Withings is known for design and innovation in connected devices, such as the first Wi-Fi scale on the market (introduced in 2009), an FDA-cleared blood pressure monitor, a smart sleep system, and a line of automatic activity tracking watches.

[5] Withings was founded in 2008 by three executives from the technology and telecom industries: Éric Carreel (CEO), who was co-founder of Inventel; Cédric Hutchings; and Fred Potter.

[7] In January 2011, Withings announced at the Consumer Electronics Show in Las Vegas that its second product would be a blood pressure monitor that connects to the iPhone.

[8] It also announced it would produce a baby monitor for use with smartphones and other connected devices, which was made available to purchase across Europe in November 2011 and in the United States in February 2012.

The compatibility across Withings' range of connected devices enabled the integration of personal data into the iOS Health app.

[19] On May 2, 2018, Nokia announced plans to sell its health tech business to Withings co-founder Éric Carreel.

[24] Withings acquired both device company Impeto Medical as well as the personalized fitness and meal planning app 8fit in 2022.

[32] It is a hybrid[33] and provides heart rate monitoring, GPS tracking, and fitness level analytics including oxygen intake sensors.

[35][36] The ScanWatch is a smartwatch that incorporates a sensor that measures the oxygen saturation level in the blood to identify sleep apnea and detects atrial fibrillation.

It measures weight and fat mass and sends data to the user's app over Wi-Fi,[39] and also connects to platforms such as Google Health[40] and Microsoft HealthVault[41] as well as diet and exercise sites such as DailyBurn.

[51] The BPM Core, introduced in 2019, adds an ECG function and a digital stethoscope which listens for some heart valve defects.

[52] Withings Thermo is a temporal artery thermometer which uses a 16-sensor array to deliver fast and accurate temperature readings.

Its Wi-Fi and Bluetooth connectivity allows smartphone users to log readings, along with other information such as symptoms and medication.

The device is placed in a toilet and allows for daily urine tests, with results reported to the user electronically.

[59] Since 2023, Withings has allowed American Diabetes Association members to have free access to smart scale data and live coaching through its database.
