About this app

If life were 24 hours, what time are you living right now?

One Day Life compresses your entire life into a single day — a gentle,
well-living diary that helps you feel the weight and warmth of your time.
A life clock, an emotional journal, home widgets, and a lock screen
reminder — all in one app.

If you're 25, it's about 7:30 in the morning of your life.
At 40, you've just passed noon.
The life clock turns your birth date and life expectancy into the
time of day you're living right now.

This isn't a cold countdown app.
It's a warm reminder: "So much precious time still remains —
let's keep one photo of today's sunset in our diary."

✦ Life Clock
A star-dusted clock maps 24 hours onto your whole life.
The hour hand, minute hand, and a lavender second hand show this very moment.
See the exact years you've lived, down to 8 decimal places.

✦ Time lived · Chances left
The seasons, weekends, and meals you've already passed through.
And the times you may still see your parents, or watch the cherry blossoms.
Let the numbers bring the value of everyday life back into focus.

✦ Emotional journal by value
Family trips, love, achievement, the everyday…
Create categories that match what you cherish,
and leave a single photo and emotion tag — a diary entry in one line.

✦ A year of grass
365 days as a field of dots. Like a GitHub contribution graph,
see the flow of a whole year at a glance, and track how each year changes.

✦ Yearly goals (chances)
Write small goals like "eat out with family 12 times this year,"
and fill them in, one at a time.

✦ Home widget · Lock screen
Every time you wake your phone, every time you glance at the lock screen,
it quietly reminds you that your life clock keeps flowing.
Choose from small, medium, and large widget clocks for your home screen.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✦ Dark-first design
Made for the quiet hours when you look back on your day in bed,
with a deep, star-dusted dark tone — a dark-mode-first diary.
Light mode is supported with equal care.

✦ Everything stays on your phone
No server. No sign-up.
All your data lives only on your device.
Back it up as a .zip file whenever you want.
