How many times
are left?
The app counts times, not days. Dinner with Mom, a family trip, the summers with your child. Seeing how many are left changes how today's one feels.
This isn't a life expectancy prediction. It's simply a way to visualize time.

LIFE CALENDAR
One square,
one week of your life.
The weeks you have lived are filled in; the weeks ahead stay empty. You can see at a glance where this week sits — and open any square to write down what mattered.

- Weeks ahead
- This week
WHAT IT COUNTS
It counts times, not hours.
No schedules, no tasks — just how many are left.
Days, summers, weekends
From your birthday and the life horizon you choose (80, 90, or 100), the app counts the days still ahead, and the summers, springs, and weekends that come with them.
Remaining opportunities
Dinner with Mom, a family trip. Add something that comes round on a rhythm, and see about how many are left if that rhythm continues.
Summers with your child
Add your child's age, and the app counts the summers you have together before they turn 18.
Today
Choose one thing that matters today, and note what you would like to remember. It is not a to-do list.
Weekly reflection
On Sunday, a few words about what mattered this week. They stay on that week of your life calendar.
Widgets
Days remaining and summers left on your Home Screen — no need to open the app.
Who it's for
- Years seem to go by faster than they used to
- You want to stay aware of the time you have with your children
- You would rather remember what matters than what is due
- You think in occasions, not deadlines

- Does it predict how long I will live?
- No. You choose the life horizon yourself (80, 90, or 100). The numbers count how many times fit between today and that horizon on a real calendar — they are not a prediction. It is simply a way to visualize time.
- How is “about how many” calculated?
- Days, summers, weekends, and weeks are counted on the real calendar. Only the opportunities you add are estimates — they assume the rhythm you set continues, so they are always shown with a “~”.
- Where is my data stored?
- Your birthday, the things you count, and the notes you write are stored on your device. See the privacy policy for details. You can export everything as JSON at any time.
- Will it send me notifications?
- One to three quiet notices a week. Never a reminder to do something — just a note about how many are left. You can turn them off.
- How much does it cost?
- Everything available today is free. Some features will later be offered as Once Counts Plus.
- Is there an Android version?
- Right now, Once Counts is being prepared for iPhone (iOS) only.
