1Blocker Overview

What is 1Blocker? 1Blocker is a content blocker app that allows users to block ads, trackers, and annoying elements on websites. The app is easy to use and provides automatic cloud updates to its built-in filters. It is a fully native app designed to extend Safari naturally and is lightweight, not draining the device's battery. The blocking is super fast because Safari does it itself, and sites load on average 2-5x faster. The app is secure and private, and the only way the developers make money is through direct sales of the app in the App Store. 1Blocker is highly customizable, providing the possibility to create powerful custom rules, and is available on all devices. The app has been featured in various press outlets and offers some features for free, including the ability to enable one category and whitelist synchronization between devices via iCloud. The app also offers friendly support and has been consistently improved over the past five years.

Software Reviews and Criticism

  • By Kubisuro

    Works perfect

    Many OTHER ad blockers have fallen into disrepair, not having been updated in ages or at least visibly updated and losing their effectiveness. This one bucks the trend and goes full throttle ad blocking with great configurability such as easy white listing. I only wish that some websites that I visit and enjoy had ads that weren’t so utterly obnoxious that they hijack my Safari with a new page to announce “You’ve own a prize! Click OK!” And then I can’t find my way back because swiping back just loads the ad again. UGH. Well, this blocker effectively stops that crud with the latest policies. I’m sure it is a full time job just keeping that up to date so the app cost is perfectly reasonable. Technically the app is above all the rest since they’ve managed to implement more than 50,000 policies using a modular system. Awesome. Now if only websites realized their ads were so obnoxious that JUST MAYBE less obnoxious ads would result in less ad blocking and more revenue.......

    Perfect for what I need

    For those having difficulty enabling the content blocking in Settings, you probably have the native content blocking in iOS enabled under the Screen Time section in Settings. Just go to Settings then Screen Time then Content Restrictions, and disable Content Restrictions *there*, under Screen Time. THEN go to Settings>Safari>Content Blockers and now, after you disabled Content Restrictions under Screen Time, you should now be able to ENable the Content Restrictions this app (and any other) provides. It’s counterintuitive yes but that’s just how it works now. Anyway after doing all that, this app works awesome. No more annoying (and arguably pornographic) “Suggested Content” at the bottom of virtually every website! Which is exactly what I was looking to do! Thank you this is such a huge help and now pages load much faster to boot!

    Paid decent app turned into subscription crippleware

    UPDATE: after running into issues following the devs’ reply below, I contacted them directly. Issue hasn’t really been fixed as such but at least most of the functionality CAN be recovered: Go to Settings -> “Premium” even if you do NOT (want to) subscribe -> almost at the bottom, left is a tiny Restore Purchase link -> click & IGNORE PURCHASE ERROR MESSAGE(!): (re)enabling more than one filter should now work anyway. Thanks to Cloud Sync (enabled by default) seems like all my connected devices have then been updated as well. Rating updated now - under the assumption that filter updates will continue to be at least included once in a while with App updates... ====== Original Review ====== I have been a paying supporter since 2015, had no issue paying for the new version in 2018, and would have happily continued with paid upgrades! But as I just installed it on a new device, I find there is no “Restore Purchase” option anywhere, and instead this has been turned into yet another endless-payments “freemium” piece of crippleware! <SNIP rant-y bit> If you want constant payments for constant filter updates (which I’m not interested in), maybe, but disabling existing paid functionality deserves a ZERO Star rating. But the cherry on this {bleep}pie is the unwanted pop-up in my (ex) paid app ASKING ME to give you this review.

    Works As Advertised Despite Steep Price

    I will admit I paid a steep price for the ad blocking app. Compared to others out there on the App Store, this is the most expensive app I purchased specifically for ad blocking purposes. This app works very well and performs as advertised. I would say this app resembles UBlock Origin, the best ad blocking internet extension on PCs and Windows. Two reasons: First, you can hide certain elements of a website you do not like. And second, there are so many filters you can enable on this app. If you're willing to spend a bit more money compared to others, you will not be disappointed. I am using this app on a 10.5'' iPad. Hopefully, this app will get updated regularly. Also and for others wondering, THIS DOES NOT BLOCK ADS IN APPS. You need to use the app called Ad Blocker to enable that.
