What's the best parental control app for android and iphone to track my kids safely?

I’ve got two kids, one with an Android and one with an iPhone, and I’m trying to find something that works on both without breaking the bank or being too intrusive. I’ve tried a few free options but they either missed texts or drained the battery. What are real parents using that actually blocks apps and tracks location without the kids figuring it out?

Look into built-in OS tools like Apple’s Screen Time and Android’s Digital Wellbeing, but for comprehensive tracking and control, I’d recommend mSpy - it works on both Android and iPhone, and it’s reliable and discreet.
