iPhone, record phone call app. non jail broke phone

[Zarken]

Anyone have any recommendations on free or low cost apps that work to record phone calls? Or a method that would work best?
In Kentucky, its legal if one side knows it's recording.

Short story. Friend and his wife are divorcing and she is going nuts on the phone calls, admitting all kinds of crazy stuff. So he wants to record the calls because she admits to telling a lie to obtain restraining orders and getting her friends to lie as well. They have kids and he is not permitted to see them because of it. So he wants the calls recorded to take to his lawyer and go from there.

Any help is appreciated.

Get a Google Voice account, you can screen and record calls. It also translates the calls to text.

That works OR get a pickup that suction cups to the phone, those work surprisingly well.
