If you don’t mind your IP address being public, it might work for you. ### 3/5 — Works well enough that it breaks normal functions *2026-08-24, version 6.6.2* There’s some underlying profile that sticks around even after deleting the app that I can’t figure out that’s keeping product preview pages from functioning, breaks normal redirects, and completely blocks AI overviews as well. Not everyone wants that but sometimes it’s convenient. Lots of normal functions are broken though and I can’t figure out where to disable the blocker functions breaking them. Honestly, devs please help ### 3/5 — インターネット異常 *2026-08-17* インスタ、TikTokが開けなくなり1日半獲得してましたがこのアプリを消したら問題なく起動しましたAIによると→ 「1Blocker」 が通信をフィルタリングしていて、InstagramやTikTokの通信までブロックしていた可能性が高いです。 だそうです ### 2/5 — Recent decline in quality - vibe coding? *2026-08-15, version 6.6.1* Worked great for years. However, recently it’s been causing issues requiring a complete uninstall and reinstall to resolve. Most commonly, apps will detect “no network connection” or similar. The ad filtering widget will also completely break, and the app itself becomes unlaunchable. The only fix is to delete and redownload. ### 4/5 — APP USER *2026-08-10, version 6.6.1* Having to reinstall, otherwise the best 5Stars. ### 2/5 — Doesn’t Work *2026-08-05, version 6.6* I noticed that lately the blocker has not been working. It worked great for a while ### 4/5 — La mise à jour change tout *2026-08-02* Il est possible d intégrer des listes de blocage extérieures c’est une belle avancée et il semble qu’il soit également possible d utiliser un serveur dns personnalisé. Bravo au développeurs 👍 toutes les publicités ne sont pas bloquées il faudrait revoir peut être l intégration à l application des listes internes qui ont été choisies. Dernière chose les publicités sur YouTube ne sont pas bloquées il faudrait également revoir ce bug **Developer response:** Thank you for the kind words and for your detailed feedback! 🙏 Regarding YouTube ads: the 1Blocker Scripts extension should keep them blocked in Safari. Please ensure it is enabled in iOS Settings -> Apps -> Safari -> Extensions, as well as in 1Blocker: the Block Ads on YouTube.com toggle in the Ads section of the app. In general, YouTube ad blocking should work well, but since YouTube frequently updates its ad scripts, it can occasionally take a short time for the filters to catch up with their changes. Also, please feel free to contact our support team for more detailed help anytime. We are just one message away: support@1blocker.com ### 3/5 — It doesn’t work (kinda) *2026-07-29, version 6.5.3* The ad blocker works. But at the custom rules, it wasn’t enabled so I did every single step to turn it on, and I went back to the app and it didn’t work. I tried to do it again, but still didn’t work. ### 5/5 — Unique Outstanding Design App! *2026-07-25, version 6.5.3* I have used this unique 5 Star app for many many years! In fact I can remember when the Name change on the App and slowly changed back to the current Name on the App. But I can contend know matter what the Name was the Outstanding App always worked for me it never never did fail me. The Developers have put a great deal of time sweat love and yes Hard Work on the coding of their Software. They surprise me when they added the Firewall protection which has always worked and been a success in a protected system that I as an ole man needed. I have been lucky thru my many years that I got to see Technology change so much and thanks to these Developers that I was going to use some of it! I truly truly appreciate and thank the Developers for all their hard work in keeping up with all the security concerns and corrections that needed to be made on this Software and that they did with all the updates that they did through out the years! So as an ole man I want to Tip my Hat 🎩 to you and say “ Thank’s “ for anyone who read this I Hope you will Download this and give it a try. I Don’t believe you will be disappointed or sorry! I can’t seemingly remember ever being disappointed by this App over the past years I have used it! “ Thank You ! “ 🎩 ### 3/5 — Recent loss of function *2026-07-24, version 6.5.3* As of July 24, 2026 it has stopped working. Ads all over safari. Had no problems for years of use till now. Needs an update. Then, 5 stars. ### 5/5 — This is how Developers can make the internet better *2026-07-17, version 6.5.3* Very nice and well explained. No doubt this is one of the best projects on the platform. Lots of fake reviews ignore. ### 2/5 — wouldn’t recommend *2026-07-12, version 6.5.3* requires “premium” to do anything ### 5/5 — This is the way. *2026-07-09, version 6.5.3* Love it. Completely decimated the scam pop-ups when clicking to watch episodes of The Mentalist on watchthementalistonline .com. 10/10 recommend. ## Most critical reviews (10 lowest-rated) ### 1/5 — Not doing it’s job *2026-09-05, version 6.6.2* I’ve subscribed for a few years now. I copy and paste URLs into Safari and that’s worked out for me…“sort of.” Lately, the ads just keep popping up even though the app is running. It’s gotten really bad in the past few weeks. What’s going on? ### 1/5 — Breaks too many sites *2026-09-05, version 6.6.2* Breaks too many sites, normal things and doesn’t make any easy way to fix. ### 1/5 — Got bad *2026-09-03, version 6.6.2* The app doesn’t block on YouTube anymore. What’s the point? ### 1/5 — It’s Russian. Never use it *2026-09-01, version 6.6.2* They collect your personal data and breach all possible acts like Yandex. ### 1/5 — Not too good *2026-08-20, version 6.6.2* Can’t block a lot of sites they say they do. Difficult to determine blocked or not tabs don’t show status. ### 1/5 — Does not work *2026-07-23, version 6.5.3* This does not block any more ads than the standard safari settings. On Fandom websites, it blocks nothing so it’s pretty much useless. ### 1/5 — Doesn’t Work On Youtube Anymore *2026-07-22, version 6.5.3* Doesn’t block ads on YouTube and YouTube music anymore ### 1/5 — Doesn't work on youtube *2026-07-06, version 6.5.3* Youtube keeps cracking down on adblockers and as of July 2026 1blocker is completely useless on youtube, please fix ### 1/5 — Doesn’t stop ads on apps *2026-06-30, version 6.5.3* Bought premium but ads still come up :( ### 1/5 — Ben *2026-06-13, version 6.5.3* It does not work. ## Most praised reviews (10 highest-rated) ### 5/5 — Great *2026-09-03, version 6.6.2* Great ### 5/5 — I lowkey finally feel safe on websites now *2026-08-27, version 6.6.2* Thank you ### 5/5 — Lifetime purchase *2026-08-12, version 6.6.1* I purchased the lifetime version a long time ago and I’ve never looked back. It’s fantastic. ### 5/5 — APP USER *2026-08-08, version 6.6.1* Solid App. ### 5/5 — Terrific! *2026-08-08, version 6.6* What more can I say?
