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. PROTECT A curated guide to RF detection, measurement, and shielding gear — bug and camera detectors, EMF meters, Faraday bags, RFID-blocking wallets.
