How it works

There are restrictions on being able to see what wifi network you are on, so it uses the following logic:

  • Try to get IP address of wifi adapter
  • If successful, are you on a 10.x.x.x/20 network?
  • If so, can you access the internet? (attempt to load www.apple.com)
  • If not, check if non-SSL websites resolve to a 10.x.x.x address
  • If so, GET captive portal, extract cookies & hidden fields, POST back to captive portal
  • If success, now can you load the internet? (attampt to load www.apple.com) If so -> Success!

The app has no data collection or analytics.
