WHY DAN HANA

Not twenty things,
just one. That's enough.

Focusing on the single most important thing today —
that's the smallest, strongest habit there is.
A steady day beats a perfect one in the long run.

FEATURES

Small, but deep

A single promise

Write the one thing for today. A line is enough. Warm, like a paper card.

Days you kept

Calendar, graph, and streaks let you see your quiet consistency. Empty days are fine.

A weekly letter

Every Sunday night, an AI letter quietly reflects on your week. Notice the small changes.

VOICES

Stories from early users

Every other to-do app felt heavy. With Dan Hana I only write one line a day — so I actually use it every day.

Chae-Eun · Designer

I look forward to the Sunday letter. Something about it gently puts the week in order.

Hyun-Woo · Developer

“One is enough” loosened something in me. That's exactly why I keep showing up.

Eun-Jin · Writer

Today, one is enough.

We'll quietly hold your gentle day with you.
