About the App
Memento Mori — remember that you will die.
The Stoic philosophers of ancient Rome taught a simple discipline: never forget that you are mortal.
This app makes the time you have left quietly, precisely visible.
Your remaining days, the weeks of your life laid out as a single grid, the full moons still ahead — and how many more times you will see your parents, or the cherry blossoms. Each is a quiet reminder that time is finite.
Key Features
- Real-time countdown of remaining days and hours, with your life progress
- Full-screen countdown
- Week Grid — your whole life, one square per week
- Full Moon — how many more times will you watch it rise
- Times Left — count up to five things that matter, like seeing your parents or the cherry blossoms. With another person, their remaining life expectancy is estimated from their age or birthday, and the count ends at your final day or theirs, whichever comes first
- Transparent math — tap a count to see exactly how it's calculated
- Share cards — long-press any screen to share it as an image
- Home Screen and Lock Screen widgets (remaining days, Week Grid, Full Moon, Year Progress)
- Daily reminder, with an option to vary the time each day, and full moon night notifications
