DayStone - Countdown Tracker
Birthdays, Goals & Milestones
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Count down to the days that matter with a clock that ticks to the second, count up your streaks with milestone reminders, and add free widgets in every size.
How many days until the days that matter?
DayStone counts the days until birthdays, anniversaries, trips, exams and every date you care about. It also counts up: track how many days since you quit smoking, started a habit or met someone special.
▼ Your next big day, front and center
The closest event sits at the top of the home screen in large type. Everything else is grouped into Upcoming, Counting up and Past events.
▼ A countdown that ticks to the second
The detail screen shows the day count in large numbers and a live clock such as "In 11:20:35: 44 days left", showing exactly when the count changes next. For dates a month or more away you also see the period, like "1 month 14 days".
▼ Count-ups and milestones
Track the days since quitting smoking, starting the gym or your first date. DayStone notifies you at milestones: 7, 30 and 100 days, every 100 days after that, and every anniversary.
▼ Celebrate the day itself
On the big day you see "Today", and you can share the card with its photo as an image.
▼ Ready in seconds
Enter a title and a date. For a past date, choose how to count: days since that date, or until the next yearly or monthly anniversary. Birthdays and anniversaries repeat every year automatically.
▼ Make every card your own
Use a photo or one of 12 colors as the background, pick an icon, and organize events into six categories: Birthday, Travel, Exam, Anniversary, Work and Other.
▼ Never forget
Get a reminder on the day and an advance reminder from 1 to 365 days before, at the time you choose.
▼ Home screen widgets
Small, medium and large widgets; the large one also shows this month's calendar. Every widget size is free.
▼ Five color themes and dark mode
Gem, Stone, Moss, Night and Sakura, with light, dark and system appearance.
▼ Free and Premium
Free: up to 5 events and 5 photo backgrounds, with the Gem and Stone themes. The only ad is a banner at the bottom of the home screen.
