OneLine — Daily Journal
One line a day, private diary
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Your life story, one line at a time.
OneLine is the journal for people who don't have time to journal. Write a single line about your day — it takes five seconds — and watch your life story build itself, one day at a time.
WHY ONE LINE?
Big journaling apps fail because they ask too much. OneLine asks for one sentence. That's small enough to do every single day — and a year from now, you'll have 365 tiny memories you'd otherwise have forgotten.
• FIVE SECONDS A DAY — One line, an optional mood, done. No pressure, no blank-page anxiety.
• BUILD A STREAK — Show up daily and watch your streak grow. Small habit, big memories.
• ON THIS DAY — Relive what you wrote a year ago, right when you open the app.
• WIDGETS — Your streak and memories on your Home Screen and Lock Screen.
• DAILY REMINDER — A gentle, friendly nudge at the time you choose.
• 21 LANGUAGES — Use OneLine in the language you think in.
• PRIVATE BY DESIGN — Your journal lives on your device. No account, no cloud, no tracking.
ONELINE PRO
Go Pro to unlock your full history and "On This Day" flashbacks, attach a photo to each day, use every widget, export your year as a beautiful PDF book, and lock the app behind Face ID. Weekly, monthly, or one single lifetime purchase — yours forever.
Start tonight. One line. Five seconds. Future-you will thank you.

• Save your streak — miss a day and you get one more day to write it in, with a morning reminder that says so.
• Share a line as a picture, made on your device for a story or a post. Nothing is uploaded.
• Lower Pro prices, and a place on the paywall to enter a discount code.
• A calmer first run, a rebuilt lock screen and smaller fixes.
