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 save the file to your phone, then choose it in Cocoon’s import screen. A computer is optional. 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
- Save the export to Files on your iPhone or Downloads on Android. Keep the original file as a backup.
- In Cocoon, open Care → Import from another app. On older versions use Settings → Data & privacy → Import data. You can also use app.getcocoonapp.com/import in a browser.
- Choose your export file. Check the detected app, the baby receiving the records, the dates and any missing fields in the preview.
- Confirm when the preview looks right. Already-imported records are skipped; unreadable rows are listed. You can undo the import straight afterwards.
- Imported measurements appear in Growth; care logs appear in the Journal. To sync between devices, sign in to the same account and select the same baby and family.

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?
Cocoon skips entries it recognises from earlier imports. Check the duplicate count in the preview, especially if you edited the export or changed its date format.
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. Save the export to Files on iPhone or Downloads on Android, then choose it in Cocoon’s import screen. A computer is optional. To sync to another device, sign in to the same account and select the same baby and family.
