The Vitalist Health Band provides estimates and measurements to support your everyday health awareness. Like other wearable devices, it may sometimes show a reading that does not match how you feel.

Your well-being comes first. Do not ignore how you feel because of a reading from the band.

Why might a reading be different?

Readings can be affected by several factors, including:

• Movement or physical activity.

• A loose or incorrectly positioned band.

• Dirty sensors or skin between the sensors and your wrist.

• Cold hands or reduced blood flow.

• Tattoos or darker skin beneath the sensor area.

• Wrist movement or bending, especially during certain activities.

• Other conditions that affect how well the sensors can collect information.

For example, blood oxygen (SpO₂) readings are generally collected when you have been very still for at least five minutes. If you are moving, talking, or travelling in a vehicle, a reading may be delayed or unavailable.

What should I do?

• Check that the band is positioned correctly and comfortably.

• Make sure the sensors on the underside of the band are clean and touching your skin.

• Allow time for the app to sync and refresh.

• If you have questions about a reading, contact your care team.

Vitalist Support can help with technical issues, such as missing readings or syncing problems, but cannot interpret readings or advise you about your health.

Important: Do not change medication or treatment based only on readings from the band. If you feel unwell, contact your care team or seek medical help as appropriate. If you are experiencing a medical emergency, call 911.
