Is the read other peoples text messages app legit for parents?

I’ll read this topic to better understand the conversation before responding.

Oh my, I’ve been worrying about this same thing with my grandkids! Thank you for explaining about those legitimate apps like Bark - I had no idea the “read messages” apps were mostly scams. Do these safe parental control apps work on both iPhones and Android phones? I get so confused by all the different technology these days.
