My friend just had someone install some looping GPS tracking device without them knowing, they were able to see everything they were typing and calling and see exactly where they went by GPS. What is the program called and how do I uninstall it off her phone?

The only thing that I know for sure is that your FMS must be approved for GPS approaches. I thought that you also need some kind of annunciator in the cockpit telling you that the GPS has gone into the more precise approach mode. I fly a Lear 55C with dual UNS 1-Ds.
