✍️ Lightning-fast daily logging
Open the app, choose a kanji that captures your day—「楽」 for joy, 「忙」 for hustle, 「眠」 for exhaustion—then close it again. That’s it. You can finish in three seconds while standing in an elevator.

🗓️ Calendar at a glance
Our home screen is a spacious monthly grid. Colors adapt to your system theme, and each square centers the kanji you chose, creating an instant visual timeline of mood swings, triumphs, and rough spots.

📝 Deep-dive notes when you need them
Tap any date to expand a rich-text editor. Write a quick sentence or pour out a thousand-word reflection—it’s up to you. Your note stays linked to the day’s kanji, so a single tap always reveals the story behind the symbol.

📊 Export & import with CSV
Own your data: back it up to cloud storage or migrate to another phone in seconds. The file is human-readable, so you can run your own analytics or view entries in Excel and Google Sheets.

🖼️ Home-screen widget (Android 14+)
Keep today’s kanji and weekday on your launcher without opening the app. The widget updates automatically at midnight (local time) and respects your color settings.

💡 Why a single character?
Minimalism lowers the barrier to entry; you’re far more likely to keep a habit that takes seconds. Over weeks, patterns emerge: you’ll see clusters of positive kanji after vacations, or a string of 「疲」 after late-night crunches. That awareness nudges better life choices.

☁️ Private by default
All data lives only on your device unless you choose to export it. No sign-up, no tracking, no intrusive analytics—just your memories.
