I installed TurbySpy on my teen daughter's iPhone 11 for security. Though I was not able to get the app to function as advertised the TurboSpy team was helpful in trying to correct the matter and ultimately providing me with a timely full refund.
Tip for consumers: Monitoring children's iPhones is tedious. I had not had success with several programs but TurboSpy really tried their best and did provide a timely full refund. I've had other companies refuse.
