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 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. 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
━━━━━━━━━━━━━━━━━━━
• 24/7 background scanning — stays active even when you close the app
• Instant alerts — sound, vibration, and notification when threats are detected
• Map tracking — see every detected device on a map with movement history
• Safe zones — set trusted areas around home and work to reduce false alarms
• Timeline — review months of detection history to spot long-term patterns
• Vehicle check — dedicated mode for scanning your car for planted trackers
• Cooperative multi-device tracker localization using up to three phones and WearOS devices.

🔒 100% PRIVATE
━━━━━━━━━━━━━━━━
Everything stays on your phone. Period.
• No cloud servers — all AI runs locally
• No user accounts — install and start scanning
• No data collection — your scans are yours alone

Ratings and reviews

cool idea but doesn't seem to work correctly and doesn't warn you that it can't distinguish between apple products. So "apple BT" detections flag the same giving it a critical threat level but actually is likely 50 totally unique unrelated devices. Would be an easy 5/5 if it fully delivered.

SentryRF stands out by turning Bluetooth, BLE, and Wi Fi scans into clear, useful insights instead of raw device lists. Scanning is fast and the interface is clean. It’s especially useful for tracking recurring devices over time and understanding your RF environment. There’s strong potential for smarter device grouping, behavior based tracking, and better signal interpretation using data Android already provides. One of the best tools in its category.

Wish the same router names but different frequencies can be identified during locating them for Evil Twins; otherwise the direction arrow seems flickering seriously in this condition. 5 stars already, but -1 star draws your attention
