Days Mark: Countdown & Since
Lunar Birthday, Anniversary
Free · In‑App Purchases
Free for 90 days, then one payment. No subscription, no account, no ads — your days sync privately through your own iCloud.
Days Mark counts the days that matter — down to the ones still coming, and up
from the ones already past. Birthdays, anniversaries, the day you met, the day
you quit: one list, one number each. No ads, no subscription — 90 days free,
then one purchase.
LUNAR BIRTHDAYS, CONVERTED EVERY YEAR
Record a date on the Chinese lunar calendar and Days Mark works out this year's
Gregorian date for you, leap months included. For parents' and grandparents'
lunar birthdays, you never have to work out the date by hand again. Lunar dates
read naturally in English — or in traditional gan-zhi form, with one setting.
DAYS UNTIL AND DAYS SINCE
Yearly dates count down to the next time. One-time dates count up from the day
they happened. Whichever falls on today is lifted to the top.
ONE DOT, ONE DAY
Every day of the current cycle is a dot. Milestones mark the next round
hundred, plus 100, 1,000 and 10,000 days. Anniversaries are numbered from the
first year you recorded.
ON YOUR HOME SCREEN AND LOCK SCREEN
Widgets for one day or your next few, in every size. Set the one-day widget
to count up, and an anniversary with its first year recorded shows the days
since that first time. Ask Siri how many days
are left. Find any day in Spotlight with its count.
QUIET REMINDERS
A notification on the day, and as many days early as you want. Nothing else.
YOURS ALONE
No account, no sign-up, no ads, no analytics. Your days sync between iPhone,
iPad and Mac through your own private iCloud. We have no server and cannot see
what you record. There is no account to lose.
FREE FOR 90 DAYS, THEN ONE PAYMENT
Use everything free for three months. After that, the days you've added stay
visible and keep reminding you — adding or editing more is a single one-time
purchase. It is not a subscription.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
The one-day widget can now count up. Choose Count up when you edit the widget, and an anniversary with its first year recorded shows the days since that first time. Days without a first year keep counting down.
