## What is PrincipleX?

Saved a great quote, then forgotten it when you needed it?

PrincipleX helps you save personal principles, reading highlights and lessons from life. Organize them, revisit them with daily reminders and add your own reflections, so useful ideas become more than a collection.

KEEP IDEAS WORTH REMEMBERING
Capture a meaningful quote, a lesson from experience or a principle you want to live by. Add details and a source to preserve the context.

BUILD YOUR OWN PRINCIPLE LIBRARY
Organize ideas with folders and tags. Give thoughts about work, life and reading a place of their own.

RETURN TO WHAT MATTERS
Set daily reminders to revisit saved principles. You can also keep one principle fixed while you focus on putting it into practice.

MAKE ROOM FOR REFLECTION
Add your thoughts to each principle: When does it apply? Did you follow it? What could you choose next time? Turn collected ideas into personal understanding.

ACCESS PRINCIPLES WITH SIRI
On supported systems running iOS 27 or later, allow access to find, read and open saved principles with Siri, or use them in Shortcuts. You decide separately whether to include your reflections.

DISCOVER AND SHARE
Explore thoughtful ideas and save principles that resonate. Turn a principle into an image to share with friends.

With iCloud sync, continue organizing and revisiting your principles across your own devices.

Start with one principle you truly want to remember.

Siri availability depends on your device, language, region and system settings.
