## What is One Line a Day?

The hardest part of journaling is doing it tomorrow. OneLine fixes that: one line about today, and you're done.

Thirty seconds a night. That's the whole habit. No blank-page dread, no guilt about writing too little — one honest line is the point. Keep it up and something quietly wonderful happens: next year, on this exact day, OneLine shows you what you wrote today. Then the year after. Your ordinary days become a story you get to reread for the rest of your life.

WHY ONE LINE WORKS
• 30 seconds. Small enough that you'll actually do it every day.
• Streaks keep you going — and skipping a day never wipes your history.
• A gentle daily reminder, at the time you choose.
• Stuck? A thoughtful daily prompt gets you started.

ON THIS DAY
Every day, see the lines you wrote on this date in past years. It's the best 30 seconds of your morning — one year of writing makes every day a tiny reunion with who you were.

COMPLETELY PRIVATE
Your journal never leaves your iPhone. No account. No cloud. No tracking. Nothing to hack, nothing to leak. Optional Face ID lock keeps it for your eyes only.

ONELINE PRO
The app is free to use every day, and your last 30 days are always visible. Pro keeps every line forever, unlocks On This Day memories, full-text search, CSV export, and Face ID lock. Get it yearly with a 7-day free trial, or once forever with Lifetime.

Start tonight. One line. Future you is already grateful.
