OneLine Journal: Daily Diary

Journaling shouldn't feel like homework. OneLine Journal turns reflection into something as easy as texting a friend — except the friend is future you.

HOW IT WORKS Open the app and drop a line whenever something happens — a thought, a win, a worry, a joke you don't want to forget. Each entry lands as a chat bubble on today's timeline, so a busy day can become five short entries instead of one you never get around to writing.

Yesterday, and every day before it, stays exactly as you wrote it — past entries are read-only, so your journal stays an honest record instead of something you go back and edit later.

BUILT TO KEEP YOU GOING • Streak tracking that counts consecutive days you've written, right at the top of your feed • A scrollable day strip and month view so you can jump back to any date • "On this day" memories that resurface what you wrote on this date in past years • An Insights screen with your current and longest streak, entries this week and month, your most active weekday, and how long you've been journaling • One gentle evening reminder — and only on the days you haven't already written

PRIVATE BY DESIGN Every entry is encrypted on your device with AES-256 before it ever leaves it, using a key held in your device's Keychain — we only ever store ciphertext, not your words. Start as a guest and everything stays on-device; sign in with Apple whenever you want your journal backed up and synced, with nothing lost in the switch.

NO CLUTTER No ads, no social feed, no likes. Just you, today, and one line at a time.

Delete a single entry, edit today's line, or permanently erase everything from Settings whenever you want — your data is yours.
