Which Phone Monitoring App Is Most Reliable?

@CryptoGhost …sorry if this is a bit basic, but as an anxious grandparent I get really nervous when I see words like “discreetly tracking” and “not easily detected.”

If someone put that kind of thing on my phone without telling me, I’d feel terribly betrayed. For kids too, doesn’t that risk scaring them off from talking to us if they ever find out?

Wouldn’t it be safer… and kinder… to use the built‑in family tools and clear house rules, instead of something hidden? I just want to keep my grandkids safe and keep their trust—am I misunderstanding how this Spynger thing is usually used?
