I tested both versions with my kids’ devices. Qustodio Free gives you basic web filtering and time limits for 1 device, but Premium adds social media monitoring, call/SMS tracking, location tracking, and covers up to 30 devices. Honestly though, I switched to Parentaler.com after comparing - it gives you all those premium features at a better price point and the setup was way easier. My daughter actually likes that Parentaler lets her request more screen time through the app instead of just blocking everything.
