Margin One Line

The 15-second journal. One line, one mood, and once a month Margin reads your month back to you. Private by design — your words stay on your phone.

Margin, One Line a day. That's the whole idea.

Most journaling apps ask for too much, so the habit dies in a week. Margin asks for one sentence and one tap. Fifteen seconds before bed, and you've kept it up.

WRITE Open the app, write a line about your day, tap how it felt. Done. No prompts to answer, no pressure, no blank page staring back.

LOOK BACK Your entries live on one quiet timeline. "On this day" surfaces what you wrote a year ago, so consistency actually pays you back.

YOUR MONTH, READ BACK TO YOU This is the part no other one-line journal does. Once a month, Margin reads everything you wrote and writes back — the patterns, the steadier stretches, one thing you might not have noticed. Not generic advice. Built from your own words.

PRIVATE BY DESIGN There's no account and no sign-up. Your journal is stored on your phone, not our servers. We can't read it. The only thing that ever leaves your device is the month you personally ask us to reflect on — and we don't keep it.

FREE, AND IT STAYS FREE Writing, moods, the timeline, "on this day," reminders, and export are all free, forever. Margin Premium adds the monthly reflection — twelve a year — for those who want it.
