Tap your phone. Lock in.

BuckBlock turns a physical NFC tag into a focus switch. Tap it, pick a duration, and the apps that steal your attention disappear until the timer runs out — or you tap the tag again.

What it does

Focus you can feel in your hand

BuckBlock pairs an iOS app with a physical NFC tag — the "BuckBlock Station." No willpower battles with your settings screen. Just tap and go.

NFC

Tap to lock

Hold your phone to the BuckBlock Station. Pick a duration — 15 minutes to indefinite — and your distracting apps are shielded by Apple's Screen Time.

Always-blocked essentials

Social media and games are locked down by default. Music, messages, and utility apps stay toggleable so you can still get class notes through.

Tap again to unlock

Indefinite sessions end the moment you tap the tag again. Timed sessions release themselves. No early-unlock loopholes hiding in a menu.

How it works

Four steps from distracted to done

STEP 01
📲

Tap the NFC chip

Hold your phone to the BuckBlock Station on your desk, backpack, or dorm wall.

STEP 02
⏱️

Pick a duration

Choose 15m, 30m, an hour, two hours, a custom time — or indefinite.

STEP 03
🔒

Apps get blocked

Screen Time shields your selected apps. Notifications for those apps go quiet too.

STEP 04

Scan again to unlock

Timer ends on its own, or tap the tag a second time to break an indefinite session.
