"Remember that you too must die." This ancient Roman phrase, "Memento Mori," is not about fearing death — it is a philosophy for living each moment to the fullest. This app makes the time you have left quietly, precisely visible — in days, and in how many more times. REMAINING TIME - Real-time countdown of your remaining days and hours, with your life progress - Full-screen countdown - Week Grid: your whole life, one square per week (swipe the main screen) TIMES LEFT - Full Moon: how many more times will you watch it rise - Count up to five things that matter — seeing your parents, 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 - Tap a count to see exactly how it's calculated ALSO - 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 - My Reminders: set your own personal notifications - Japanese and English support LIFE EXPECTANCY DATA Reference values are based on the average remaining life expectancy for your current age, from Japan's 2025 Abridged Life Tables (Ministry of Health, Labour and Welfare). You can also set your own date freely, and recalculate anytime by opening Final Day in Settings. PRIVACY All data is stored locally on your device. Nothing is ever sent to external servers. No account, no ads. To remember death is not despair. It is a discipline for truly living today.
