How to Block Channels on the YouTube App (Phone & Tablet, 2026)

The YouTube app on your phone gives you almost no control over channels — there's no block button, and you can't add one. But you're not stuck with the feed YouTube hands you. Here's what actually works on mobile in 2026.

What the app lets you do

Inside the YouTube mobile app, your only native levers are:

• "Don't recommend channel" via the three-dot menu on a video — a weak, temporary signal that YouTube reintroduces after a few weeks.
• A restricted or kids profile for broad parental filtering — not per-channel.

There is no per-channel blocklist in the app, and because phone apps are sandboxed, you can't install a browser extension to add one. So how do you reduce a channel on your phone?

The account-level trick

Here's the key fact: "Don't recommend channel" is attached to your Google account, not to one device. Whatever you train on one signed-in device follows your account everywhere — including the app on your phone.

So the reliable approach is to do the work where you have control — a desktop browser — and let it propagate:

1. On desktop, block or "don't recommend" the channels you don't want.
2. As long as your phone is signed into the same Google account, YouTube recommends those channels less in the app too.

It's a reduction, not a hard block — but it meaningfully cleans up your mobile feed without touching the phone at all.

Automating it with Blokari

Doing this by hand, channel by channel, is slow and it resets. Blokari automates the desktop side: as it blocks channels — your own picks, or whole curated categories like propaganda, AI farms, clickbait, and gambling — it can automatically send YouTube's account-level "Don't recommend channel" signal for them, and keep reinforcing it as channels resurface.

The practical setup for a cleaner phone feed:

1. Install Blokari on a desktop browser and enable the categories you want gone.
2. Let it hide them on desktop and train your account.
3. Keep your phone signed into the same Google account.
4. Over the following days, those channels fade from the app's recommendations too.

For kids on a phone

If the goal is child safety on mobile, combine YouTube Kids or a restricted profile on the phone (the strongest on-device control) with Blokari's free parental categories trained on desktop. Together they cut far more than either alone — see the free parental controls guide.

Bottom line

You can't install a blocker inside the YouTube app — but you don't have to. Train your Google account on desktop, keep your phone on the same account, and the unwanted channels quietly recede from your mobile feed too.
