A PIN they can't get past
You set a four-digit PIN on their phone. Every setting sits behind it. They can't loosen the rules, turn it off, or quietly extend their own limits.
On Instagram and TikTok, most of what your child watches was not posted by anyone they know. It comes from accounts they have never heard of, chosen by a system that is measuring what keeps them watching. ReelBlock switches that feed off and leaves the rest of the app alone.
Nothing about your child is uploaded, stored on a server, or sold. There is no account to make.
A child's friends, their group chats and the accounts they chose are the safe part. The risk sits in the recommender: the Reels tab and the For You page, where an endless queue of strangers arrives without anyone asking for it. That is the route by which content about self-harm, disordered eating, extreme views and adult material reaches children who never went looking for it. It is also the part of these apps that no parental control in iOS or Android can reach, because from the outside it looks like ordinary app use.
Screen time limits treat every minute the same. An hour of messaging friends is not an hour of algorithmic video. ReelBlock closes the door the strangers come through and leaves the rest open.
Set up in about five minutes on their phone.
You set a four-digit PIN on their phone. Every setting sits behind it. They can't loosen the rules, turn it off, or quietly extend their own limits.
Their friends always get through. Beyond that, only posts matching words you approve. Football and revision, yes. Whatever the algorithm served a fourteen year old at 2am, no.
Set the hours. Outside them the apps simply don't open. No negotiation at 11pm, because there's nothing to negotiate with.
How long they were on, and how many pieces of stranger content were stopped before they reached them. Built on their phone and read on their phone. It never leaves the device.
Not a scare tactic, just arithmetic. Thirty days a year, every year, from now until they're eighty. Most teenagers are well past two hours. ReelBlock does the sum with their real numbers, and shows you how much of it you've taken back.
It doesn't read their messages. It doesn't track where they are. It doesn't send you a feed of everything they look at, and it doesn't send that anywhere else either. Surveillance and safety aren't the same thing, and a teenager who feels watched finds another phone.
It also isn't a content filter that reads and judges each video. It works one level up: it stops the app serving your child video from people they never chose, which removes the delivery mechanism rather than playing whack-a-mole with what it delivers.
ReelBlock changes what the algorithm is allowed to put in front of them. That's the whole idea.
Five minutes on their phone and a PIN only you know. It keeps working without you checking it, and one setup covers every child in your house.
Download the app, then turn on parent mode inside it.
