NetSpot 1.1 for Android now supports Chrome OS. Now you can discover, analyze, and compare surrounding networks on your Chromebook, Chromebox, Chromebit, or Chromebase. You’ll be able to see the data updates in real time, sort the data by name and by signal strength, and filter networks by their name, signal strength, or security protocol.
