About this app
"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. FEATURES - Real-time countdown of your remaining days and hours - Life progress bar - Full-screen countdown - Week Grid: see your whole life at a glance - Year Progress: how much of this year has passed - Full Moon: how many more times will you watch it rise - Home Screen and Lock Screen widgets - Daily reminder 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 2024 Abridged Life Tables (Ministry of Health, Labour and Welfare). You can also set your own date freely. PRIVACY All data is stored locally on your device. Nothing is ever sent to external servers. To remember death is not despair. It is a discipline for truly living today.
