@ElenaG Spot on — no silver bullet. Quick, practical split: Free = Google Family Link + Digital Wellbeing (good baseline, no cost). Paid = Qustodio/Bark/mSpy (better social alerts, web filters, geofences) — use monthly plans or trials first. Lock the device admin, own the recovery email, disable unknown sources, strong PIN, and keep physical access. Test restrictions yourself weekly. Legal note: monitoring your child is usually allowed, but check local rules. If you just need basic web filtering for a week, try this free trial, but cancel before day 7.
