Cortex helps you take back control of your screen time with one simple gesture: a tap of an NFC card, a QR code scan, or a manual start.
No account. No tracking. No cloud. Everything stays on your iPhone.
— FOCUS WHEN YOU DECIDE —
Create a mode for each moment of your day: work, study, meals, sleep, family time. Pick which apps to block. Pick how the session starts and ends.
— STRATEGIES YOU PICK —
• Manual: start and stop from inside the app
• NFC card: tap your Cortex card to start or stop
• QR code: scan a QR to open or close a session
• Time range: automatic focus between two times (e.g., 10pm → 7am)
• Timer: fixed duration with optional NFC early unlock
• Mix: combine strategies (NFC + manual, QR + timer…)
— INSTANT BLOCKING —
Cortex uses iOS Family Controls (Screen Time API) to block the apps and websites you choose, the moment your session starts. Open a blocked app, and you'll see a custom Cortex shield instead.
— DYNAMIC ISLAND TIMER —
Your session timer shows live on your Lock Screen and in the Dynamic Island.
— BREAKS AND EMERGENCIES —
Need a 5 to 15 minute breather? Pause mode lets you through temporarily, then re-blocks automatically. Emergency unlock gives you 3 uses per rolling 4-week window.
— PARENTAL PIN —
PIN stored only in iOS encrypted Keychain. No backup on our servers.
— PHYSICAL NFC CARD —
The Cortex card (sold separately on liberetoncortex.com) turns your focus ritual into a tangible gesture.
— TOTAL PRIVACY —
