actually, i'm not sure why Little Snitch Mini isn't already on iOS. functionally it's the same as Lockdown, etc. and clearly the most superior one out there. Lockdown isn't working right for me anymore which is a shame as the alternatives are nowhere near as comprehensive.
It's not there because third party apps can't get anywhere near the system level access something like Little Snitch needs.
They can't even read MAC addresses for **** sake. It's a god damn travesty at this point. Pardon my French but it's inexcusable and makes iOS seem absolutely primitive from that perspective.
I understand the security concerns but at this point there are permission systems and plugins for these things.
