SentryRF:AI Counter Security Scanner
Hi HN, I built SentryRF because I was frustrated by the lack of granular control on Android for identifying unwanted tracking devices. While Google's native "Unknown Tracker Alerts" are a good start, they often feel like a black box with limited diagnostic tools. The Tech: Signal Analysis: Instead of just listing every BLE/wifi device, SentryRF uses signal strength (RSSI) and temporal patterns to distinguish between a "passing" device (someone walking by with an AirTag) and a "following" device (a tracker on your vehicle), even peeping-toms. Hardware Sensors: I’ve integrated the…

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…from sentryrf.com

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986.
