Lumi: One Line Journal

One emoji. One line. That's a whole day.

Lumi is the journal for people who never keep a journal. No blank page
staring back at you, no guilt about the entry you "should" write. Pick a
mood, type a single sentence, and you're done. The whole thing takes ten
seconds — which is exactly why you'll still be doing it a year from now.

YOUR YEAR, PIXEL BY PIXEL
Every day you log becomes one colored square in a grid of your whole year.
Watch it slowly fill in. Tap any past square to read — or quietly fix —
what that day was.

NEVER LOSE A WORD
Your sentence saves itself as you type. Close the app mid-thought, drop
your phone, run out of battery — it's already saved.

INSIGHTS INTO YOU
See the shape of your year: your moods over time, your patterns, your
brightest days, your streaks — all from your own daily lines.

A REFLECTION EVERY SUNDAY (optional)
Once a week, Lumi can read back your own entries and write you a short,
warm reflection — the gentle pattern a friend would notice. It's powered
by AI, honest about being AI, and the only part of the app that costs
anything.

The journal itself is free. Forever. You only pay if you want the weekly
reflections and deeper insights.

BUILT TO BE PRIVATE
- No account. No sign-up. No email.
- Your entries live on your device.
- We don't track you. Analytics are anonymous counts, nothing linkable.
- When you ask for a reflection, that week's entries are read once and
never stored on any server.
- Export everything to CSV whenever you want.

A GENTLE NUDGE, NOT A NAG
One optional daily reminder, at a time you choose. Miss a day? Nothing
breaks. Your streak encourages you, it never punishes you.

Small app. Small habit. A surprisingly big picture by December.
Start tonight. One line.
