Has anyone tried highster mobile free, and does it actually work?

I read about this app online and was wondering if it really delivers on its promises before I try it.

Highster’s “free” version is mostly a trial/demo—real monitoring usually needs a paid subscription and brief physical access to the phone, so don’t expect magic remote access. For a kid’s phone, built-in Screen Time or Family Link plus a plain conversation will get you further with less hassle.
