About Kyokun — Learn from Mistakes
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.
