How to Export Weight Data from Apple Health

Apple Health records every weight reading you take — whether from a Withings, Eufy, Renpho, or Garmin smart scale, another connected device, or manual entries. But when your dietician, endocrinologist, OB-GYN, or bariatric surgeon asks for your weight history, getting that data out in a usable format is not straightforward.

This guide shows you how to export your weight readings as a clean PDF or CSV file using vitalina, a free iPhone app that reads your Apple Health data and generates doctor-ready reports in under two minutes.

Why Apple Health's built-in export does not work for weight

Apple Health does let you export your data as XML, but the result is a single file containing every health data point your iPhone has ever recorded. There is no way to filter by metric, so your weight readings are buried alongside steps, sleep, nutrition, and everything else. There is also no date range control — you cannot ask for just the last three months. The file is not readable by a human, and there are no charts or summaries.

Apple doesn't hand you the XML directly either. You get an Export.zip archive that you have to unzip on a computer. Inside is a folder called apple_health_export, and the full Export.xml sits inside it alongside supporting files. For long-time Apple Watch users that XML can easily reach 2.9 GB — 11 years of continuous health data in one file.

Even if you have only been weighing in for a few weeks, the full export is typically hundreds of megabytes. It is not something you can email to your doctor or review before an appointment.

vitalina solves this by reading your Apple Health data locally on your iPhone and letting you export just your weight data — for any date range you choose — as a PDF or CSV.

What you'll need

• An iPhone running iOS 16 or later
• Weight readings recorded in Apple Health (from a connected smart scale or manual entries)

Step 1: Download vitalina

Download vitalina from the App Store. It's free to use with no account or sign-up required.

Step 2: Allow access to Apple Health

When you first open vitalina, tap Allow Health Access and confirm the permissions in the Apple Health prompt. vitalina only requests read access — it cannot modify or delete your health data.

Your data never leaves your device. vitalina processes everything locally on your iPhone with no cloud uploads, no tracking, and no analytics.

Step 3: Pick a Quick Export template or create a custom export

On the main screen, you'll see a set of one-tap Quick Export templates. Tap one of the weight-focused templates to start an export pre-configured for clinical use — body weight selected, PDF format, ready to go.

If you prefer full control over the date range and which body measurements are included, tap Create Custom Export instead. The rest of this guide walks through the custom export flow.

Step 4: Select Body Weight

In a custom export, you'll see all available health metrics grouped by category. Under Body Measurements, select Body Weight. This exports every weight reading stored in Apple Health for the period you'll choose in the next step.

You can also add related body-composition metrics at this step — for example, BMI, Body Fat Percentage, or Lean Body Mass — if your doctor has asked for a broader picture. These are especially useful for weight-loss programs, post-bariatric-surgery follow-ups, and hormone therapy monitoring.

Step 5: Pick a date range

This is where vitalina makes a real difference over Apple's native export. You can choose exactly how far back to go:

• Last 7 days and Last 14 days — available for free
• Last 30 days, 3 months, 1 year, and All time — available with vitalina Pro
• Custom date range — pick any exact start and end date with Pro

If your dietician, endocrinologist, or OB-GYN has asked for several months of weight history — for prenatal visits, diabetes management, or eating disorder recovery — the Pro upgrade is a one-time purchase that unlocks all extended date ranges.

Step 6: Choose your export format

For weight data, two formats are most useful:

• PDF: The best format for doctor appointments. Includes a trend chart showing your weight over time, a full table of readings with timestamps, and clean formatting your doctor can read without any technical knowledge. You can email it, AirDrop it, or print it before your appointment.
• CSV: Opens in Excel or Google Sheets. Ideal if you or your doctor wants to do detailed analysis, build custom charts, or import the data into another tool.

Both formats are available for free.

Step 7: Tap "Export Now"

Tap Export Now. vitalina reads your weight data from Apple Health, formats the export, and generates your file — usually within a few seconds.

Step 8: Share with your doctor

Once your export is ready, you'll see a full preview of the file. From here, tap Export to open the iOS share sheet, where you can:

• Email it to your doctor or care team before your appointment
• AirDrop or share via Messages to anyone nearby
• Save to Files on your iPhone or iCloud Drive
• Print a physical copy to bring to the clinic

Which smart scales sync to Apple Health?

vitalina exports any weight readings stored in Apple Health, regardless of where they came from. This includes:

• Withings — Body, Body+, and Body Scan smart scales
• Eufy — Smart Scale P2 and C1
• Renpho — smart scales via the Renpho Health app
• Garmin — Index S2 smart scale
• iHealth — connected smart scales
• Fitbit Aria — via third-party sync tools
• Manual entries — readings entered by hand in the Health app

If the reading appears in Apple Health under Body Measurements → Weight, vitalina can export it.

How much does vitalina cost?

vitalina is free with 5 unique exports and date ranges up to 14 days. vitalina Pro is a one-time purchase (no subscription) that unlocks unlimited exports, extended date ranges up to all time, and Shortcuts automation. Re-exporting the same configuration is always free.
