iPhone analytics displaying remote access that I never granted

RTbuddyv2 is from an app I never downloaded and I want to know why it’s showing up along with my ex fiancé just happening to know my whereabouts 24/7. Can you look over my analytics and tell me if that’s happening or do I need to take it elsewhere?
