FAQ

How can Sleep Analyzer help me understand my nights?

Discreetly placed under your mattress, Sleep Analyzer provides a medical-grade analysis of your night without any constraints. It monitors your sleep cycles, heart rate, and breathing patterns to detect potential issues like sleep apnea. This continuous tracking gives you and your doctor the professional insights needed to improve your long-term sleep quality.
Does the Sleep Analyzer work with all types of bedding?

We have engineered this technology to integrate seamlessly into almost any bedroom. The sensor remains highly accurate whether you use a spring, foam, or latex mattress. Only waterbeds and air mattresses are not compatible. Once installed, it operates with total discretion, transforming every night into a comprehensive health report.
Will my data be affected if I share my bed with a partner?

No. Sleep Analyzer is engineered to focus exclusively on the person resting directly above it. It filters out the movements or heart rate of a partner, ensuring that the data captured is yours alone. Your results are then securely synced via Wi-Fi to your Withings account.
Do I need a subscription to track my sleep quality?

No, you'll always have free, unlimited access to your sleep history and trends in the Withings app. Withings+ is an optional premium service that provides deeper analysis and expert-led guidance to help you optimize your health trajectory. An introductory one-month trial is available when you select the subscription option at purchase, allowing for a full evaluation before billing begins. View subscription details here.

*Sleep Analyzer is not intended to be used with water mattresses.
