BT Notifier

BT Notifier helps you find nearby Bluetooth and Bluetooth Low Energy devices, keep a watch list, and receive local alerts when watched devices appear.

Requires Android 7.0 or later.

Use BT Notifier to:

- Scan for nearby Bluetooth devices and view their names, addresses, signal strength, and device type.
- Add devices to a watch list and give them names you recognize.
- Run optional background scans with a visible status notification.
- Choose the scan interval and duration.
- Limit background scans to times when a selected Wi-Fi network is nearby.
- Hide devices you do not want to see, then restore them later.
- Check monitoring health, recent scan results, permissions, and battery restrictions.
- Browse a local detection timeline and export visible history as a CSV file.
- Find a selected device with a live signal-strength graph and approximate proximity guidance.

Your watch list, aliases, hidden-device choices, detection history, scan settings, and optional Wi-Fi selection stay in the app's private storage on your device. History keeps the latest observation per device per minute for up to 30 days and 10,000 records. You choose where an exported copy is saved. BT Notifier has no accounts, ads, analytics, or developer-operated data collection.

Android requires Bluetooth, notification, and, for some features or Android versions, location and nearby Wi-Fi permissions. BT Notifier uses those permissions for local device discovery, optional Wi-Fi-based scan limits, and notifications. It does not collect or transmit precise location coordinates.

Background scanning depends on Android's permission, battery, Bluetooth, and foreground-service rules. A watched device may not be detected if it is out of range, not advertising, powered off, or restricted by its own privacy settings.

Android filters some Bluetooth Low Energy beacons under the app's Bluetooth permission model. Detection is not guaranteed for every advertising device.

Signal strength varies with walls, interference, and device hardware. Finder proximity is an estimate rather than a distance measurement. Android may require you to reopen the app to resume Wi-Fi-gated monitoring after a restart.
