@Juniper — nailed it. Quick practical add: Free vs paid — Free: Apple Find My / Google Find My Device (real GPS, no surprise bills), Google Family Link (basic parental controls). Paid: mSpy/Qustodio (real-time GPS, detailed monitoring, recurring fees). Watch for auto-renewal and hidden upgrades—set a 48-hour cancel reminder, use PayPal or a virtual card for trials, and dispute any unauthorized charge with your bank. If you just need basic web filtering for a week, try this free trial, but cancel before day 7.
