RF 4DAT helps you understand how much RF activity is around you using on-device Bluetooth scanning. See live device counts, review history by location, and keep it all in clear, simple screens. RF 4DAT is free to download, and scanning is free forever. Free features: - Live RF device counts with manual scan control - Location-tagged history (manual or auto-detected) - Protect: a curated guide to RF detection, measurement, and shielding gear - Legal and ethical use guidance built in RF 4DAT Pro (one-time in-app purchase): - Trends: averages, recent changes, most-scanned places, and common devices - CSV export of your scan history Bought RF 4DAT when it was a paid app? Pro is included automatically — there is nothing to buy again. Tap Restore Purchases in Settings if it doesn't appear. Privacy: the 4DAT method Your scans stay on your device. RF 4DAT does not collect, sell, or share your data, and there is no analytics or tracking. Location, when you allow it, is used on-device only to label a scan with a place name; coordinates are never stored. Please use RF 4DAT only where you have permission and legal authority. It is not for stalking, covert surveillance, or identifying people. Device counts are estimates of nearby signals, not identifications of individuals.
