What if you knew exactly how many days you have left to live? DIEM calculates your life expectancy from your profile and shows you, in real numbers, the time already lived and the time remaining. Not to cause anxiety. To stop letting days go by without noticing them. Every morning, a quote from the great Stoic philosophers โ Seneca, Marcus Aurelius, Epictetus. To start the day with intention. Every week, a visualization of your year to stay grounded in the present. What DIEM does โ Calculates your remaining days from your date of birth, your country and your lifestyle โ Displays a different Stoic quote every morning โ Visualizes your year week by week โ Keeps a history of your favorite quotes โ Stores all your data locally, on your iPhone only Why DIEM? Carpe diem doesn't mean "enjoy every moment." It means: seize the day before it's too late. DIEM is here to remind you. Every morning, quietly.
