackers in bags, vehicles, or rooms.

Physical Sweep — Your phone's magnetometer detects hidden electronics behind walls (hidden cameras, microphones, RF devices, etc..).
The microphone picks up ultrasonic emissions from camera circuits. The light sensor, enhanced by AI frequency analysis, detects invisible infrared illumination from night-vision cameras.

Network Monitor — Passively watches your WiFi connection for signs of interception, manipulation, or fake network attacks. No VPN required.

Evidence Reports — Generate tamper-proof PDF reports with cryptographic integrity verification for law enforcement or court proceedings. Every report comes with a verification hash.

⏱️ ALWAYS WATCHING

Ratings and reviews

Impressed, there is a problem if you live in the neighborhood, I gotten spammed or spoofed and had 70+ devices at critical . A response would be appreciated, Sentry, YOUR APP IS AWESOME, but it takes a minute to understand! When it says it doesn't mean someone is always tracking you , EVEN AT A CRITICAL LEVEL, pay attention to that, especially if your in the apartment. I will be a paying customer soon, BUT I CANT AFFORD SOME OF THE SOLDIERS YOUR PUTTING OUT, BUT AM IMPRESSED ON MANY LEVELS! 😇

Very intriguing app. It goes above and beyond. Helpful tips every step of the way for all the different nuances, unlike most security related apps. Endlessly dynamic and self-correcting, plus enthusiastic responsive replies to people looks like this has lots of endless potential. I wonder if it could be expanded to also use monitor mode capable devices or even SDR, or laptop versions in the future. Just brainstorming, because it's an inspiring app!

I'm genuinely impressed by what I'm seeing, leveraging multiple sensors to parse out a device, it's location, and a timeline of when it was first detected. The onboard data processing to assist in providing a whitelist is a great feature add and was a privacy feature I think can be worth its sub pricing that actually makes a smartphone 'smart'. I'm currently trying to protect my Tesla from vandalism and thought it's time to get a bit smarter about this.
