Getting your weight in — and never losing it

The tracker keeps everything in your browser — nothing is uploaded, no account needed. This guide shows you how to pull in your history from any scale, log new readings automatically, and — most importantly — keep a backup.

Export from Renpho

The Renpho Health app can export your weight history as a CSV:

1. Open the Renpho Health app and go to the Trends tab, then tap Weight.
2. Tap the clock / history icon in the top-right corner.
3. Tap Select Data → “…” → Select all data.
4. Tap the share icon (a square with an up-arrow) in the bottom-left. Choose how to send yourself the file — it comes out as a .csv.
5. Save that CSV to your phone or email it to yourself, then import it below.

Renpho's export layout changes between app versions; if you don't see these exact words, the alternative path is to sync Renpho into Apple Health or Google Fit and export from there — see the sections below.

Export from Xiaomi (Zepp Life / Mi Fitness)

Xiaomi scales don't offer a tidy CSV, but they sync cleanly into the big health apps — which is exactly what we want, because those export beautifully:

• iPhone: in Zepp Life → Profile → Add accounts → Apple Health, and turn on Weight. Now follow the Apple Health steps.
• Android: in Zepp Life / Mi Fitness connect Google Fit (or Health Connect) and enable weight sync, then use the Google Fit steps.

Export from Apple Health (iPhone)

1. Open the Health app → tap your profile photo (top-right).
2. Scroll down and tap Export All Health Data. It builds an export.zip (this can take a minute).
3. Save / AirDrop the zip to a computer and unzip it — inside is export.xml.
4. Import that export.xml. We read only your body-weight records and ignore everything else.

Export from Google Fit (Android)

1. Go to Google Takeout (takeout.google.com), deselect all, then select just Fit.
2. Create the export and download the archive.
3. Inside, look under Fit → Daily activity metrics for the CSV files — they include a weight column.
4. Import the CSV. (A plain date,weight CSV from any source works too.)

Import a file into the tracker

Open the Weight Tracker, scroll to Import & backup, and drag your file onto the drop zone (or tap to choose it). We auto-detect the format — Renpho CSV, Apple Health XML, Google Fit CSV, a generic date,weight CSV, or a SpecEnvoy backup — convert everything to your chosen units, and merge by date so re-importing never creates duplicates. Nothing leaves your device.

Log your weight automatically every morning

Manual logging is easy to forget. How hands-off you can get depends on your device — but they all use the same trick: the tracker accepts a “quick-add” link that logs a reading when it's opened, so any automation that can open a URL can log for you.

• iPhone — a free Shortcut reads your latest weight from Apple Health and opens the link each morning (steps below). Any scale that syncs to Apple Health (Renpho, Xiaomi, Withings…) then logs itself.
• Android — an automation app (HTTP Shortcuts, Tasker, or Macrodroid) reads weight from Health Connect and opens the same link. See the Android note below.
• Computer (Windows / Mac / Linux) — there's no phone-style health feed, so this is manual: import your scale's export, or just type today's number into the tracker (a couple of seconds). Still private, still yours.

The quick-add link looks like:

https://www.specenvoy.com/data/health/weight/#add?kg=95.3&d=2026-07-06

(use lb= instead of kg= if your Health app is set to pounds). Opening that link adds the reading once and then cleans itself up.

On iPhone — the Shortcuts recipe

1. Open the Shortcuts app → Automation tab → + → Time of Day. Pick a time after you usually weigh in (say 9:00 AM), Daily, and set it to Run Immediately (turn off “Ask Before Running”).
2. Add action Find Health Samples → type Body Mass, sort by End Date, order Latest, Limit 1.
3. Add Get Details of Health Sample → Value (this is your weight number). Add another for Start Date if you like.
4. Add a Format Date action on that date → custom format yyyy-MM-dd.
5. Add a Text action and type the link, dropping in the variables:
   https://www.specenvoy.com/data/health/weight/#add?kg=[Value]&d=[Formatted Date]
6. Add Open URLs with that Text. Done — each morning it opens the tracker, logs your weight, and you'll see the celebration if you cross a milestone.

This is a friendly tracker, not a medical device. Talk to a doctor about your healthy weight and any significant changes — and if weight is a source of real distress, please reach out to someone you trust.
