The daily journal you'll actually keep.

No essays. No prompts. No pressure. Just one sentence before you sleep and a timeline of your life that builds itself.

Most journals and diary apps fail, because they ask too much. One Sentence Day asks for a single line a day. The meeting that went well. The coffee that didn't. The thing nobody else knows happened. Thirty seconds, then close the app.

A year from now you'll have something no photo album can give you: a full scroll through every version of yourself, in your own words - like a five-year diary, but one line at a time.

How it works:
1. A gentle daily reminder arrives at night, when you usually wind down.
2. Write one sentence about your day. A highlight, a worry, a small gratitude - anything.
3. Day by day, a timeline builds - your life, one line at a time.

Why One Sentence Day works:
The best journal is the one you keep. By asking for a single sentence instead of a full page, One Sentence Day removes the friction that makes most diary and journaling habits collapse within a week. It's daily journaling stripped down to the part that actually sticks.

Features:
- One sentence a day - the lowest-effort daily journal that actually sticks
- Your timeline - every entry, organized by year, newest first
- Memories - see what you wrote on this day in past years, like a living five-year diary (the older your journal, the more powerful this gets)
- Streak tracking - keep the habit, with one grace day a month so a single missed night doesn't break your streak
- Daily reminders - a quiet, customizable nudge at a time you choose
- Cloud sync - your journal is safe and survives reinstalls and new phones
- Private by default - your words are yours, always

Whether you want a gratitude journal, a daily diary, a line-a-day memory keeper, or simply a place to remember your life, One Sentence Day is the journaling app you'll still be using in ten years.
