How to move from Day One to Cocoon
Bring your Day One entries — words, photos and all — into Cocoon's journal, beside the daily log.
Export your data from Day One, then open app.getcocoonapp.com/import on a computer — or Import data in the app — and add the file. Cocoon recognises it as Day One, shows a preview, skips duplicates and brings across journal entries, tags, places, photos, videos and audio recordings.
What you need
Day One's JSON export, as a .zip.
Step 1 — export from Day One
- Export your data from Day One: Cocoon reads Day One's JSON export, as a .zip.
- Save the file somewhere you can reach it — email it to yourself, or save it to your Downloads or Files.
Step 2 — import into Cocoon
- On a computer, open app.getcocoonapp.com/import and sign in with the same account (or open Settings → Data & privacy → Import data on your phone).
- Drag your export file in, choose it, or paste from the clipboard. Cocoon detects which app it came from.
- Check the preview: what was found, which day each entry will be filed on, and whether dates were written day-first or month-first.
- Confirm. Duplicates are skipped, anything that couldn't be read is listed, and you can undo the whole import straight afterwards.
- Everything syncs to your phone and to the caregivers you share with.

Common questions
Does Cocoon keep my Day One photos?
Yes — Day One entries come across as journal entries with their photos, videos, audio recordings where the export includes them, on the day they were written.
Will importing from Day One create duplicates?
No. Cocoon skips anything it has already imported, so importing the same file twice is safe — handy if you keep using your old app for a few days while you switch.
Can I undo an import from Day One?
Yes. Straight after an import, tap Undo this import and everything it added is removed. The preview before you confirm also shows what was found and which day each entry will be filed on.
Do I need to do this on a computer?
No, but it's usually easiest: exports tend to arrive by email or land in a Downloads folder. Open app.getcocoonapp.com/import on a computer, or use Settings → Data & privacy → Import data on your phone — either way, it syncs everywhere.
The tracker that also remembers
Nap and feed windows from day one, a sleep program, growth percentiles, a photo journal and family sharing — every feature free right now, and your data yours to export any time.
