Serendipity Diary is a quiet page that is always with you — for the good days, the heavy ones, and everything in between. A goodnight thought, a trip, a dinner, a sudden rain: write it down, and the day takes shape. CAPTURE THE MOMENT A clean, friendly editor that makes writing feel effortless. Bold, headings, lists, quotes and tables — everything falls into place as you type. Drop photos, videos and voice notes right into the page, with a word count that quietly keeps up. REMEMBER HOW IT FELT Mark each entry with your mood and the weather, keep the place it happened, and add a few tags. When you look back, you won't just read the words — you'll meet the person who wrote them. START FROM A TEMPLATE Save the formats you use most — morning pages, evening reflections, travel logs — and begin each new entry from a familiar shape. Keeping the habit gets easier. FIND YOUR WAY BACK Days with entries light up on the calendar; tap one to return to it. Search your whole diary with a single word, and pin the entries you never want to drift far. SEE HOW FAR YOU'VE COME Entries, words and writing days quietly add up to milestones. One day you'll look back and realize how long you've been writing. NEVER LOSE A WORD Turn on cloud backup to keep your diary and photos safe and in sync across your devices. Export a complete archive anytime, or move everything to a new phone over your local network. Your memories travel with you. FOR YOUR EYES ONLY Lock the app with your face, fingerprint or passcode. Keep your most private pages in a separate, individually locked private space — a passing glance reveals nothing. The private space never joins cloud sync, so what you write there stays only on this device. SHARE ON YOUR TERMS Export an entry as Markdown or plain text, or share it with someone who matters — always your choice. Today deserves a page of its own. Open Serendipity Diary and begin. Subscription terms: Serendipity Diary offers an optional auto-renewing subscription. The price and billing period are shown in the app before you confirm. It renews automatically for the same period unless canceled at least 24 hours before the current period ends. Manage or cancel anytime in your app store account. --- Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://getflutterapp.web.app/diary/privacy.html
