Samsung and Withings have announced a partnership that lets Galaxy Watch data and Withings health data move between their apps. Samsung Health can pull in weight, body fat percentage and BMI from Withings devices, while Galaxy Watch step data can show up inside the Withings app.
What is actually new
The public announcement is mainly about bringing more attention to a connection that sits on top of Android’s existing Health Connect setup. Samsung Health has supported Health Connect for a while, and Withings already had Android support paths for sharing data with other health apps.
The difference now is that Samsung and Withings are promoting the link directly. Samsung is also attaching a US offer to it, with eligible Galaxy Watch buyers able to receive a Withings Body Smart scale.
But make no mistake. This is not a full merger of every Samsung and Withings health metric. It is a targeted sync around activity and body measurements.
Why this is useful
The obvious pairing is Galaxy Watch plus a Withings scale. The watch tracks steps through the day, while the scale adds weight and body composition readings at home. The French outfit has the best smart scales on the market.
There are limits, though. Heart rate and sleep are both supported by Samsung Health and Health Connect at a technical level, but the public Samsung and Withings material does not confirm that those metrics are part of this new cross-sync. The same goes for blood pressure, even though Withings sells blood pressure monitors and Health Connect supports blood pressure records.
Health Connect is doing the quiet work
The likely flow is not Galaxy Watch talking directly to the Withings app. It is more likely Galaxy Watch data moving into Samsung Health on the phone, then through Health Connect, then into Withings. Withings data follows the same kind of route back toward Samsung Health.
That is useful because Health Connect gives Android users a central place to manage permissions. It also means users can choose which apps can read or write certain health records, instead of handing over everything at once.
There is still some friction. Users need the right app versions, Health Connect permissions need to be enabled and older Android phones may require the separate Health Connect app. Watch data may also depend on when the Galaxy Watch syncs back to the phone.
Why Samsung and Withings both want it
For Samsung, the partnership makes Samsung Health look more complete without the company having to build every health device itself. Galaxy Watch already gives the company daily activity data, but a scale is still the better tool for weight and body composition trends.
For Withings, the benefit is access to Samsung’s smartwatch audience. If Galaxy Watch step data can feed into the Withings app, the app becomes more useful to people who may own a Withings scale but wear a Samsung watch.
There is also a service angle here. Both companies benefit if users keep returning to their health apps, checking trends and connecting more devices. That can support longer-term engagement and, potentially, paid health features around the data.
