About Diary: One Line a Day Journal
One line a day. That's the whole idea. A private five-year micro diary that takes ten seconds a night — and one day shows you what you wrote on this exact date one, two, five years ago. Write one short line about today, auto-dated. Tomorrow, another. A month from now you have a quiet calendar of your days; a year from now, today comes back to meet you. That's it. No prompts to answer, no streaks to keep, no guilt for a missed day — a missed day just stays empty. ONE LINE A DAY - A single 280-character entry per day, dated for you - Editable the same day — then it's part of the record - A beautiful, calm, paper-warm design with serif writing - Add a photo to any day's entry - Color themes, including a dark mode ON THIS DAY - YOUR MEMORY KEEPER - See the same date across every past year, stacked on one page - "One year ago... two years ago... five years ago..." - A five-year diary that quietly writes itself A WHOLE MONTH AT A GLANCE - A soft month calendar with a dot on every day you wrote - No charts, no percentages — just your days A PRIVATE DIARY WITH LOCK - Optional Face ID / Touch ID app lock - An offline journal — no account, no sign-in, no cloud - Nothing is ever uploaded; your words stay on your phone CALM BY DESIGN - One gentle daily reminder, at a time you choose — never a streak, never a nag - No badges, no goals, no gamification - Just a quiet place for your daily journal YOURS TO KEEP - Look back through your entire diary, any time - Export your whole diary as a PDF or plain text, any time Whether you call it a one line a day journal, a micro journal, a memory keeper, or simply your diary — this is the simplest way to remember your life, ten seconds at a time.
