Worse than free alternatives

$15 a year or just use uBlock Origin Lite which is better anyway. 1Blocker used to be heavily recommended online, long ago, then pulled their paid app and replaced it with this freemium one and its subscription. In that time, uBlock Origin finally arrived on iOS, and it’s still made for maximum efficiency with no greed.

YouTube Ads Not Blocked

I used to love this app, but for the last week or longer, the app is no longer blocking YouTube ads on Safari. This is so frustrating with no fix yet. It doesn’t work on my iPad, MacBook Pro, or iPhone.

Response from developer

Obrigado pelo seu feedback e por usar o 1Blocker! O bloqueio de anúncios no YouTube requer a extensão 1Blocker Scripts. A boa notícia é que a versão 1Blocker 6.7, recém-lançada, traz melhorias significativas nessa área. Por favor, certifique-se de que o 1Blocker está atualizado e siga os passos abaixo: 1. Abra o Safari e acesse Safari > Configurações > Extensões. 2. Ative o 1Blocker Scripts e certifique-se de que está permitido em todos os sites. 3. Abra o 1Blocker, vá até a seção Anúncios e ative a opção Bloquear Anúncios no YouTube.com. Esperamos que isso resolva o problema! Se precisar de mais ajuda, estamos à disposição em support@1blocker.com.

Must have

This is an app that everyone should have up and running. The filtering is top notch, and the developer is active and responsive.

Not Working Anymore

After several years with 1Blocker, which I felt was the best of the limited options available for Safari, I have to say with regret It is now impossible to browse even on popular everyday websites such as Gumtree with 1Blocker enabled - it must be disabled to even view a single page on the Gumtree website. Hundreds of other popular websites are similarly impacted with it enabled, especially news websites in the UK. It has also now completely become ineffective against YouTube ads. Overall I would no longer recommend it.

Best ad blocker out there

I’ve used this for several years and it’s the only ad blocker I need. I watch YT for entertainment, but their ads are invasive, irrelevent, and annoying. This app BLOCKS THEM ALL!!!! And even tho the free version blocks everything, I bought a subscription to support these amazing developers. Thank you, 1blocker.

Powerful 💪

An absolute game changer, paired with a DNS of your choice, it’s a force of nature. Easy to add additional filters.

New challenges ahead

Now that multinational advertising conglomerates are changing their ad domains on a daily basis for some sites, it will be challenging for all the ad blockers to keep up.

iOS27で一気に広告が増えた

iOS27にアップデート後、一気に広告ブロック出来なくなりました。設定は見直しましたが問題なしです。
iOS26までは非常に優秀であらゆる広告をブロックしてくれていただけに残念です。
広告を出す側とブロックアプリ側のイタチごっこの結果なんでしょうが残念です。
課金しているだけに今まで通り不快な広告を完璧に排除していただきたいです。

Hello, we're sorry to hear about this. 1Blocker is expected to work as before on iOS 27, so we are here to help make the app work as expected. Could you reach out to us at support@1blocker.com? We'll be happy to walk you through some troubleshooting steps to get everything working again. Please mention your device model and the version of 1Blocker you're running, as that will help us investigate more quickly. Thank you for your patience and for being a Premium user.

Stopped working

This ad blocker used to be excellent, but for the last month, it has stopped working and now allows ads on websites. It’s still keeping them off YouTube, but that’s about it. I have the paid version, but that hasn’t made a difference. Having ads pop up is very distracting, since they are relentless and extremely annoying. This is NOT what I’ve paid for. If it’s not fixed, I would like my money back.

Blocks websites

I downloaded this as an alternative to Nord VPN, and this is WAY better! I can block specific websites that auto pop up from specific apps and web pages. (I.e. temu). I don’t get ads where I normally would. Now I just need to figure out how to stop ads in apps!

It’s also user friendly. Nord vpn is very technical and if you’re technology challenged like I am, you end up making mistakes that block too much or nothing at all. It’s not easy to understand. 1Blocker is.

If I were to submit feedback, block app ads. That’s it!
