Health Data: Viewer & Export
Sleep, Heart Rate & HRV to CSV
See what your wearables and apps record. Follow each measurement back to its source, inspect its timing, and explore heart-rate history alongside sleep and HRV.
Health Data is an on-device health-data explorer for iPhone and Android, from 37°N.
Understand the timing.
Time-based plots show when each record was recorded and which app or device supplied it. Health Data reads only while it’s open; it doesn’t run in the background.
Keep your own copy.
Export the records loaded in the explorer as CSV. Reads are capped at the newest 500 records per type; this is a snapshot, not a complete history or backup. Read receipts show incomplete or restricted coverage. You choose where the exported file is saved.
Open the app. Explore your data.
Health Data is free to use. No account, sign-in, email address or subscription is required. It works offline from the first launch and keeps your health records on your phone.
You choose which records Health Data can read through Apple Health or Health Connect permissions.
