Bring your Apple Health sleep data.
From your iPhone to a private sleep workspace, without sending your export to us.
Make your export
On your iPhone, open Health, tap your profile picture or initials, and choose Export All Health Data. Save the exported ZIP file somewhere you can access from your browser. Labels may vary by iOS version.
Open it locally
Choose Import sleep data in KnowNaps and select the ZIP, or extract export.xml and import that file. KnowNaps reads sleep records in this browser. The original export may contain other health information; it is never uploaded by this workspace.
Check the result
Review the detected nights and any import warnings. Apple Health may contain records from multiple devices or apps. Overlapping sleep intervals are merged to avoid counting the same time twice. Times are read using the offset in the export.
If the file is too large
This workspace accepts files up to its displayed import limit. Large archives can use substantial memory. Try a sleep-only CSV export using the template, or use a desktop browser. Keep the original export safely on your device.
General education only. Persistent sleep problems deserve a conversation with your healthcare professional.
