YesterYears – Diary, where every year's today reappears One sentence a day. Light as a habit. Have you ever felt this way? You want to keep a diary, but you get stuck on "how much," "what to write," and "will I stick with it" — so you start and never pick it up again. You try to find what you wrote on this day last year, only to scroll endlessly through your timeline, with no "on this day" moment. Diary apps keep piling on features — social feeds, check‑ins, leaderboards — distracting you from the quiet act of writing just one sentence. YesterYears makes recording light enough, and looking back deep enough. Open the app, write a line, close it — like scribbling a note in a notebook. - Anchor by month‑day, look back vertically Your entries from different years meet on the same page. The current year is highlighted, with past years listed below. Swipe left or right to move through any of the 365 days around today. Record today, and see what you wrote on this day in years past. - Calendar overview A two‑month view shows records for two months at a glance. Days with entries are marked with a dot; tap to go directly to that day's detail page. - Light, not a burden One sentence per day — even one word. Customizable character limit (50–200). No formatting pressure, no templates. Over 365 writing prompts in both Chinese and English lower the barrier to start. Entries save automatically as you type — no manual submission needed. - Local first, privacy first Data is stored locally on your device by default — no upload, no analysis. Optional iCloud sync lets you continue across devices. Export all entries as JSON. No account system, no third‑party tracking, no ads, no subscription gimmicks. - Restrained design A warm paper‑like background stays soft in both light and dark modes. Clay‑toned accents, serif fonts for body and dates. Card layout, gentle shadows, continuous rounded corners — quiet and low‑pressure, making you want to come back every day. - Widgets and quick writing Home Screen widgets (small and medium) let you start writing with one tap. Quick‑write via notifications, widgets, or deep‑link overlay — write and close without interrupting your current context. Daily reminders can be customized to fit your routine. - Multi‑platform, one habit Supports iOS (iPhone / iPad), macOS, and visionOS. With iCloud sync, it's natural to write on desktop and jot on mobile. Open, write one line, close — just like a line in your notebook. A year later, you'll smile at the person you are today.
