### 5/5 — Works great

*2026-07-07, version 2.2.0*

Works great and it’s free and open source!

### 1/5 — Did not work on Safari, at all.

*2026-06-05, version 2.1.0*

Did not work on Safari. Gone thru all settings and applied. Did not work at all.

### 5/5 — Just enough and out of the way of the user!

*2026-05-25, version 2.1.0*

Simple to use and not constantly annoying! 
If it misses some-things how am I supposed to know these things. Im not a programmer!
Sales pitch of other software relies on us dummies!!!! Some webpage content can not be blocked so don’t bash this product unless you understand this concept! Looking at you Youtube! Lol..

Thanks Alexander for this simple and effective software.

### 5/5 — Best available option

*2026-05-24*

I’ve used uBlock lite, Wipr2 and some other options. This is currently the best option for adblocking on iOS and the closest to the functionality of uBlock Origin on desktop. Element hider actually works!

### 1/5 — Didn’t even work for a minute

*2026-05-23, version 2.1.0*

The very first website I went to had ads.

### 5/5 — A Spectacular FOSS AdBlocker!

*2026-05-20*

This has to be one of the best AdBlocker solutions for Apple platforms. And an even bigger bonus that it’s FOSS (free and open source)! Plus its filter rules update independently from the app, which means updates can come quicker than uBlock Origin Lite on iOS! A must download for anyone needing a reliable AdBlocker on Safari.

### 5/5 — 自定义脚本问题

*2026-05-20, version 2.1.0*

开发者您好！请问自定义脚本在那下载？支持哪些格式？有官方论坛，TG类似的官方讨论平台吗？谢谢！

### 5/5 — Best available

*2026-05-19, version 2.1.0*

This is by far the best adblocker available on iOS.

### 5/5 — Incredibly Effective at Blocking YouTube Ads

*2026-05-18, version 2.0.3*

I’ve used uBlock Origin Lite since it just became available for iOS and, while it’s a fine Adblock in its own right, wblock just works better for YouTube. wblock just blocks all the ads without breaking the page. With UBOL I would often have to refresh the video for it to properly load. Not with wblock, which is more effective and efficient overall. It’s become my go-to ad blocking app and I’m thankful to the developer for making it available to all of us for free.

### 5/5 — Beyond useful

*2026-04-22, version 2.0.2*

Super props to this developer.  The VERY BEST blocker available.
