Keep important days close.

Track birthdays, anniversaries, love days, baby milestones, work days, exams, payments, and travel plans. No account, no server, and daily records stay on your device by default.

Quiet, clear, reliable.

Countdown Days is not a social product or a cloud service. It focuses on organizing the dates you care about and presenting them clearly.

Countdown & count-up

Count down to future plans, or count up from relationships, habits, and life milestones.

Gregorian & lunar

Track birthdays, traditional festivals, and repeating anniversaries with flexible calendar options.

Widgets

Home Screen and Lock Screen widgets give you a quick glance while private records stay hidden.

Memory notes

Add notes, moods, and photos so each day can carry more than a number.

Local reminders

System local notifications help with birthdays, exams, payments, and plans.

Backup & restore

Full and encrypted backups make device migration and long-term preservation easier.

Offline by default.

Days, memories, photos, and settings are stored locally by default. Core features do not require an account or server.

Built for long-term records.

Categories, pinned days, private space, posters, widgets, and backups are designed around personal records that last.
