Anura

Anura™ is a general wellness app that uses your iPhone’s video camera to measure, track and record your resting heart rate and stress level based on the blood flow in your face. It uses Affective Intelligence to transform your iPhone into your personal health AI™.
Category Price Seller Device
Health & Fitness Free Nuralogix Corp. iPhone, iPad, iPod

Features and Benefits:
• Contactless – No sensors to touch. Measurements are taken just like a selfie!
• Quick – It requires only 5 seconds to start tracking your Heart Rate, and a comprehensive measurement takes only 30 seconds.
• Measure your resting heart rate and stress level. Our Anura Stress Index (ASI) can help you quantify and monitor your stress over time.
• A history of your measurements is saved, and you can share your results (should you choose) with your family, friends or doctor.
• Private – No images or video are saved on your device or transmitted as part of a measurement. 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.
• Use Anura™ often to increase your awareness of stress and general health.
• Completely free!

How Anura Works:
• 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.
• This information is contained in conventional videos.
• A technique known as Transdermal Optical Imaging (TOI™) is used to extract blood flow information from the video. This technique was developed by our team of neuroscience, psychology, physiology, signal processing and deep learning experts.
• Anura™ uses your phone’s video camera to extract and send encrypted blood flow information (no video or photo) to the cloud to be processed by our DeepAffex™ Affective Intelligence engine.
• DeepAffex™ applies advanced signal processing and AI models to predict your resting heart rate and stress, then sends these results back to Anura.


How the Anura Stress Index (ASI) was Developed:
• We began by taking continuous heart rate measurements of a large sample using traditional, contact-based methods (e.g. EKG). We then used this data to generate 3-D models of stress to derive a ground truth measure of stress using three dimensions.
• Using TOI™ signals, we obtain heart rate variability (HRV) measures based on time domain, frequency domain, statistical, dynamic systems, and nonlinear methods extracting over 20 features.
• By applying advanced machine learning techniques and other statistical methods, we maximized the correspondence between the more than 20 features extracted from the 30 second TOI™ signal and the ground truth.
• We then computed the statistical means and standard deviations of the predicted stress values to create a norm based on a Gaussian distribution.
• Finally, we converted the predicted stress values into a stress index with 5 levels where 1 is the lowest and 5 is the highest. The difference between each level represents one standard deviation.

I love it,, It is an effective and very useful App


Great app and functional

Great app game changer need to add more features and possibly integrate with Apple Watch and get glucose diabetes reading.


Great

It is the future you will be the doctor of your own.


Great idea but not useful now
Cory1967

Super idea I give them credit, but the technology just is not there yet. I tested this many times and tested my measures also with reliable machines, and the app is way off. Beyond being a toy there is no value if the data is consistently inaccurate. Also, the required light you need on your face is very hard to achieve. The frustration of dealing with that alone will raise your heart rate and blood pressure by the time you start the test, but anyway that doesn’t matter since the readings are so inaccurate. Maybe someday


Well worth it!

I was looking for an app that took blood pressure, not just monitored it via manual input. I read about this app and read and read and read!! How it measures, what exactly it can tell; each article increased my curiosity and excitement! It sounded like something I could at least try. I have mild high blood pressure and try to keep track but find with my busy schedule I often forget. I’ve been working with this for about 2 weeks...comparing outside b p monitor readings with this app. I’ve found the numbers to be very similar... within 4-6 points systolic and 5-8 diastolic. This is wonderful. I’m so glad I tried it. Currently the app is free; hopefully it will continue to be. I just love how I’m able to even monitor my stress level. Thank you for working to provide this service. .


I’m amazed

I’m am amazed how this app can be so accurate


Fun game

Read all vital signs off a photo and showed a perfect health status;)


Connection to Apple Health

As the other reviewer said, promising. Needs connection to Apple Health.


3 stars only because of unfixed bugs

The app is great and the science behind it is sound. However, the usefulness of the app is realized over time by being able to refer to your history. The history functionality is not working on iPhone 12 Pro Max. The selector does not allow you to choose anything other than heart rate history. The drop down menu does not drop down at all. I submitted a support request on the website >3 weeks ago and the issue has still not been resolved.
