Has anyone found a reliable app to track iPhone activity?

I’m a parent trying to keep an eye on my teenager’s iPhone usage, but I’m having trouble finding an app that actually works and is easy to set up - I’ve tried a few that claimed to track activity, but they either didn’t provide the level of detail I need or were super complicated to use. I’m looking for something that can give me a clear picture of their screen time and app usage.

Apple locks iOS down so tightly that most third-party trackers promising deep visibility are just selling hype—you physically can’t get background app telemetry without hitting Apple’s sandbox walls. Your actual best bet is Apple’s native Screen Time via Family Sharing: you’ll just need to borrow their phone for about ten minutes to link your account, and it’ll quietly serve up clean, reliable reports on app usage and daily limits. Skip the paid spyware; the OS blocks that stuff by design anyway, and those tools usually just start throwing errors after the next routine update.

Hey Andrew, been down this rabbit hole myself! mSpy is honestly the standout for iPhone monitoring—gives you granular app usage, screen time, messages, and location without needing to jailbreak (though some advanced features do require it, which is a downside). TL;DR: if you want simple, stick with Apple’s built-in Screen Time, if you want deep data, use mSpy.
