The description of Anura

Anura™ is an AI-based application that uses the camera on your mobile phone to measure your general wellness. By taking a 30-second video selfie, Anura™ provides a variety of physiological and psychological results including:
• Heart rate
• Irregular heartbeats
• Respiration rate
• Blood pressure (systolic and diastolic)
• Heart rate variability
• Cardiac workload
• Stress index
• Cardiovascular disease risks
Anura™ is the world’s first app allowing for contactless blood pressure measurement with only a 30-second video selfie. According to the American Heart Association (, many people with high blood pressure are not aware of their hypertensive condition. The computational models used by Anura™ were developed using medical-grade equipment and scientific instruments found in labs and clinics. The accuracy of Anura™ measurements has been tested and validated at both NuraLogix, the developer of Anura™, and university labs.
Anura’s Features and Benefits:
• Contactless – No sensors, contacts, or cuff to touch. Measurements are taken just like a selfie!
• Quick – It requires only 5 seconds to start measuring your heart rate, and a comprehensive measurement takes only 30 seconds.
• Private – Your blood flow information is encrypted when sent to our cloud servers for analysis and your measurement history is stored using the same encryption techniques that are used by banks. Your video images are never saved while performing a measurement.
• Use Anura™ often to increase your awareness of stress and general wellness.
• Free – Most importantly, Anura is completely free to use!
The underlying science:
• Human skin is translucent. Light and its respective wavelengths are reflected at different layers below the skin and can be used to reveal blood flow information in the human face.
• Our Transdermal Optical Imaging (TOI™) technology extracts this information and sends it securely up to the cloud to be processed by DeepAffex™, our cloud-based Affective AI engine.
• Cardiovascular disease risk, heart attack risk, and stroke risk are calculated upon the Framingham Method and derived from an algorithm developed based on data from prospective studies that followed up with participants in terms of their cardiovascular health for over ten years.

Don’t forget that Anura is not a substitute for the clinical judgment of a health care professional. Anura is intended to improve your awareness of general wellness. Anura does not diagnose, treat, mitigate or prevent any disease, symptom, disorder, or abnormal physical state. Consult with a health care professional or emergency services if you believe you may have a medical issue.
Anura™ works best with devices supporting the Android ‘Camera2’ API on Android 9 or later.
