Vessel age:

Depending on genetics and lifestyle, arteries can age at different rates. Based on years of research, Withings' algorithm assesses the age of your arteries to give you an accurate picture of your cardiovascular health. The algorithm measures pulse wave velocity (PWV) and compares this with PWV measurement norms for people of corresponding ages and, in combination with the physical characteristics, creates an analysis that provides information about your vascular age. This is valuable data because your vascular age could reveal a higher risk of developing a vascular disease later in life.

Body composition:

  • Muscle mass
  • Body fat:

Excess fat can be a risk factor for heart disease, so it's important to keep track of.

  • Percentage of water in the body:

Stay hydrated by tracking your water percentage!

  • Bone mass:

Long-term changes in bone mass can indicate diseases that can be detected with regular monitoring.

BIA method (bioelectrical impedance analysis)

Your body composition is determined using an imperceptible current detected via sophisticated sensors. The scale generates precise calculations using algorithms.

  • Individualised health insights
  • Compatible with 100+ apps

Your data such as weight and body composition can be synchronised with +100 favourite apps & fitness programs.

Technology you can trust:

Thanks to years of experience, user feedback and modern research, the scale impresses with exceptional reliability, user-friendliness, and durability.

  • Very precise

Thanks to the patented Position Control™ technology, the scale recognises if you aren't standing correctly, ensuring the best read of your data.

  • Ideal for multiple users:

The intelligent scale recognises and documents the data of up to 8 individual users.

  • Predictive weighing

Whenever you weigh in, check the local weather forecast on the scale display (via Wi-Fi) and the number of steps you have taken in the past few days (if you are using a tracker or have activated the step counting function in the app).

  • Long-lasting:

Enjoy 12 months of battery-free operation before you need to recharge it

  • Automatic smartphone synchronisation:

After each use, the data is synchronised with the free Withings app (iOS and Android) via Wi-Fi. Your smartphone does not need to be near the scale to sync. You can view your weight, body composition and heart rate history in the app.
