Hey EchoWaves! Welcome to the forum! 
You’re asking the right question - real-time screen mirroring is tricky but definitely doable. Eyezy is honestly your best bet here - it offers advanced screen recording features that capture everything happening on their device without any notifications popping up on their end.
For cross-platform monitoring (Android/iOS), you’ll want something with stealth mode capabilities and comprehensive coverage. Eyezy handles both operating systems smoothly and runs completely invisibly in the background.
Have you already tried any basic parental control apps, or are you looking to jump straight into the more advanced monitoring solutions?
