System-level block
Uses Apple's Screen Time APIs. Not a timer you can swipe away.
Stay locked. Stay focused.
Focus, without a subscription.
Real system-level blocking, physical unlock, data only on your iPhone. Free forever, no ads, no account.
Coming to the App Store How it works
Free forever
No subscriptions, no gimmick free tier.
No ads
No banners, no trackers, no upsell.
No account
Open and use. We never ask for an email.
100% on-device
Data stays on your iPhone. There is no server.
What it does
Serious when it matters, never punitive.
Friction, Hard, NFC
A breath, a hard lock, or a physical unlock with an NFC tag or QR.
Focus profiles
Work, Study, Evening, Social Detox. One button: Lock Now.
Strict Mode
Makes it harder to uninstall or revoke permissions mid-session.
