Latest Letter

“To my daughter, when you turn 18…”

Everything you need
to live intentionally.

Countdown That Matters

Your remaining days, calculated in real time from WHO actuarial tables adjusted for your country and sex. Not a scare tactic — a compass.

Daily Reflections

One guided prompt each evening. Build the habit of asking what mattered — and what you will do with tomorrow.

Letters to Loved Ones

Write letters to be delivered when it counts — a birthday, a milestone, or after you are gone. Leave something real in ink and parchment.

Family Awareness

Add the people who matter most and see their countdowns alongside yours. Understand the finite nature of shared time.

Home Screen Widget

Your countdown always visible — lock screen, home screen, or both. A daily reminder that sits quietly with you through the day.

Streak Tracking

Visual streak tracking builds the reflection habit. Each consecutive day compounds your clarity and commitment to living intentionally.

Three steps.
A lifetime of clarity.

“It is not that we have a short time to live, but that we waste a great deal of it.”

— Seneca, On the Shortness of Life

Write what matters.
While you still can.

The Letters screen lets you compose messages to the people you love — stored locally in a private parchment-and-ink interface. Delivered at a milestone, a birthday, or when the time comes.
