How to Block Apps on iPhone

To block apps on iPhone, use an app blocker built on Apple's Screen Time API, such as SupaFocus. Grant Screen Time permission once, select the apps to block, and start a focus session or schedule — the apps are then blocked at the system level and show a block screen instead of opening.

Why blocking beats willpower

Deleting apps doesn't work — you reinstall them in 30 seconds. Grayscale mode and “mindfulness” reminders don't work either, because the app still opens. What works is friction: when Instagram physically won't open, your brain stops asking after a few days. That's why the most effective way to block apps on iPhone is a system-level blocker, not a habit tracker.

Your options for blocking apps on iOS

Apple's built-in Screen Time limits — easy to set, but also easy to bypass: the “Ignore Limit” button is one tap away.
Deleting apps — reversible in seconds, and you lose your accounts, drafts, and settings.
A dedicated app blocker like SupaFocus — uses the same Screen Time API as Apple, but adds commitment levels so you can't talk yourself out of the block, plus schedules, daily limits, and progress tracking.

Can I block apps permanently on iPhone?

Yes — SupaFocus custom sessions run from 5 minutes up to 4 weeks, and recurring schedules re-apply blocks every day automatically.

Does blocking apps on iPhone require a jailbreak?

No. SupaFocus uses Apple's official Screen Time API, so blocking is fully supported by iOS — no jailbreak, no VPN, no profiles.
