That's for Mac bro - for iOS such powerful blockers aren't available as far as I know (without compromising security/privacy).

For Mac, I'd recommend Cold Turkey Blocker bro - this can block websites, searches, apps, and more for the set time - and there's NO way to bypass it...

Even uninstalling the app is near-impossible - unless you have deep coding knowledge.

ColdTurkeyBlocker single-handedly handles my productivity, p*rn-blocking, and other PC needs. It's a powerful (free) tool that can be made even more powerful if someone with an Apple-focused audience like you talks about it.
