Dayline - One Line a Day Diary

One line before bed. That's it. No account, no cloud, no pressure — your diary lives only on your phone. A year from now, today comes back to you.

Most diary apps ask too much. An account. A cloud backup. Twenty minutes of your evening.

Dayline asks for one line.

Open the app, write a single sentence about today, and close it. Five seconds. That's the whole habit. And because it's only one line, you'll actually keep doing it — day after day, until something remarkable happens: "one year ago today" starts showing up, and your past self begins talking to you.

YOUR DIARY NEVER LEAVES YOUR PHONE • No account, no sign-up, no cloud • Everything is stored only on your device • Lock it with Face ID • Export to CSV or text anytime — your words are yours

A HABIT THAT KEEPS ITSELF ALIVE • Streak counter for consecutive days • A gentle daily reminder at the time you choose • Home Screen and Lock Screen widgets — write without even opening the app

MEMORIES, THE HEART OF DAYLINE • See what you wrote one year, one month, and one week ago — every single day • Browse your past in a calendar or a card timeline

DESIGNED LIKE PAPER, NOT LIKE AN APP • Warm, ink-on-paper design in light and dark • Choose the paper tone you write on: Paper, Butter, Blush, or Sage

Dayline is free, supported by small ads. Extra paper tones can be unlocked by choosing to watch an ad — never required.

Start tonight. One line is enough.
