It's a fairly new app, so you'll probably won't find lot's of content/reviews about it online yet.
I have tried the free iOS version for half a year or so on my iPad and it worked pretty solid. During the holiday season a couple of weeks ago they had a special sale so you could buy the in-app iOS purchase + Mac app for 5,- in total. Bought it of course because I was so curious about the Mac version and I have to say it works like you should expect from any other Mac + iOS app with iCloud sync.
The Mac app will give you two Safari extensions. One for blocking content and the other for adding your own rules to the blocking system. The last one I haven't activated, I like it as is, straight out of the box, only activated the blocking extension and it does it thing for me.
Do know, this probably only works with Safari!
What I like most about this is.
- It's premium, it cost you a few dollars you normally
should donate via PayPal to open source projects like this but for some reason you never do because free stuff is free and free is free. Strange how that works, I know.
- They won't let some 'fair' ads sneak through on a regular base like AdBock does. Reason why I switched to uBlock before.
- This is better than uBlock because of iCloud sync and the entire experience/workflow. You'll get iOS + Mac apps from one single team/company. Change a setting on your Mac and it also gets changed or updated on your iPhone and iPad. This is how apps in general should work on all Apple's OS' so yeah, this is totally in my opinion the best experience for any AdBlocker system.
- Did I already mentioned it works via native iCloud? No 3rd party accounts or logins with any social media account to get stuff done.
Negative stuff I found.
- After installing the Mac app you probably have to restart you Mac before it works.
- It doesn't block
everything online, there are probably free extensions like uBlock out there that will block everything you can imagine, they will even get rid of your mother in law, but hey, I don't visit the entire internet so if this means my 1Blocker-script will be much smaller in the browser and that way more lean and mean against other scripts that block anything out there, I'll take it. When visiting my day to day sites I've never seen a site that didn't got blocked by default. I did noticed tho, when visiting some 'xxx adult' sites, it doesn't block those freaking ads, but you could add them to your own custom rules of course. It doesn't trouble me at all because I do not visit those sites on a daily base.
Last; the price went up after the holidays.
Before the regular price was 8 or 10.- for both apps - I bought it for 5.- during the holidays and now it's 15.- to get them both. I don't know if 15.- is fair, everybody should decide for themselves. I like to compare app prices to other apps on my system and how often I use them. If three Things (ToDo) app costs you about 99.- and you're willing to pay for that, this 15.- will probably be peanuts but I can understand if students think 15.- is a lot of money for a blocking script and getting a nice native workflow on both systems.
Both apps do get fairly updates so it's actively in development with is good!
