⚠ EMERGENCY (3)

One tap to lock

The lock button is the whole interface. Tap your tag and every distracting app goes dark — no menus, no settings maze.

Proof you're winning

Time saved and blocked attempts, tracked on-device. Watch the attempts counter climb while you stay focused.

Spaces for every mode

Study, work, sleep — separate blocking profiles you can switch instantly. One tag, many rules.

// How it works

Three taps.
Zero willpower.

Choose your apps

Select what to block — social media, games, news. Whatever steals your focus.

Tap your NFC tag

Any NFC sticker, card, or keychain. Place it on your desk, wallet — wherever works.

Done. Locked.

Try opening a blocked app — BLOK intercepts it. Tap NFC again to unlock when ready.

Progress tracking

Daily streaks, blocked attempts, time saved.

SAFETY

Emergency unlock

Limited emergency unlocks for genuine urgency. Enough to feel safe.

SMART

Notification blocking

Block notifications too. No tempting banners pulling you back.

DESIGN

Dark & minimal

A brutalist interface built with purpose, not decoration. Gets out of your way.

The average person picks up their phone 96 times a day.
BLOK makes every single one intentional.

// Trust

Open source.

This matters: an app that can lock your phone should never be a black box. Every line of BLOK's code is public and auditable — you can read exactly what it does, and verify that nothing leaves your device. No hidden tracking, no secrets.

// Freedom

Any NFC tag.

BLOK writes to any standard NFC tag — stickers, cards, keychains, wristbands. Grab one for cents, record it from the app in seconds, and it becomes your physical key. No proprietary hardware, ever.

// FAQ

Questions.

Any standard NFC tag — NTAG213, NTAG215, NTAG216. Stickers, cards, keychains, wristbands. Less than $1 each.

You get limited emergency unlocks for genuine urgency. But friction is the point — the tag is your commitment device.

No. BLOK is 100% offline. No accounts, no cloud, no data collection. Everything lives on your device.
