SentryRF: Anti-Spy Detector Tracker

The app converts an Android phone into a counter‑surveillance scanner by using its built‑in sensors to detect a wide range of wireless and electronic devices. It runs eleven on‑device AI models plus a lightweight Gemini Nano model to identify hidden AirTags, GPS trackers, spy cameras, drones, rogue Wi‑Fi networks, fake cell towers and other stalking hardware. Scans produce visual heat maps, haptic alerts and EMF pattern classification, while a learned knowledge base helps distinguish familiar devices from suspicious ones.

Typical users include individuals who suspect they are being tracked in personal, vehicle or residential settings, as well as travelers concerned about hidden cameras or counterfeit Wi‑Fi at hotels and airports. The software can perform room‑scale sweeps, focused vehicle checks and real‑time monitoring of nearby wireless activity, flagging unknown or out‑of‑place devices and recording evidence for later review.

All processing occurs locally on the phone, with no cloud connectivity or user accounts, ensuring that detection results remain private. The tool supports recognition of thousands of device types across multiple protocols and provides continuous, AI‑driven alerts to help users respond to potential surveillance threats.
