Your life,
in weeks
Aion is a memento mori for iPhone: it shows you how many weeks you have lived and how many, statistically, remain. This is the life of someone who is 47: tap the date and put in yours.

Each dot is a week. The filled ones don’t come back.

days lived, at 47. It slips by even when you are not watching.
One page at a time
The weeks
About 4,300 dots, one per week. The lived ones filled, the current one pulses. Tap a dot: “Week 1,204 · you were 23”.
What matters, counted
How many more times
Pick a person and how often you see them. Aion counts the occasions left, on the life expectancy of both of you.
It is the hardest count: you only see it after saying yes.
Dots that remember
Mark a past week with a title. An amber ring surrounds it, forever.
The grid stops being statistics and becomes yours.

candles lit so far
Statistically you will light ~36 more. None is promised: that is why you make a wish.
ContinueCandle day
On your birthday, in place of the opening card: how many candles you have lit and how many, statistically, you will light.
Once a year. No more.
Outside the app
Four widgets, in the shapes iOS allows. They refresh at midnight.
- Aion
- Small: the 52 weeks of the year of your age. Medium: one dot for every year. On the Lock Screen, the year strip and the week next to the date.
- Weeks lived
- On the Lock Screen, the number and nothing else.
- Event
- How many more times, for the event you choose.
- Memento
- The card of the day, on the Home Screen and the Lock Screen.
iOS draws Lock Screen widgets in a single colour; on the Home Screen they follow the theme you chose.

Aion
AionWhy Aion
The Greeks had two words for time. Chronos is the one that devours: deadlines, hours left, the clock.
Aion is the other one, whole time turning on itself. In the Sentinum mosaic he holds the ring of the zodiac, while the four seasons pass at his feet.
An app that counts weeks could have had many names. This one took the name of the time that is in no hurry, because it wants you to look at your whole life, not your next appointment.
The mosaic was the floor of a Roman villa in the Marche, at Sassoferrato, around 220 AD. Today it is in Munich, at the Glyptothek.
Letters to who you will be
Sealed on 12 November 2026.
Opens on 12 November 2031, in week 2,744.
If you are reading this, 260 weeks have passed and you lived them, not me.
Today I am forty-seven and afraid of wasting it in meetings. I hope you changed at least one thing: that you have dinner with mum more often, that the bike in the cellar still has air in its tyres.
If you changed nothing, that is fine too. But look at the grid, and count the dots between us.
You, in November 2026
The 260 weeks between the letter and you. The ring is the week it arrives.
Sample letter: yours stay unreadable, even to you, until the week you chose.
The same truth,

Today’s card
Friday 13 November
They prepare for life instead of living it. — Seneca
It is the same card that opens the app today, on the widget and in the morning notification. Eighty cards about last times, twenty from Seneca’s On the Shortness of Life, one a day, never at random. Under every card you can write a thought: it stays in a notebook, yours only.
One price, once
A memento mori, in the seventeenth century, was a painting hung in the study. This one fits in your pocket and asks for nothing else: you are not the product.
