Everything you need to know about Yeoun.
Yeoun is a private daily journal and mood tracker for iOS. The name comes from the Korean word 여운 (yeo-un), meaning the lingering feeling after a meaningful experience. Write about your day, track your mood, and discover the patterns that shape your life.
Anyone who wants to build a journaling habit and better understand their emotional patterns. Whether you're new to journaling or have been writing for years, Yeoun meets you where you are with prompt packs, mood tracking, and a companion plant that grows alongside your streak.
Yes. The full journaling experience is free: unlimited entries, mood and focus tracking, your growing companion plant, prompt packs, photo attachments, daily reminders, PDF export, and all color themes. No ads, no data selling, no paywall on the basics.

When you start journaling, you get a small sprout called a hwachyo (화초). It grows each day you write an entry, progressing from a seedling through several stages until it reaches full bloom. It's a quiet, visual reminder of your consistency.
Yeoun's AI features are powered by Anthropic (Claude) and are entirely optional. They include mood analytics, automatic event detection from your entries, and weekly pattern insights. AI features require your explicit consent before they're activated, and your data is never used to train AI models.
Yes. Your journal entries are stored locally on your device and never leave your phone unless you opt into AI features. Even then, data is processed transiently and never stored on our servers. We don't collect location data, contacts, or advertising data, and we don't sell your information.
Yeoun is currently available for iPhone (iOS). We're focused on making the iOS experience great before expanding to other platforms.
