Physical app blocking for iPhone

Tap your Key.Lock your apps.

Deefoc turns focus into a physical action. Tap your iPhone to a Deefoc Key to block distracting apps, then tap the same Key again to unlock.

Why physical works

Most phone limits fail because they stay on the phone.

Deefoc adds a small physical step between an impulse and an unlock. The point is not punishment; it is friction you can feel.

Screen Time

Easy to override

When the escape hatch is on the same screen, it is easy to tap through in a tired moment.

Delete apps

Easy to reinstall

Deleting an app can help for a while, but it does not create a repeatable focus ritual.

Grayscale

Too easy to ignore

A visual nudge can fade into the background when the habit is already strong.

Deefoc Key

Physical unlock

Starting and ending focus requires the same Deefoc NFC Key, making the boundary tangible.

How it works

A simple ritual that makes digital boundaries feel real.

Deefoc keeps the experience focused: choose what to block, link a physical Key, then use the same Key to start and end a session.

1

Choose distractions

Select distracting apps using Apple Screen Time controls.

2

Tap a Deefoc Key

Scan a linked NFC Key to start Deep Work, Sleep, Study, or Family Time.

3

Unlock with the same Key

The Key that started a session is the Key required to end it. Wrong Key stays locked.

Built for real moments

Use a different focus mode for the parts of life that matter.

Deefoc comes with focused modes for work, sleep, study, and family time.

D

Deep Work

Block social, short videos, games, and shopping while you work.

S

Sleep

Stop late-night scrolling and keep entertainment out of bedtime.

B

Study

Keep games, short videos, and social distractions away from study blocks.

F

Family Time

Reduce work and social noise when you want to be present at home.

The iPhone app

Modes, keys, sessions, and stats in one clean flow.

The app focuses on the core loop instead of adding account setup, subscriptions, or admin controls between you and a focus session.

4

Built-in focus modes

Deep Work, Sleep, Study, and Family Time are ready on first launch.

N

NFC start and unlock

Read a Deefoc Key in the foreground, or open the app by tapping a Deefoc NFC Key.

Local focus stats

Track today, this week, streaks, and recent completed focus sessions.

Designed for the sensitive part of your phone.

Deefoc uses Apple's Screen Time APIs and keeps focus setup local-first. It does not need to read the full list of apps on a device.

User-selected blocking

The app only works with apps selected by the user through Apple's Screen Time picker.

No background heartbeat

Usage metrics should be handled with explicit, minimal foreground analytics rather than a battery-draining background monitor.

No account required

Focus modes, keys, and sessions can work without creating a user account.

FAQ

Common questions before you tap the Key.

Does Deefoc need a separate NFC reader?

No. Deefoc uses the NFC reader built into supported iPhones. You only need a Deefoc NFC Key.

Can I lock apps without opening the app?

iOS does not allow silent background app locking from a tag scan. A Deefoc NFC Key can open Deefoc, and the app runs the lock or unlock flow from there.

Why does the same Key unlock?

The same-Key rule makes the boundary harder to bypass. The Key that starts a focus session is the Key required to end it.

Does Deefoc read every app on my phone?

No. You choose the apps to block through Apple's Screen Time picker. Deefoc works with the selections you make.

Do I need an account?

No account is required for the core focus flow. Modes, keys, and sessions can work locally on your iPhone.
