SmartScaleSync is a 3rd party tool and is not affiliated with the apps listed below. The connections SmartScaleSync makes with fitness platforms may fail or be discontinued as those platforms change their systems over time. These changes are outside our control, and while we will do our best to restore service, we cannot guarantee success.
| Scale | What syncs | Notes |
|---|---|---|
| Eufy | What syncs: Weight, body fat, BMI, muscle mass, bone mass, water %, visceral fat, basal metabolic rate, metabolic age | Our Eufy connection works with the EufyLife app; the newer Anker Eufy app is not supported yet. |
| Fitbit (ending soon) | What syncs: Weight, body fat, BMI | Google announced it would shut down the Fitbit API in September 2026, so this could happen any day now. We're looking into whether we can add support for the Google Health API as a replacement, but we're not yet sure it will be feasible. More details on the shutdown from RunGap's creator: RIP Fitbit integration (r/RunGap). |
| Hume | What syncs: Weight, body fat, BMI, muscle mass, bone mass, water %, visceral fat, basal metabolic rate, metabolic age | |
| Renpho | What syncs: Weight, body fat, BMI, muscle mass, bone mass, water %, visceral fat, basal metabolic rate, metabolic age | The Renpho app only allows one active session at a time, so you will need to log in to the Renpho app more often; ticking “Remember password” on its login screen saves time. |
| Tanita | What syncs: Weight, body fat, BMI, muscle mass, bone mass, water %, visceral fat, basal metabolic rate, metabolic age, physique rating | Our Tanita connection works with the MyTANITA app; Health Planet and Healthy Edge are not supported yet. |
| Withings | What syncs: Weight, body fat, BMI, muscle mass, bone mass, water %, visceral fat, blood pressure | Weigh-ins must come from a Withings (or Nokia) scale; the Withings API only shares data recorded by a Withings (or Nokia) scale. |
| Wyze | What syncs: Weight, body fat, BMI, muscle mass, bone mass, water %, visceral fat, metabolic age, physique rating | Our Wyze connection needs a Wyze API key (how to create one) and checks for new weigh-ins every 15 minutes. |
| Xiaomi* | What syncs: Weight, body fat, BMI, muscle mass, bone mass, water %, visceral fat, basal metabolic rate, metabolic age | *Our Xiaomi connection is in beta and works with the Mi Fitness app; Xiaomi Home is not supported yet. |
| Manual Entry | What syncs: Weight, body fat, BMI, muscle mass, bone mass, water %, visceral fat, metabolic age, physique rating | Enter a weigh-in on our support page and it is uploaded to your connected destinations. |
