There is no fourth line.
To-do lists grow without end, and a long list makes nothing matter. THREE goes the other way. You cannot go past three. Choosing is what shapes the day.
One or two is fine. Unfinished things do not roll over to tomorrow. It is a record, not a to-do list.
Widgets · Lock Screen
Get through the day without opening the app.
See what is left on your Home Screen and Lock Screen, and check it off right there. When one is left, it quietly tells you.
It does six things.
Today’s three
Write, reorder, check. There is no fourth line. Last year’s three show faintly below.
Ladder
Who you want to be → this year → this month → this week. One per rung; finish it or let it go before you pick the next.
A 66-day circle
A habit to build fills the circle one stroke a day; a habit to break fills it with passing time. In 66 days the circle closes.
Three morning breaths
Thirty seconds the first time you open it each day. Three breaths and your affirmation, then today. You can turn it off in Settings.
Sunday review
Look back on this week’s one and leave a line. No scores, no streaks.

See what is left and check it off without opening the app. Only the reminders you turn on.
I am someone who
writes a little every day.
Write for 30 min


Press and hold for a stroke. Empty days are part of the circle too.
Three breaths,
then write today.
Once, the first time you open it · about 30 seconds
This week’s one,
how did it go?
Accent color
Black, white,
and a drop of ink.
Pick one of eight fountain-pen inks. Checks, the last-one note, widgets and the Lock Screen all take the color. Tuned to stay readable even in small type.

FAQ
Can I really only write three?
Yes. There is no fourth line. One or two is fine too.
What happened to ONE and ensō?
They are now part of THREE 2.0. Use the ladder and the 66-day circle on THREE’s one screen. Leave them off, and THREE stays as it was.
What happens to unfinished things?
They stay in that day’s record. The next day, one tap on “Bring over yesterday’s” moves them into empty lines.
When does a new day start?
At 4 a.m. by default, so 1 a.m. for a night owl is still today. You can change it in Settings.
Does it work across devices?
Yes, through iCloud on the same Apple Account. It is on from the start, and you can turn it off in Settings.
How much is it?
Today’s three, widgets and history are free. The ladder, the 66-day circle and morning breaths are THREE Pro, free to try for 30 days.
Which languages?
Korean, English, Japanese, Simplified Chinese and Spanish.
