If you just want to locate your phone, or your child's, or your employee's company phone, you can use Apple's or Google's built-in tracking; a third-party app is unnecessary.
If you want to directly monitor a child's or employee's usage, and/or restrict them from some sites/apps/settings, you probably want a parental/employer control app that doesn't compromise the phone to hide itself.
