Onceday

About Onceday

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.

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.
