Signal Mapper can plot Wi-Fi/Bluetooth/cell signal coverage on an auto-generated blueprint of your room in real-time.

Easily create a blueprint that shows where your signal is strongest.
Signal Mapper provides detailed Wi-Fi information for 2.4GHz & 5GHz networks including SSID, BSSID, and encryption status.

Collect information on all nearby networks simultaneously!

Switch between networks at any time to compare coverage between different devices. Finding the perfect spot to place your router has never been so easy!

Visualize your signal strength in first person perspective!

Signal Mapper runs on Google’s Tango Technology – the first commercially available mobile AR platform. The application uses multiple cameras and inertial motion sensing with Simultaneous Localization and Mapping (SLAM) data fusion techniques to construct a 3D model of the user’s surroundings in real-time as they move through their environment.

Features at a glance

  • Detect 2.4GHz & 5GHz Wi-Fi networks
  • Displays Wi-Fi SSID, BSSID, and encryption status and device manufacturer
  • Detailed meter and historical graph view of selected signal
  • Easy to read blueprint and heat map visualization
  • First-person AR view
  • Ultra HD Screenshots – 4k, 8k, and beyond!
  • (Bluetooth and Cell coming soon!)

Outlets including Engadget and PocketNow have named Signal Garden’s Signal Mapper utility the best commercial app for Tango, and Johnny Lee (Google, Tango Engineering Director) featured the app presenting Tango during the Google IO 2017 AR/VR Keynote.

You can do things like walk around your house with the tracking sensors and depth sensor to generate a heat map of the Wi-Fi signal strength within your apartment or in the building. And this actually lets you find dead spots, or where you might want to put the router, or even buy a repeater.

My favorite utility so far is Signal Mapper, which builds a blueprint of your home or office, showing where your Wi-Fi is strongest and weakest.

One of my early favorites is Signal Mapper, which prompts you to wander around and visualize how strong your Wi-Fi signal is (future versions will support cellular networks, too). Keep at it long enough, and you're left with a signal-strength heat map that doubles as a rough blueprint of... wherever you happen to be.
