A memento mori app, not just a poster
A memento mori poster shows your life as a grid of weeks and reminds you, once, that time is finite. A memento mori app keeps that count live and connects it to today: you still see your life in weeks, but then you grade each hour green, amber or red. Your Hours Are Numbered is built for people who want the practice, not just the print — and it's free.
What a poster does well
A well-made memento mori poster or phone wallpaper is a genuinely good object. It renders roughly 4,000 weeks, you shade the ones you've lived, and every time you glance at it you feel the weight of the remaining squares. As a one-line reminder, it works.
Where a poster stops
- It never updates. The week that just passed is still blank until you remember to fill it in by hand.
- It asks nothing of you. A print can't connect “my life is finite” to “so how did I spend this hour?”
- It fades into the wall. Any fixed image stops being seen after a week or two.
What the app adds
Your Hours Are Numbered keeps the wide lens — your whole life in weeks — and adds the narrow one. After each block you write one honest sentence and mark it a color, so the finitude you feel from the grid attaches to a concrete hour you just lived. The weeks are made of hours; the app is the only memento mori that keeps both in view.
It runs in the browser, needs no account, and stores everything on your device. If you love the poster, keep it on the wall — then use the app to actually spend the weeks it reminds you of.
FAQ
Is there a memento mori app instead of a poster?
Yes. Your Hours Are Numbered is a memento mori app: it draws your life in weeks like a poster does, but it's interactive and free, and it connects that whole-life view to a daily habit — you grade each hour green, amber or red. A poster reminds you once; the app turns the reminder into a practice.
What's wrong with a memento mori poster or wallpaper?
Nothing — they're beautiful and they work as a glance. The limit is that a static print or lock-screen image never changes and never asks anything of you. After a week it fades into the wall. An app keeps the count current and links it to what you actually do today.
Is the memento mori app free?
Yes. The life-in-weeks view is free with no signup, and hour grading is free too. Premium only adds cloud sync, full history and export.
