ShadowTrail - Tracker Detector

Brandtson LLC

About this app

ShadowTrail is your personal security companion that scans for suspicious Bluetooth and WiFi devices in your vicinity, alerting you to tracker tags, smart glasses, GPS tracker hardware and other surveillance-capable devices that may be following you.

🛡️ ADVANCED TRACKING DETECTION
• Real-time scanning of Bluetooth and WiFi devices around you
• Intelligent algorithm detects devices that keep pace with you as you move
• Checks GPS accuracy before trusting your movement, so standing still doesn't trigger false alarms
• Recognizes 44,000+ hardware devices
• Sorts what it finds into 21 device categories
• Monitors signal strength, spread and movement patterns

🕶️ SMART GLASSES ALERTS
• Camera-capable eyewear gets its own section at the top of the list
• Optional sound and vibration the first time each pair is seen
• Recognizes Ray-Ban Meta, Snap Spectacles, Vuzix and RayNeo
• Mute for the rest of a scan with one tap

🔍 DETAILED DEVICE INFORMATION
For every detected device, view:
• Device name, category and type (Bluetooth/WiFi)
• Manufacturer identification
• Signal strength, spread and estimated distance
• Whether it is moving closer or further away
• Tracker, smart glasses and GPS-hardware ratings — with the evidence behind each one, and what ruled a device out
• Raw technical data for experts
• Signal spread and trend across recent sightings
• Recognizes common tracker brands: AirTag, Tile, Samsung SmartTag, Chipolo, eufy, Filo

🔒 PRIVACY FIRST
• All scanning happens locally on your device
• No data sent to external servers
• No account required
• Location data never leaves your phone

⚠️ WHAT IT CAN'T DO
Being straight about this matters:
• It can't see a device that isn't transmitting
• It can't tell whether a camera is recording
• A vendor ID names a maker, not a product, so ratings are graded rather than absolute
• Distance is estimated from signal strength and is a rough guide

What’s new

• Smart glasses detection, with optional sound and vibration alerts
• Rebuilt distance estimates — WiFi and Bluetooth are modelled separately, so ranges are much closer to reality
• Far fewer false "following" alerts: GPS drift while standing still no longer counts as movement
• 21 device categories, from hearing aids to smart locks
• Every rating now shows its evidence and what ruled a device out
