About this app
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 one 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, your calendar fills in - 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 one line a day: daily journaling stripped down to the part that actually sticks.
Features:
- One sentence a day - the lowest-effort daily journal that actually sticks
- Voice input - speak your sentence instead of typing it. Tap the mic and dictate
- Your timeline, as a calendar - see every day you've written at a glance, month by month and tap any day to read that sentence
- 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.
Free to use. Start tonight.

Speak instead of typing. Tap the microphone in the writing box to dictate your sentence - on Today and during setup.
This is why the app now asks for the Microphone permission. It's used only when you tap the mic and we never receive or store your audio.
Also in this update:
• A new app icon
• A "Send feedback" option in Settings
• Layout fixes on tablets and foldables
