Dueday: Deadline Countdown

Dueday is a simple, focused deadline countdown app. Add the dates that matter and see exactly how many days are left — at a glance, on your home screen, and right when you need a reminder.

WHY DUEDAY
Deadlines pile up: project due dates, exams, submissions, bills, trips, anniversaries. Dueday keeps them all in one place and counts down the days so nothing sneaks up on you.

BIG, CLEAR COUNTDOWN
Every deadline shows the days remaining as a bold D-day count (D-7, D-DAY, D+3). Your list is automatically sorted by the nearest due date, so the most urgent item is always on top.

HOME SCREEN WIDGET
Add the Dueday widget to your home screen and always see the days left for your next deadline — no need to open the app. The countdown updates every day on its own.

REMINDERS
Get a local notification before each deadline. Choose on the day, 1 day, 3 days, or 1 week before — per deadline.

ORGANIZE YOUR WAY
- Color-code each deadline
- Add an optional note
- Edit or delete any time
