This tool comes in very handy when you want to make sure that you're connected to a specific AP.

Please note! this application does not drain your battery!
It only uses events from the systems (that's why the signal level indicator only updates once in a while).

It has two modes:
1. showing the information in large font.
2. showing extended data in smaller font.

Tap on the widget to switch between modes, when the device is connected to an AP.
