RF 4DAT

RF 4DAT turns your phone into a simple RF awareness tool. Scan the radio signals around you — Wi-Fi networks, cellular towers, Bluetooth devices, and magnetic (EMF) fields — and see them in clear, calm screens. No jargon, no clutter.

WHAT YOU CAN SCAN
• Wi-Fi — every network in range with signal strength, channel, band (2.4 / 5 / 6 GHz), and security type. Spots networks whose names look like cameras.
• Cellular — your serving tower and neighbors: signal in dBm, network type (LTE / 5G), and operator.
• Bluetooth — nearby devices sorted by signal, with genuine tracker detection that flags Find My, Tile, and SmartTag advertisements.
• EMF — a magnetic-field meter in microtesla, the way handheld EMF meters work.

BUILT AROUND PRIVACY — THE 4DAT METHOD
Your scans live on your device by default. There is no account required, no analytics, and no tracking. An optional sign-in lets you back up and sync your history across devices — but it is off unless you turn it on, and you can delete your account and all synced data at any time, right from Settings.

RF 4DAT PRO (one-time purchase)
Scanning is free forever. Pro unlocks the extras: scheduled scans that run on their own, auto-scan when you open the app, on-device Trends insights, and CSV export of your history.

USE IT RESPONSIBLY
RF 4DAT is for understanding the signals in your own space. Use it only where you have permission and legal authority. Device counts are estimates of nearby signals, not identifications of people. Never use it for stalking, covert surveillance, or tracking individuals.
