Focus Firewall
Support & documentation
No account, no server, no analytics. Every rule, session and number lives on the iPhone that produced it.
Open Settings › Protection check. It tests every layer end to end — permission, the shield, the schedule monitor and the App Group — and reports which one failed, rather than leaving you guessing.
Yes. The owner of an iPhone can revoke Screen Time access in iOS Settings, and no app can prevent that. Strict Mode makes a rule harder to change while it is running, but it is friction, not a lock. When access is withdrawn, Focus Firewall tells you protection has stopped instead of pretending it is still on.
iOS delivers timing callbacks when the device is in use rather than on a strict clock, so ends are accurate to about a minute. There is no API that ejects you from an app you already have open.
Apple's scheduling system refuses windows shorter than fifteen minutes. Shorter blocks are ended by a notification and by the shield's own self-healing instead.
This is deliberate. Apple's app-selection tokens are not guaranteed to resolve on another device or after reinstalling, so a backup keeps your rules' times and settings and asks you to re-pick the apps. Carrying the tokens over would produce rules that look configured and silently block nothing.
