Onemorrow
One line, one card, a letter
Only for iPhone
Free · In‑App Purchases
iPhone
Before bed, write one line about how tonight feels.
That's all. A little star child delivers your "night card" — a two-minute wind-down ritual.
A bedtime journal for people who never kept a diary going.
One line is enough
No scores, no graphs, no streak pressure.
"Kind of a tiring day" — that's plenty.
Gently pick how tonight feels (tired, anxious, proud…) and what you'd like (just listen, a step for tomorrow…) — or skip it.
Let the day out in one line, and end it quietly.
Every night becomes a card
Your words create a card that belongs to that night alone.
Morning sun, crescent moon, shooting stars, the Milky Way… night skies quietly gather over time.
Sometimes a shimmering rare one. Which sky you'll meet — that's the surprise.
Look back over the last 7 nights for free; Plus opens your whole history.
A letter from your star child in the morning
Your star child keeps the words you wrote until morning.
The next morning (7:00 by default), a short letter arrives, written for the you of that night.
No AI writes it — one letter is chosen from a set of gentle, pre-written lines. What you wrote is never analyzed or sent anywhere.
The first three morning letters are free; with Plus, a letter arrives every morning.
Your mind constellation over 7 days
Only the feelings you chose over the last 7 days are gathered, quietly and on your device, into a constellation to look back on.
This is not a diagnosis — just a gentle way to see your week.
A simple view is free; a closer look comes with Plus.
Your star child grows
It grows with every night you write.
While you sleep, it goes on a little journey — and comes back with a souvenir story.
Give it a gentle tap, and it smiles back.
Tomorrow's first small step
From what you wrote, it gently surfaces one small step for tomorrow.
The rest can wait. Sleep well.
Look back, gently
Search by words, tags, or date, and add optional tags (work, family, parenting…).
You can also share a card as an image — the words you wrote are never included in it (you preview first).
Everything stays on your device
No account. No server. No one sees what you write.
Your words, your letters, and your constellation live only on your iPhone.
No streaks to break, no guilt. Miss a night — your star child will simply be waiting.
