How to connect your Withings scale to Gyroscope
Connect your Withings account directly so each supported weigh-in can join your food, activity, sleep, and health timeline.
Withings has a live direct integration, and its scales center on the weight and body composition signals used in a combined dashboard.
Applies to: See the current Withings scale lineup in What syncs below.
Short answer
Gyroscope has a direct Withings integration. Connect it once and your data joins everything else on one timeline, deduplicated against your primary device. Install your scale in the Withings App with the maker's documented device flow, then add Withings in Gyroscope.
What syncs
The current lineup and model differences come from Withings' official scale collection and comparison pages. Regional availability can differ.
Current scale lineup
| Model | Maker-documented focus |
|---|---|
| Body Smart | Weight, advanced body composition, standing heart rate, visceral fat, and BMI. |
| Body Comp | Advanced body composition, standing heart rate, vascular age, and electrodermal activity. |
| BodyFit | Full-body mapping and segmental body composition with a handle. |
| Body Scan | Segmental body composition, standing heart rate, vascular age, ECG, and electrodermal activity. |
| BodyScan 2 | Complete segmental body composition with Withings' current high-end biomarker set. |
Data from a weigh-in
Rows show what the scale family tracks, not a guarantee that every field is carried by the direct integration. Withings' Apple Health FAQ verifies the optional Health writes.
| Data | Reaches Gyroscope via | Notes |
|---|---|---|
| Weight | Direct Withings integration; also Apple Health | Supported across the current scale family. |
| Body fat percentage | Direct Withings integration; also Apple Health | Withings lists body fat percentage among its Apple Health writes. |
| Body mass index | Direct Withings integration; also Apple Health | BMI is included in Withings' Apple Health list. |
| Muscle mass | Direct Withings integration | Measured by composition models, but not listed in Withings' Apple Health export. |
| Bone mass | Direct Withings integration | Measured by composition models, but not listed for Apple Health. |
| Body water | Direct Withings integration | Measured by composition models, but not listed for Apple Health. |
| Visceral fat | Direct Withings integration | Available on current composition models, but not listed for Apple Health. |
| Standing heart rate | Direct Withings integration; also Apple Health | Available on supported models. Withings can write heart rate to Apple Health. |
| Model-specific scans | Direct Withings integration | ECG, vascular age, and electrodermal activity vary by model and are not promised as direct payload fields. |
The family shares weight as its foundation, while body composition and added assessments depend on the model. Withings' current scale comparison is the authority for those differences. A capability shown for Body Scan or BodyScan 2 should not be assumed for Body Smart, Body Comp, or BodyFit, which is why the lineup table comes before the data inventory.
Apple Health is optional rather than the recommended Gyroscope route. Withings' official FAQ lists supported write categories, while its troubleshooting guide explains that both apps may need to be opened and refreshed. The direct Withings connection remains the clean account path. The field rows describe maker-confirmed scale capabilities without exposing an unpublished direct payload.
Connect it
- Open the Withings App, open Devices, tap Add, choose Scales, and select your model. Withings documents this path in its current installation guide.
- Put the scale in setup mode, confirm the pairing code, and connect it to Wi-Fi or Bluetooth as the app directs.
- Take a test weigh-in and confirm that it appears in the Withings App.
- Open Gyroscope, add Withings as a data source, and complete the Withings account authorization.
What you get in Gyroscope
Supported Withings records can join activity, food, sleep, heart, and other sources on the same timeline. A connected scale is especially useful because it turns a recurring weigh-in into context for the rest of the day instead of a number left in a separate app.
Health Score includes a weight area alongside heart, sleep, activity, places, computer time, mind, and nutrition signals. Its area grades and accuracy rating show where your dashboard has strong coverage and where information is missing.
Gyroscope also tracks energy balance through TDEE and calorie surplus or deficit. That creates a direct comparison between weight trend and the food and activity signals already tracked over the same dates.
Insights to try
- Weight vs calorie surplus/deficit.
- Body fat vs workout frequency.
Consistent weigh-ins make the trend easier to compare. Gyroscope can evaluate correlation strength, timing lag, rolling windows, high-versus-low day differences, outliers, and a trendline. Use the same scale under similar measurement conditions when you want a cleaner long-term comparison. Repeat consistently.
Common questions
Should I use the direct integration or Apple Health?
Use the direct Withings integration as the primary connection. Apple Health is an optional secondary route for supported fields such as weight, body fat percentage, BMI, and heart rate.
Why is Apple Health not updating?
Withings says iOS may require both apps to be opened. Its troubleshooting guide recommends opening Withings in the foreground and refreshing the Home screen.
Do all Withings scales measure the same things?
No. All current models center on weight, but body composition and the added scan types vary. Use the lineup table and Withings' model page to confirm your scale's capabilities.
Does every model-specific biomarker reach Gyroscope?
No field-level direct payload is published. The page names maker-documented scale capabilities without promising that every model-specific scan transfers to Gyroscope.
