## What is Kyokun?

Kyokun is a private reflection app for turning mistakes, regrets, and small insights into practical lessons.

You do not need to write a long diary every day. Start with one line when something catches your attention, then come back later to organize what happened, why it happened, and what you will do next.

■ See repeated mistakes clearly

A lesson is not finished after you write it once. When the same thing happens again, add +1 to that lesson. The count makes it clear which patterns still need attention.

■ Reflect with three simple questions

• What happened?
• Why did it happen?
• What will you do next?

You can save only a title first, then add details whenever you are ready.

■ Remember what matters

• Pin important lessons to the top
• Search and filter past reflections
• Add photos and voice notes for context
• Sync with iCloud across your devices
• Use widgets to keep a lesson on your Home Screen

■ Built for privacy

Your lessons are personal. They are stored on your device and in your iCloud account. The content of your lessons is not sent to the developer's server.

■ Optional ad removal

Kyokun is free to start. If you prefer a quieter experience, you can remove ads with a one-time purchase.
