We’re releasing Survey, a native macOS tool that shows you what your computer reveals about itself through Bluetooth, WiFi, location services, and the radio spectrum.
What it does
Your Mac is constantly broadcasting and receiving signals. Bluetooth beacons from nearby trackers and smart glasses, WiFi probes from networks around you, location data leaking through permissions you may have forgotten about. Survey makes all of this visible.
It has four tabs:
- Bluetooth — scans for nearby BLE devices using a database of ~130 device signatures. Categorizes what it finds (trackers, glasses, wearables) and assigns threat levels. High-threat devices trigger desktop notifications.
- WiFi — grades your current network’s security (A-F), fingerprints the access point type, scans nearby networks, and audits your saved networks against ~90 known suspicious SSIDs.
- Location — computes a privacy exposure score based on your permissions, Bluetooth state, and network security. Maps your location history and links to macOS privacy settings.
- SDR — with an RTL-SDR dongle, explore the radio spectrum from 24 MHz to 1.7 GHz. Real-time FFT visualization, signal classification, and FM/AM demodulation.
Why not just block everything?
Survey isn’t a blocker. It’s a visibility tool. You can’t make good privacy decisions without first understanding what’s happening. Survey shows you the landscape — which devices are nearby, how secure your network is, what your location permissions expose — and then you decide what to do about it.
This is the same philosophy behind Tapped, our network visibility tool. Tapped shows you where your Mac is talking on the network. Survey shows you what it’s broadcasting and receiving over the air. Together, they cover the full picture.
Privacy first
Survey makes zero network requests. No analytics, no telemetry, no data leaves your machine. All scanning data is stored locally in SwiftData and can be exported as JSON or cleared with one tap.
