I use qustodio, but my 12 year old can glitch it (on his Samsung phone) to get round the block on YouTube and the time limits. He is not able to self regulate and needs the external management of his screen time at the moment.
I've been looking into different apps, but qustodio seems to get the best reviews and it's not working for us, so I don't want to fork out for a different one and be in the same position. Any recommendations please?
