Description by Jincoa (from Google Play)
Exams, discharge dates, anniversaries, trips, deadlines — Simple D-Day keeps every important date in one place.

📅 Three calculation modes
- D-day: Days remaining until a target date (D-30, D-Day itself)
- D+day: Days elapsed since a start date (day 365 together, etc.)
- Yearly repeat: Automatically recalculates the D-value for recurring dates like birthdays and anniversaries

🗂️ Clean card list
Events are sorted by closest date so you see what matters most the moment you open the app.

🎨 Color tags per event
Tell exams, anniversaries, and deadlines apart at a glance with color-coded cards.

🔒 Privacy-friendly
No sign-up or login required. Your events are stored only on your device.

🌏 Korean / English support
