Onceday: Daily Photo Journal

Onceday is a private daily journal built around one deliberate moment per day. Capture a photo with the camera or choose one from your library, record up to 30 seconds of audio, or write a few words. Add a mood, tag, place, and person when they matter. A fresh reflection prompt helps you notice something worth keeping without turning journaling into another task list. FOLLOW THE STORIES THAT RETURN Continuity Map connects related moments already in your journal. Explore recurring people, tags, and places; see how many months a thread spans; review its timeline; and notice whether its recent tone is brighter, steady, heavier, or still developing. Every result is calculated on your device from entries you can open and verify. CHECK THE ARCHIVE YOU ARE BUILDING Archive Integrity scans your journal for duplicate days, broken photo or audio links, future dates, empty moments, missing people, and unrecognized mood values. It never edits or deletes anything automatically. Open affected moments for review, rescan when you are ready, or export a dates-and-counts report that excludes journal text, photos, and audio. BUILT FOR LOOKING BACK • Calendar archive with full-text search • Filters for mood, tag, and place • On This Day memories from earlier years • People timelines with age-at-the-moment context • On-device Archive Integrity checks with source-level drill-down • Year heatmap, monthly consistency, mood patterns, and streaks • Printable PDF yearbook with six cover styles • On-device Year-in-Review video • CSV export for spreadsheets PRIVATE BY DESIGN Onceday has no account, advertising, tracking, subscription, or cloud service. Journal entries stay on your device. Face ID, Touch ID, or the device passcode can protect the app, and a complete offline backup file gives you a portable copy you control.
