The iHeart system is the health and wellness tool to calculate your Internal Age, a measure of how supple you are on the inside. How supple—or how stiff—you are inside gives you a snapshot of your current heart health and lets you track the effects of lifestyle choices on your Internal Age.
The iHeart system consists of:
- The iHeart Device
- The iHeart Internal Age app
- Recordings, calculations, and analyses of your Internal Age readings kept secure and available on your personal iHeart data webpage at goiheart.com
While the iHeart system shows you overall health trends and enables wellness tracking, it is not a medical device. Do not use any component of the iHeart system to diagnose or manage any medical condition.
To log into your dashboard you must register your iheart device on your iheart internal age, or iheart internal ago Pro app. To do so, go to your app home screen and press the gear/settings icon in the bottom right corner of the screen. A window will pop up, press ‘Register Device’. You will register with your email and a password. Once you have completed the registration process you can log into your online dashboard.
The iHeart device is a fingertip pulse reader that detects and records arterial pulsations in your finger. The sampling rate of the iHeart device is so high that it can detect distinct waves of blood coming from the heart, travelling down the aorta and reflecting back. The iHeart device transmits these recording to your iPad or iPhone, where the iHeart app translates them into a pulse wave for analysis and display. After 30 seconds, you’ll have immediate results: Internal Age and Aortic Stiffness reading.
The iHeart device measures real-time heart rate and blood oxygen levels. The amount of oxygen in your blood indicates the overall efficiency of your respiratory system.
iHeart device readings are intended to be used only for fitness and educational purposes.
The iHeart device is not intended to be used for treatment of any medical illness.
The iHeart device is not a medical device. Do not use the iHeart system to diagnose or manage any medical condition.
The iHeart device connects to your iPhone or iPad via Bluetooth. Please make sure that your bluetooth is turned on before beginning an iHeart recording. If you continue to experience difficulty please contact email@example.com
Press the white button once. You have 10 seconds to slip it onto your finger before it shuts off.
We recommend that you use your first or middle finger. It doesn’t matter which hand you use, just make sure your hands are warm! If you have poor circulation or cold hands rub them together for 30-seconds before testing.
This feature enables you to read the display no matter which hand you test with
To flip the display right-side up, press the white button once.
When the iHeart device senses that no finger has been in it for 10 seconds, it turns itself off. This action saves battery power.
To turn on the iHeart device, slip it on a finger and press the white button once.
Other oximeters measure only heart rate and blood oxygen saturation. The iHeart device also measures Aortic Pulse Wave Velocity to assess the flexibility of the aorta, the largest artery in your body. How flexible your aorta is reflects the physical effects of your healthy—and maybe not-so healthy—behaviors and choices. This measure forms the basis for determining your Internal Age.
To register your device open you iHeart Internal Age app and it the gear button in the bottom right side of the screen, a pop up will show like below. Press ‘Register’ and you will have registered your iHeart Device!
The iheart device has a $195 price point, which can be high for families. You must understand that iheart is not a novelty product, it is a science based health monitoring device that has taken many years to develop and is run by a family business. We are always looking for ways to improve the iheart product and hope to release a less expensive version in the future.
The benefits of walking are well known in medical research journals. In fact, walking 30 minutes daily can normalize blood pressure, reverse Diabetes, improve sleep, reduce risk of Dementia, relieve symptoms of anxiety and depression and lead to a longer and healthier life. None of this is in doubt. The question is why, with such clear evidence, are physicians prescribing so many pills rather than leading crowds on early morning hikes.
Physicians are primarily focused on treating illness, not the maintenance of health. It is difficult for doctors to offer patients an overall assessment of health and a simple way to see health improving with walking and other positive lifestyle choices.
iHeart uses a fingertip pulse sensor, a 30 second test and a mobile app to provide an indication of overall health. iHeart measures Aortic Stiffness, accepted by medical scientists to predict risk of death from all causes. Aortic Stiffness is linked to stiffness of the spinal column, internal organ function and circulation of cerebrospinal fluid to the brain. Aortic Stiffness is known to predict risk of heart disease and dementia later in life for individuals in their 30’s.
Aortic Stiffness improved with exercise (including walking), a diet rich in omega-3 fatty acids and stress reduction. iHeart is intended to guide people to make healthy lifestyle choices in order to feel better and live longer.
iHeart Internal Age App
iHeart is currently only available on iPhone 4S and newer generations, as well as iPad 3rd Gen and up. Android is currently being developed and will be available in Spring 2017.
The iHeart device uses Bluetooth Low Energy (4.0) to connect to your smartphone/tablet and is compatible with iPhone 4S and newer models, and iPad 3rd Generation and newer models.
The iHeart Internal Age test takes 30 seconds with immediate results.
Variations in Internal Age can be due to a number of factors. To attain the most consistent readings make sure you test yourself at the same time each day, when relaxed, while sitting down and not moving your hand. Variations are very normal, and are related to changes in blood pressure. This is why it is important to see the trend of your Internal Age/Aortic Pulse Wave Velocity numbers over time.
Factors that will affect readings:
Movement will cause inconsistent readings. You can tell that your readings are off if there are spikes in the pulse shape and it does not look consistent.
Food and Drink - Food and drinks affect readings, which is why we suggest testing in the morning before your body has taken in any food or drink.
Caffeine - Coffee and caffeinated teas have negative effects on iHeart readings on the short term and long term. To attain a steady baseline, test before ingesting coffee or caffeinated tea.
Irregular Heartbeat - An irregular heartbeat will have an effect on iHeart readings. You will be able to see if your heart rate is irregular by watching the pulse stream across the screen during testing. The space between each beat should be the same throughout the entire test. If you see it shortening and lengthening, the heartbeat is irregular. If your heartbeat is irregular once every 15 seconds, the iHeart system will be able to pick it up and give you a good reading. If your heartbeat is irregular every few seconds, you will want to save that test and show it to your doctor for review.
- Relax and allow your body to settle for one or two minutes before an iHeart recording.
- Sit still, comfortable, and relaxed for entire 30-second recording.
- Don’t talk or move during the recording.
- Slip your first or middle finger fully into the iHeart oximeter.
- Ensure the finger used is warm and dry.
- Place the hand used in the recording flat on level surface, like a table top or your leg.
Beneficial influences include:
- Increased daily movement
- Increased daily laughter
- Healthy dietary choices, including consuming foods with Omega-3 fatty acids
- Not smoking
- Consistent and adequate hydration with clean water and/or green tea
- Quiet relaxation
- Peaceful meditation
- Supportive social relationships
Detrimental influences include:
- Too little daily activity
- Not enough laughter in your life
- Poor dietary choices, including over-indulgence of processed foods, refined flours and sugars, unhealthy fats, and alcohol
- Consistent inadequate hydration
- Recurring and unresolved stress
- Few nurturing relationships
You can record your pulse wave as often as you like, but it is most effective to record yourself at the same time each day.
Note: You will likely see a significant drop in Internal Age after exercise. Exercise is known to lower blood pressure, which decreases Aortic Pulse Wave Velocity, reducing your Internal Age measurement. That’s not a bad thing, but where you will gain the most insight on how your outer behaviour affects your inner health is by tracking your Internal Age over time and matching changes in those data with changes in your life.
The iHeart Internal Age app collects and analyzes data from the iHeart device to create a pulse wave display and to calculate your Internal Age. It can also show you whether you are growing older or getting younger inside, based on your current and previous iHeart recordings. This trending data, along with the personal notes you can add to an iHeart recording, can help you judge the consequences of different lifestyle choices.
The app is compatible with the iPad 3 (or later versions) and the iPhone 4S (or later versions), and uses Bluetooth(R) 4.0 technology.
If you look at the pulse shape in your iheart recording you can see a red dot. That red dot is the beginning of the Reflected Wave, which is a vital part of measuring aortic pulse wave velocity and Internal Age. When the heart beats, a wave of blood travels down the aorta very quickly. The aorta splits at the kidneys and the groin, when the blood meets these split points it creates a reflected wave travelling back toward the heart. If that reflected wave comes too early (due to a stiffer aorta and increased aortic pulse wave velocity) the reflected wave will meet the outgoing wave of blood still leaving the heart and create a crash of the two waves, overloading the heart and the blood vessels in the brain and extremities.
If you press the question mark on your app beside Aortic Pulse Wave Velocity you will see an animation showing the whole process of blood leaving the heart, the reflected wave and the varying speeds for different ages.
iHeart provides objective evidence that positive lifestyle choices improve Internal Age. Health and Wellness professionals such as naturopaths, doctors, nutritionists, personal trainers, health coaches, and yoga instructors have reached out in the past year to let us know that they would use iHeart in their practice. We took that info and created iHeart Pro, a separate app that is to be used by health and wellness professionals. Using the same iHeart device, the Professional download the Pro app on the Apple App Store, which comes with 500 user profiles, and detailed reports sent out to each client after their internal age test. Each user profile also comes with an online dashboard through the www.goiheart.com site. We are currently in beta with iHeart Pro and are offering the app for a download cost only, the monthly subscription model will be in place fall 2016.
For reports to be sent your iPhone or iPad has to be connected to wifi to send data to the iHeart cloud to then be sent back to your clients in the form of a report. Your iHeart device connects to the cloud (where your reports are stored) via WiFi. If you’d like for your reports to be sent from your iPhone immediately please click the settings gear icon on the bottom right of the app screen homepage.
Under server connectivity click both WiFi and 3G on.
Please exit your iHeart Pro app completely by pressing the home button of your iPhone or iPad quickly twice. You will see every app you have open across the screen. When you see your iHeart Pro app flick it up to close it completely. Now re-open your app. The app will begin the synchronizing process, pushing data to the server and sending out your client’s reports. You should see the words ‘synchronizing’ with a percentage in the top right corner of the screen. This will push your reports out.
If you continue to have issues please contact firstname.lastname@example.org
iHeart Pro is a separate piece of software used with the original iHeart device. iHeart Pro has been developed for health and wellness professionals to use with their clients to show objective evidence that the health and wellness professional’s services are making a positive impact on internal health, and Internal Age. The great thing about iHeart is that changes can be seen quite quickly with positive lifestyle choices. Allow your clients to see the real results of your services with iHeart Pro. More info at this link.
iHeart and iHeart Pro both use the same iHeart device, the difference is the application used with the iHeart hardware. The free iHeart Internal Age app is for consumer use, each iHeart app comes with the following:
- Five User Profiles
- Unlimited recordings
- An online dashboard for each profile created
iHeart Pro has been developed for health and wellness professionals, it is a paid app and includes the following:
- 500 User Profiles
- A detailed report after each recording sent to both the health and wellness professional and their client
- Online dashboard for all 500 User Profiles
Internal Age is the calculation of how stiff your aorta, the largest artery in your body, is, plus how your aortic stiffness compares to that of others at various ages in different populations. These calculations enable the iHeart system to determine how old you are inside.
Keep in mind that a single Internal Age recording is snapshot of your inner health. Use it as a starting point to measure the effectiveness of your training and lifestyle choices. Because immediate stressors that raise or lower your blood pressure raise and lower your Internal Age, you need to pay more attention to the longer-term trends you will see with the iHeart system. These trends, revealed on your personal iHeart website, track the sustainable effects your health-positive actions have on your Internal Age.
Aortic Stiffness results from age, inactivity, and less-healthy lifestyle choices. The longer these factors go on, the more evident the stiffening.
Aortic Stiffness, as measured by the iHeart System, serves as an indicator of just how much generalized stiffness you have inside and how that has aged you before your time.
Tracking your Aortic Stiffness gives you an objective metric to judge the effectiveness of your training and lifestyle choices. Lowering your Internal Age over time means that you are lessening your Aortic Stiffness and getting younger on the inside.
The iHeart System records your pulse waves and transmits them to the iHeart app. The iHeart app analyzes the data to calculate Aortic Pulse Wave Velocity (AoPWV). Your AoPWV shows how quickly the pulse wave, sent out by each heart beat, travels down your aorta to the bottom of your abdomen and back again. The stiffer the aorta, the faster the wave. Your calculated AoPWV is then compared to known values of different ages and populations to determine your Internal Age.
Read more about AoPWV on the Pulse Wave Velocity Wikipedia Page.
The iHeart system uses a calculation algorithm to determine Aortic Stiffness from Aortic Pulse Wave Velocity (AoPWV). This algorithm has been validated against the ‘gold standard’ of AoPWV and Aortic Stiffness testing. That standard measures AoPWV directly by timing the pulse wave as it moves past pressure sensors on a subject’s neck (carotid artery) and upper leg (femoral artery). Comparisons of data from the gold standard testing and from the algorithm confirmed the accuracy of the heart of the iHeart system.
Read more about the validation through the ‘gold standard’ of AoPWV measurement in the article, ‘Assessment of Arterial Distensibility by Automatic Pulse Wave Velocity Measurement’.

The iHeart System is NOT a medical device. It is to be used for personal health and wellness education only. It is not intended to be used for any medical diagnosis or management of any medical conditions. The iHeart system is to be used for personal health and wellness education along with regular visits to your Medical Doctor.
Your body is very dynamic, and you will see swings in Internal Age before and after exercise, before and after eating, while stressed, when you’re happy, and when you’re sad. These swings are normal. Blood pressure, heart rate, and other physiological parameters also change from moment to moment in a similar fashion.
Aortic Pulse Wave Velocity (AoPWV) scores can have a large range, the lower your AoPWV the younger your Internal Age. You can see ranges in the table below. The table below has been taken from an iHeart PRO report.
