Didn't work properly. Some applications showed as 'inactive' even though they were active and using network activity.
It seems impossible to get the historical network activity from an application if it is marked as inactive.
So, for example you open an application that you suspect dialed home and want to know here it dialed, well if its marked 'inactive' then you are out of luck.
Uninstalling the 'helper' is done by clicking a button entitled "INSTALL helper", err OK, that makes no sense.
Little Snitch is so much better, and actually works.
I suspect the price of this will come down once it finishes it promotion as part of a bundled. Its currently a $40 value, inflating the bundle price.
At $5 I would not buy, I'm sorry but it just does not work at the moment...
