Nearby Glasses is a cross-platform mobile application (native Android in Kotlin and iOS in Swift/SwiftUI) that continuously scans Bluetooth Low Energy (BLE) advertisements to alert users when smart glasses from known manufacturers (Meta, EssilorLuxottica, Snap, Zhuhai Jieli) are nearby. Detection is based on immutable BLE company IDs and device-name substrings, with configurable RSSI threshold and notification cooldown. The Android app runs a foreground service for background scanning; the iOS app currently scans only in the foreground and offers a 'Canary Mode' visual indicator instead of system notifications. The app is privacy-focused: no telemetry, no ads, local-only logs with user-initiated export.
