Hardcore Focus is an iPhone app blocker that uses Apple’s native Screen Time (Family Controls) API — the same framework parental controls use. It does not install a VPN, does not proxy your traffic, and does not require a Hardcore Focus account.
How does Shield block apps?
You pick apps or categories. Shield can run:
- During a focus session — on when the timer is running
- On a schedule — work hours, evenings, weekends
- Always on — until you change the rule
If you open a blocked app, iOS shows the Shield screen instead of the app. That screen is configured by Hardcore Focus (including the Gatekeeper “make your case” path). Apple caps a Screen Time blocker at 100 apps at once.
Screen Time vs a VPN blocker
Most iPhone blockers (Hardcore Focus, Opal, Jomo, ScreenZen, Brick’s software layer) ride on Family Controls. Freedom is the common exception: an on-device local VPN filter, useful if you also need a laptop.
Native Screen Time blocking never routes traffic through someone else’s servers. That is the privacy reason to prefer it if you only need iPhone.

Bypass modes
Because you granted the permission, Settings → Screen Time can still turn it off. Inside the app, Hardcore Focus gives you three unlock styles:
| Mode | What happens if you try to open a blocked app |
|---|---|
| No Bypass | Locked is locked for the session |
| 15-minute bypass | One short, deliberate exception |
| AI Gatekeeper | You argue your case to on-device Apple Intelligence. Grants cap at 15 minutes. If Apple Intelligence is off, this mode degrades to the 15-minute bypass. |

What it is not
- Not a parental-control dashboard. There is no remote parent view and no account.
- Not a Mac or Android app. iPhone + Apple Watch; iPad runs the iPhone app.
- Not a free tier. A subscription unlocks the full app ($3.99/wk, $8.99/mo, $49.99/yr with a 7-day annual trial).
