Your resting heart rate is a strong indicator of your general and cardiovascular health, however, measuring your RHR requires very specific measurement conditions. As such, we use HR as an easier alternative and make provision for some differences in how we interpret an "acceptable" result. For instance, variables such as your gender and fitness level will influence what is deemed "acceptable" and because you might not be fully at rest while doing a mobile measurement, "normal" can also be slightly higher.

If you are a male and your heart rate measures from 45 to 85, your Kimi Screening results will show as "acceptable".

If you are a female and your heart rate measures from 50 to 90, your Kimi Screening results will show as "acceptable".

This is an approximate measure to check if you are over or underweight. It's calculated by dividing your weight in kilograms by the square of your height in metres. Any BMI measurement of 18 and lower, or 30 and higher we flag as "be aware".

These are the clinical BMI guidelines:

• < 18.5 = Underweight
• 18.5 to 24.9 = Normal
• 25 to 29.9 = Overweight
• 30 to 34.9 = Class I obesity
• 35 to 39.9 = Class II obesity
• ≥ 40 = Class III obesity

VO2 max is one of the most used fitness metrics, used to describe your cardiorespiratory fitness. It looks at how much oxygen your body can take in and deliver to your muscles.

To get a very accurate measure, you would need to wear an oxygen mask and do a treadmill test until you reach maximal physical exhaustion, however, various studies have shown that there are accurate non-exercise estimates of VO2 max. Read more.

We use a non-exercise estimate of VO2 max to calculate your estimated fitness level. Your resting heart rate, age, gender and BMI (body mass index) are used for this calculation. To simplify your results, we display a fitness level. Our result categories are based on the Fitness Registry and Importance of Exercise Database (FRIEND).

Cardiorespiratory fitness (CRF) powerfully predicts outcomes across health and disease. Low CRF is associated with a 2 to 5-fold increase in cardiovascular disease (CVD) or all-cause mortality independent of other CVD risk factors.

These numbers should be used as a guide only. A single blood pressure measurement that is higher than normal is not necessarily an indication of a problem. Your doctor will want to see multiple blood pressure measurements over several days or weeks before making a diagnosis of high blood pressure and advising on treatment.

Blood pressure changes in response to different activities. It is therefore recommended to be measured while at rest. Consistently high blood pressure readings may result in a diagnosis of high blood pressure (hypertension), which poses a higher risk for health problems such as heart disease, heart attack, and stroke. In most cases, high blood pressure has no defined cause, and it is called primary hypertension. However, it is related to unhealthy lifestyles such as physical inactivity, stressful life, obesity, shift work, pregnancy, etc. It should be emphasised that Blood Pressure can be managed through diagnosis, lifestyle changes, medication and long-term monitoring.

We classify blood pressure according to the tables below:

Does the screening app give a measure of the systolic and diastolic readings at that specific point only or can it also tell if someone is hypertensive or just experiencing a surge in readings?

The screening app takes a point-in-time measurement. So, any temporary surge due to high stress levels or fatigue (as an example) will cause high blood pressure readings to reflect in the results. It is thus advisable for insured lives to be calm and relaxed during a screening session.

This is the number of breaths you take per minute. Respiration rates may increase should you present with a fever, underlying illness or other medical conditions. Asthma, anxiety, pneumonia, congestive heart failure, lung disease, the use of narcotics or a drug overdose are some of the conditions that can change a normal respiratory rate.

The normal respiration rate for an adult at rest is 12 to 20 breaths per minute.

A respiration rate under 12 or over 25 breaths per minute, while resting, is considered abnormal.

Note: Although above 20 is considered above normal ranges we only indicate "Be Aware" if respiration is above 25 breaths per minute.

Respiratory rate is a well-documented indicator of serious illness, for more on ranges and conditions, read "Respiratory rate: the neglected vital sign" Michelle A. Cretikos, Rinaldo Bellomo, Ken Hillman, Jack Chen, Simon Finfer and Arthas Flabouris

We measure your Heart Rate Variability HRV). HRV measures the Autonomic Nervous System (ANS). The ANS is tied to every automatic process in the body and comprises of two main branches that control the body's stress and recovery processes. It regulates blood sugar, body temperature, blood pressure, sweat, digestion, and much more.

HRV also links cardiovascular activity to the respiratory system, digestive system, and other recovery and stress-related systems. We use HRV to determine stress and show this to you as a mental stress index. This index is based on Baevsky's mental stress index with levels of low, normal, mild, high and extremely high.

Bear in mind … You may feel stressed but get a good result on Kimi Screening. This means that your body (and heart) is coping well with your current level of stress. The opposite could also be true – you may not feel stressed and get a bad result which means you think you can hide it, but your body (and heart) is telling a different story. That's when Kimi will put you in touch with a doctor or wellness coach.

The Kimi Screening app is specifically for new and existing Momentum Group clients who want to complete a digital health check-up as part of their wellness screening for health and life insurance purposes.

As a Momentum Group client, your life insurance application and/or medical scheme benefit qualifies you to receive a voucher code to redeem your allocated number of screenings.

A session voucher allows for multiple screenings but is limited to a 9-minute session. You can purchase additional sessions in the app for R19.99 per session.

Kimi Screening has not been tested on minors and is not to be used on anyone younger than 18 years of age.

As an insurance applicant, you will receive a (URL) link. When you click on the link (from your smartphone), it will navigate you to the app store and prompt you to install the Kimi Screening app.

Then, follow these steps:

1. Step 1: Download and open the Kimi Screening app on your smartphone.
2. Step 2: Click "I have a voucher code".
3. Step 3: Register as a new user.
4. Step 4: Go to your email, from your phone, and click on the voucher link.

Know your voucher code? In the app, type in the last 8 digits of the voucher code.

Once you have activated the voucher, you'll have 9 minutes to complete the screening before the session expires. Only one measurement is required, but you can do as many as you like within the 9 minutes.

NOTE that the results from your first successful screening will be sent through to Momentum.

Multiple insured lives, multiple phones: It's important to note that if you have two or more people who are screening for insurance purposes, each insurance applicant must download the Kimi Screening app and register their own profile.

Using one smartphone for all: If you have two or more people that will be screening from the same phone for insurance purposes you can follow this process:

1. * Download the Kimi Screening app on your smartphone.
2. * 1st insurance applicant registers as a new user and creates his/her profile.
3. * Do your screening.
4. * 1st insurance applicant must then log out of the app.
5. * 2nd insurance applicant can now open the app, register as a new user, and create his/her profile.
6. * Do your screening.
7. * Follow this process for each additional insurance applicant.

With a single screening, Kimi checks your heart rate, respiration, blood pressure, your body's ability to handle stress and your estimated level of fitness.

Kimi also records any medication you may be taking, your smoking status, and alcohol consumption and calculates your BMI (Body Mass Index) using your height and weight.

HEART RATE: Your resting heart rate is a strong indicator of your general and cardiovascular health, however measuring your RHR requires very specific measurement conditions. As such, we use HR as an easier alternative and make provision for some differences in how we interpret an "acceptable" result.

RESPIRATION: This is the number of breaths you take per minute. Your respiration rate may increase should you present with a fever, underlying illness or other medical conditions.

BLOOD PRESSURE: Blood pressure is the force exerted by circulating blood against the walls of your blood vessels. Systolic blood pressure is a measure of this pressure as your heart contracts, while diastolic is a measure of pressure as it relaxes. Too much pressure causes damage to the blood vessels, as well as to some of the organs that they supply. The higher your blood pressure, and the longer it stays uncontrolled, the greater the damage it can cause.

STRESS: Where heart rate measures the number of beats per minute, your HRV (Heart Rate Variability) measures the changes in time (or variability) between successive heartbeats. This is important because your HRV reflects your body's physical ability to handle stress. If we cannot measure HRV, you will answer 2 stress-related questions.

FITNESS: We use a non-exercise estimate of VO2 max to calculate your estimated fitness level. Your resting heart rate, age, gender and BMI (body mass index) are used for this calculation.

Once a screening is complete you will get results for heart rate, respiration, blood pressure, stress level and your estimated fitness level.

Your blood pressure fluctuates throughout the day. Your reading can also fluctuate with up to 20 points in both traditional (BP cuff) and digital BP measurements. Exercise, stress, smoking, alcohol, caffeine, body temperature and even a full bladder are all factors that can affect your blood pressure.

Environmental factors such as light, movement and the distance from your fact to your phone during the screening also impact your results.

For Kimi to get a measurement, follow these guidelines:

1. - should be in a FIXED POSITION throughout the measuring time.
2. - should be HELD IN YOUR HAND.
3. - close other applications and browser tabs that are working in the background.
4. - don’t use the phone’s camera for other apps, like video, while measuring.

1. - each measurement is for ONE PERSON ONLY.
2. - you should BE SEATED and at rest during the measurement.
3. - hold the phone WITHIN 20-30 CM from your face.
4. - your face must be fully exposed, so no caps or sunglasses.
5. - there shouldn’t be a light source behind you and no direct sunlight; NATURAL LIGHT is best; Avoid any shadows or glare.
6. - the lighting shouldn’t change during your measurement.

1. - Do the test in the morning, but before caffeine, any exercise or your first email.
2. - If you smoke OR vape, wait at least 60 minutes after your last puff before doing the test.
3. - Make sure you have been sitting quietly for a few minutes.
4. - Don’t talk while doing the test and avoid any multitasking.
5. - Wait a day or 2 to do the test if you:
6. * Consumed alcohol the night before.
7. * Have performed any strenuous physical activity in the past 24hrs.
8. * If you’ve slept poorly, feel sick, stressed, rushed or short on time.
9. * Have distractions around you.
10. * Have been driving or just come home from work.
11. - If you’re pregnant your results won’t be a true reflection of your health.

Movement:

1. * Sit at a table and rest your arms on the surface while holding your phone to keep it steady.
2. * Ensure no people or moving objects are in the background.
3. * If possible, try a different phone, as some devices process movement more sensitively than others.

Tilted head:

1. * Hold your phone at eye level with the selfie camera parallel to your face.
2. * Maintain a distance of 20-30 cm between your face and the device.

Uneven lighting:

1. * Choose natural light and avoid LED or fluorescent lights.
2. * Utilise a single light source that illuminates your entire face, avoiding direct sunlight or shadows.
3. * The light source should not be directed towards the camera.
4. * Avoid any glare on your face or phone, including those on your glasses.

To receive a result you’ll need to complete verification, some health-related questions and the full measurement, which takes 1½ minutes. The complete process on average takes between 3-5 minutes.

Basically, you need to have a smartphone with a camera, but it does get technical.  We’ll check this when you start your screening, so don’t worry too much about the details. Here are the requirements:

1. * Integrated camera with minimum VGA resolution (640x480).
2. * 3GB ram.
3. * Video camera with minimum 30 FPS.

For Android, the minimum supported browser is Chrome version 113 or the latest versions of Samsung browser, Opera or Edge.

For iPhone:

1. * iPhone 12 and newer.
2. * Minimum supported browser: iOS/Safari version 17, Chrome version 113.

Remote photoplethysmographic imaging (rPPG) is the technology used. rPPG imaging is a camera-based solution that enables stress and heart rate monitoring by using regions on the face. We measure heart rate and stress level by reconstructing the rPPG signal from the smartphone camera using signal processing. The measured vital signs are not intended for medical use, including self-diagnosis or consultation with a doctor, and are only designed for general fitness and wellness purposes.

The screening technology has been thoroughly tested and the results validated against trusted methods. The digital screening has been approved by SAHPRA (South African Health Products Regulatory Authority) as a medical device and meets clinical accuracy requirements for a class B cardiovascular diagnostic tool. Accurate results are dependent on following the required instructions carefully.

Both tests measure the vital signs at rest. An active assessment includes a 5-minute step test to measure your VO2 max.

Yes, you can. Your metrics fluctuate quite a bit for good reasons. Make sure you are well rested, relaxed and in the right place to screen.

1. * Things like exercise, stress, smoking, alcohol, caffeine, body temperature and even a full bladder can impact your blood pressure.
2. * Your environment can also impact your result, with light, movement and the distance of your phone from your face during the screening all playing a role.

When any of your results are outside the ranges for a healthy individual, clients can expect to be contacted by a medical professional from Hello Doctor. They can choose to discuss their results with the doctor, and the doctor can make recommendations. Hello Doctor forms part of Momentum Group and client data will not be shared with other parties that clients have not consented to.

First, you’ll do a liveness check, and a 3D image of your face becomes your “password” to securely access our systems. We use the Department of Home Affairs data to validate information of the user. This will happen automatically in the background for most clients, while others may be requested to scan their Green barcoded ID book, ID Card or passport with their smartphone before they do their screening. Throughout the screening process we will check that the same user is doing the screening.
