nfcGuard

Physical Friction for Digital Wellbeing

Block distracting apps with NFC tags as physical keys. Place a tag somewhere inconvenient — your kitchen, gym bag, a friend's house — and think twice before mindlessly scrolling.

YOUR WILLPOWER
ISN'T ENOUGH

The average person unlocks their phone 150+ times a day. App blockers that use timers, PIN codes, or "are you sure?" prompts fail because the override is always one tap away. nfcGuard is different.

nfcGuard's Approach
Physical friction changes the equation.

When unlocking requires walking to another room to tap an NFC tag, the cost of giving in becomes real. You don't need more willpower — you need a better system.

The result
INTENTIONAL USAGE
FOUR STEPS
TO FOCUS
01

Create Modes

Choose apps to block — or allow only essential ones. Create different modes for work, sleep, study, or any context.

02

Link NFC Tags

Register physical NFC tags as unlock keys. Place them in inconvenient locations — your kitchen, gym, or a friend's house.

03

Set Schedules

Automate blocking with per-day schedules. Different times for weekdays vs weekends. Set it and forget it.

04

Stay Focused

Blocked apps show a full-screen overlay. To unlock, physically walk to your NFC tag and tap. Friction is the feature.

BUILT TO
BE UNBEATABLE

Every feature is designed around one principle: make it physically harder to give in to distraction.

Block Mode

Block specific distracting apps while everything else stays accessible. Target Instagram, TikTok, YouTube — whatever your weaknesses.

Allow Mode

Nuclear option. Block everything except a whitelist of essential apps. Only phone, messages, and maps? Done.

NFC Tag Lock

Each mode can require a specific NFC tag to unlock. Wrong tag? Denied. No tag linked? Any NFC device works.

Smart Schedules

Per-day configuration with different start and end times. Auto-activate for work hours, auto-release when you're done.

Persistent Service

Survives reboots, task kills, and app restarts. nfcGuard comes back every time. No escape routes.

Emergency Reset

Lost your tag? A 60-second cooldown + confirmation text safety flow lets you recover without losing your configurations.
