How to Block Apps When Your Child Uses Your Phone

Short answer: use Android's app pinning. It locks your phone to the one app you choose until you unpin it with your PIN — no other apps, no browser, no home screen.

Settings → Security → App pinning, and switch on "Ask for PIN before unpinning". Four seconds each time you hand the phone over.

The actual problem

Your child wants the phone for a science project, or twenty minutes of video while you finish cooking. You hand it over, and eight minutes later they're somewhere else entirely — YouTube autoplay, a game, your WhatsApp.

The instinct is to install a parental control app. Don't, on this phone: every one of them, ours included, supervises the device, not the person. Whatever limits you set for your child apply to you the moment they hand it back. That's the mistake to avoid, and it's why so many parents install one of these and remove it a week later.

What you want is a temporary lock, not a permanent policy. Android already has one.

App pinning, step by step

Set it up once:

1. Settings → Security (or Security & privacy)
2. Find App pinning — on Android 8 and older it's called Screen pinning
3. Switch it on
4. Switch on "Ask for PIN before unpinning"

That last step is the entire feature. Without it, holding two buttons unpins the app and your child is out.

Then, every time you hand the phone over:

1. Open the app they need — YouTube Kids, Google Classroom, Vedantu, the calculator
2. Open the recent apps view (swipe up and hold, or the square button)
3. Tap the app's icon at the top of its card
4. Choose Pin

The phone is now that app and nothing else. No notification shade, no home screen, no browser, no switching. To end it, hold back and overview together and enter your PIN.

What it does and doesn't cover

It does: stop app-hopping completely, survive a determined ten-year-old, work on every Android including budget Xiaomi, Realme, Samsung and Oppo, and cost nothing.

It doesn't: allow two apps at once — so a project needing Classroom and a browser doesn't fit. It doesn't filter content inside the app they're pinned to, which is why YouTube Kids rather than YouTube matters. And there's no schedule; you do it each time.

For handing over the phone for video

Pin YouTube Kids, not YouTube. Curated content, a built-in timer that locks the app when it runs out, search that can be switched off entirely, no comments, and a passcode on the settings.

Pinned YouTube Kids with a timer is about as good as a borrowed phone gets, and it's free.

If they need more than one app

Two options, both imperfect.

A second user profile — Settings → System → Multiple users. A separate space with its own apps and its own accounts, so your things aren't there at all. Genuinely the best answer where it exists, but a lot of budget phones from Xiaomi, Realme and Oppo hide or remove it. Check before relying on it.

Guest mode, where your phone offers it, does something similar with less setup and less control.

The honest limit of all this

None of it is supervision. You'll get no report of what they did, no filtering of what they saw, and no protection the moment the phone isn't pinned.

That's the real ceiling on a shared phone, and no app removes it — including ours. ParentalEdge doesn't currently have a shared-phone mode, and we'd rather tell you that than sell you something that locks down your own device.

When your child has a phone of their own — a hand-me-down counts, and it's how most families start — the picture changes completely: filtering across 31 categories in every browser including incognito, Safe Search on five engines, around 260 risky apps blocked from the first minute, bedtime, daily limits, and reports of what was actually watched and searched.

Frequently asked questions

Can't I just install a parental control app on my phone?
You can, and it will apply your child's rules to you. Time limits, bedtime, blocked apps — all on your own device, all day. It's the single most common mistake here.

Does app pinning work on budget phones?
Yes. It's core Android, on essentially every phone in use.

Can my child unpin it?
Not without your PIN, as long as you enabled "Ask for PIN before unpinning". That toggle is doing all the work.

What if they need a browser for homework?
Pinning won't cover it. A second user profile is the better fit if your phone has one; otherwise sit nearby, which at that age is a reasonable answer.

Is there any way to block adult content on a phone we share?
Not per-person. You can point your home Wi-Fi at a family DNS filter like CleanBrowsing, which covers every device in the house — including mobile data, no. It's partial, and it's better than nothing.
