Hardcore Focus is an iPhone app blocker with an on-device AI Gatekeeper: when you try to unlock a blocked app early, you argue your case to Apple Intelligence on the phone. Weak excuses are denied. A yes is a timed exception, not an open door.

What is the AI Gatekeeper?

It is a bypass mode, not a chatbot bolted onto a dashboard. The other modes are No Bypass (locked is locked) and a 15-minute bypass. Gatekeeper sits between them: you can ask, but you have to win.

The model is Apple’s on-device FoundationModels. Inference runs in the main app, not in the Screen Time extension, and nothing is sent to a Hardcore Focus server. There is no account.

How a grant works

  1. You hit a blocked app. Shield offers “Make your case.”
  2. You return to Hardcore Focus and state why.
  3. The Gatekeeper decides yes or no, and if yes, for how many minutes.
  4. Ceiling: 15 minutes on a single grant. Repeat grants the same day shrink the ceiling; a daily cap is an automatic deny.

That cap is enforced in code, not just in the prompt.

What if I don’t have Apple Intelligence?

If Apple Intelligence is unavailable or off, Gatekeeper is hidden and the mode degrades to the fixed 15-minute bypass. The blocker still works. You just lose the argument layer.

Can I still cheat?

Yes. The universal iPhone hatch is Settings → Screen Time → turn the app’s access off. No Screen Time blocker, including this one, can stop a determined you from revoking the permission or deleting the app. Gatekeeper is for the “I’ll just unlock it for a second” reflex — the one you already lose to yourself.

Can you bypass iPhone app blockers? is the honest version of that.

How this is different from Opal / Jomo / Brick

  • Opal — Deep Focus is a paid strict mode, not an on-device argument.
  • Jomo — Strict Mode can block Settings edits. Different tradeoff; no AI negotiation.
  • Brick — Physical NFC tag. Stricter if you leave the tag at home. No software argument.

Hardcore Focus vs each: vs Opal, vs Jomo, vs Brick.

Pricing

Gatekeeper is not an add-on. The app is a hard paywall: $3.99/week, $8.99/month, or $49.99/year (7-day trial on annual). Download on the App Store.
