How Certo AntiSpy works is easy. You make a local backup of your device, and then you let it loose on it. It scans for jailbreaks, looks for spyware, and will warn you if known tracking apps are installed.
Additionally, it also carries out a privacy audit on the apps you have installed, giving you an at-a-glance view of which apps have access to your location, microphone, or camera.
It's quick too, with a scan of a packed iPhone taking a few minutes.
As with most good things in life, Certo AntiSpy is not free. It's offered as a yearly subscription package in three tiers -- Basic is aimed at home users for $29.95 per year, Pro for $49.95 per year, and Ultimate is for at businesses or customers with many devices for $89.95 pear year.
