Health Connect

Your scale, your apps, one record.

Health Connect is Android’s on-device health hub. 4.2 can read weight and body composition from it — and optionally write your logged entries back, so the rest of your health apps see them.

What syncs

Weight first. Body composition when available.

A smart scale can write several records to Health Connect. The app imports the weight and enriches it with the body-composition values your scale or health app provides.

  • Weight is the core reading; the app can work without body-composition data.
  • Body fat, lean mass, body water, and bone mass are optional enrichments.
  • Permissions are granular — you choose what to share.
  • Imported records are stored locally on your device.
The accuracy of an imported reading depends on the source scale or app. Weight Track Assistant records what Health Connect provides; it does not recalibrate a device.

Weight

The core reading from a smart scale or another health app.

Body fat

Stored as a percentage when the source provides it.

Lean body mass

Converted into the app’s body-composition columns.

Body water

Imported when available and attributed to the right profile.

Bone mass

Optional body-composition context, not a diagnosis.

How it works

Connect once. Then let the record fill in.

Health Connect is not a cloud account. The connection is between your device, Health Connect, and the app.

Step 1

Open Data sync

Choose Health Connect as the source and connect it.

Step 2

Grant read access

Allow weight, and optionally body composition. You can change this later.

Step 3

Sync or import

Run a sync now, or import all history with the extra permission.

Step 4

Review the record

New readings appear in your local history and trend. Out-of-range records are held back.

Writeback

Your logged entries can feed the hub, too.

Optionally, save the weight and body-fat entries you log in 4.2 back to Health Connect. Other apps you allow can then read them.

  • Off by default; you choose whether to write back.
  • Writeback covers weight and body fat, not every module.
  • You control which apps can read Health Connect data.
  • Disconnecting does not delete the original Health Connect records.
How privacy works
On-device

Not a cloud account.

Health Connect lives on your Android device. Weight Track Assistant reads and writes locally; it does not upload your health records to a Weight Track Assistant server.

Disconnect gives you a choice: delete the imported readings from the app, or keep a local copy. Either way, the original data in Health Connect stays untouched.

Control

A connection you can pause, fix, or remove.

Sync should not be a one-way surprise. The app shows the connection state and gives you a clear action.

Sync now or automatic

Run a sync when you want, or let the app keep the connection current.

Re-authorization

If Android revokes access, the app tells you and waits for you to re-authorize.

Profile attribution

“Who mainly weighs on this scale?” files incoming records under the right local profile.

Out-of-range guard

Records outside a plausible range are held back; nothing is changed silently.

Pause & disconnect

Pause sync, or disconnect and choose whether to delete imported readings.

Import all history

A separate permission for older data; grant it only if you want the full history.

Not medical advice. Health Connect and smart-scale readings are measurements, not a diagnosis. Talk to a qualified clinician about changes that concern you.

Health Connect questions.

Is Health Connect a cloud sync?
No. Health Connect is Android’s on-device health data hub. Weight Track Assistant reads and writes through it locally; the app does not create a cloud health account or upload your records to us.
What data can the app read from Health Connect?
Weight and body composition: body fat, lean body mass, body water, and bone mass. Weight is the core permission; body-composition permissions are optional, and missing them only means fewer enriched columns.
Does it import my entire history?
By default, Android allows reading the last 30 days. “Import all history” asks for one extra permission; you can grant or decline it at any time.
Does the app write back to Health Connect?
Optionally, yes. “Save my entries to Health Connect” writes the weight and body-fat entries you log in 4.2 back to Health Connect, so other apps you allow can read them. You can turn this off.
What happens if I disconnect?
You can delete the imported readings from the app or keep a local copy. Original data in Health Connect is untouched either way.
What if Health Connect access is revoked?
The app shows “Needs re-authorization,” sends a private status notification if you allowed notifications, and resumes after you re-authorize. It does not silently retry or discard your local data.
Do I need Health Connect to use the app?
No. The app works without it. Health Connect is optional and must be available on your device; if it is not installed, the app offers an install link.
Is my Health Connect data uploaded to Weight Track Assistant?
No. Imported readings are stored locally on your device. The app does not upload them to a Weight Track Assistant server. See the privacy page.
