## What is PreFace?

Stop the scroll. Start your story.

Most app blockers just shut you out. "Preface: Screen Time Control" invites you back to your focus. By turning a simple iOS Automation into a powerful mindfulness tool, Preface intercepts your digital distractions and replaces them with a curated moment of wisdom.

The "Preface" Experience:

Instead of a cold "Blocked" notification, Preface provides a transition. It’s a pause, a moment of reflection that reminds you why you put the phone down, featuring a minimalist design and handpicked quotes from history’s greatest thinkers.

How it Works (Simple 1-Minute Setup):

Preface utilizes the power of iOS Shortcuts & Automations to give you full control over your focus.

Choose Your Distractions: Identify the apps that pull you away from your goals.

Set the Automation: Use our simple, step-by-step guide to link your target apps to Preface via the Shortcuts app.

The Redirection: Every time you instinctively tap a distracting app, Preface will automatically open first, presenting you with a beautiful quote and a chance to breathe.

Key Features:

Intentional Friction: We replace a mindless habit (scrolling) with a conscious choice (reflecting).

Privacy First: Because you use native iOS Automations, Preface never needs to track your "Screen Time" data or monitor your browsing history.

Curated Wisdom: A library of deep, inspiring quotes to help you reset your mindset in seconds.

Minimalist Aesthetics: A clean, distraction-free interface that respects your mental space.
