Your blocking choices, activity log and weekly recap stay on your iPhone. Open Book never sees your browsing and doesn't share your activity with anyone.

Native blocking. No VPN.

Open Book uses Apple's Screen Time framework, not a VPN or traffic inspection. When blocking is on, Safari's adult-content filter turns on automatically. Use Apple's own picker to choose apps, app categories and websites to block. What blocking without a VPN means.

Keep the apps you need

Blocking a whole category? Add app exceptions so a work chat app or another app you rely on keeps working.

Short pauses on your terms

Need a break? Pause blocking for 15, 30 or 60 minutes. Blocking is scheduled to resume when the pause ends, and you can resume it sooner. iOS may delay the resume while your phone is idle.

Your activity, privately

The Activity tab lists when blocking started or stopped and when pauses began and ended. Filter it by type. It records event types and times only, never websites, app names or browsing history.

Weekly recap

Turn on the weekly recap from Activity to get a short notification each Sunday evening. It counts your pauses for the week and the days you had none. The recap is built on your iPhone from your Activity log.

You're in control

Stop blocking whenever you want, after a 30-second wait, unless you have started a Strict mode lock. You can also turn off Screen Time access in iPhone Settings at any time. Open Book is for adults managing their own iPhone. It is not a parental-monitoring tool, and no blocker you control yourself is bypass-proof. Blocking unwanted adult content on iPhone.

Prefer Apple's own controls first?

Start there. Apple's built-in Screen Time content restrictions can limit adult websites without installing anything, and our Safari guide walks through them step by step. Open Book adds guided setup, app and category blocking, app exceptions, short pauses and a private activity log.
