What is iHeart®?The iHeart system is a health and wellness tool able to calculate Internal Age by measuring the stiffness of your aorta. Aortic stiffness is a proven metric for overall organ health and is capable of predicting risk of death from all causes. Scientific studies supporting this claim are available to read in the Science section of this FAQ. The iHeart system consists of:
- iHeart fingertip device
- iHeart Internal Age app
- Personal Online Dashboard providing recordings, calculations, and analyses of your Internal Age readings (stored on a secure server).
What is iHeart® Pro?iHeart Pro is a separate version of the iHeart app intended for use by health and wellness professionals, allowing them to demonstrate the immediately-measurable benefits of their services. Both versions of the app use the same fingertip device and a switch between iHeart Internal Age and iHeart Pro can easily be made at any time. iHeart Pro requires a low monthly subscription unlike the free iHeart Internal Age app. While the free app comes with five user profiles, iHeart Pro offers 1000. Unlike the free version, iHeart Pro emails reports after each test to both the wellness professional and the client for continued monitoring of progress, and access to the Personal Online Dashboard is available for all 1000 profiles.
How does the iHeart® fingertip device work?The iHeart device is a fingertip pulse reader that detects and records arterial pulsations in your finger. iHeart transmits these recordings to an app on your iOS/Android device and translates them into a pulse wave for display and analysis. After a 30-second you’ll be presented with an Internal Age. The iHeart device also measures real-time heart rate and blood oxygen saturation. Click on the highlighted links for a more detailed explanation of what these measurements mean.
What devices/operating systems is iHeart available for?iHeart is available for both iOS and Android (5.0+) phones and tablets. iHeart is NOT available for iPod’s or any personal computers/laptops.
How is the iHeart® device different from other fingertip pulse oximeters?Other pulse oximeters measure heart rate and blood oxygen saturation but their functionality usually stops there. iHeart does offer these measurements, but additionally is the only consumer-level product capable of measuring Aortic Pulse Wave Velocity and, subsequently, determining Internal Age.
Why is the iHeart® device so expensive?iHeart is an incredibly powerful tool and the first of its kind. The device has been tested extensively against the world’s gold-standard Aortic Pulse Wave Velocity testing system (the Sphygmocor system), which costs $25,000 and requires a trained professional to operate, and the results have been found to correlate with astounding accuracy. The free iHeart app also comes with 5 user profiles making it possible to manage the health of an entire household with just one device.
How does the iHeart® offer long term health benefits?The benefits of walking are well documented in medical research journals. Walking for just 30 minutes daily has been proven to 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. Why then, with such clear evidence, are physicians prescribing so much medication rather than leading crowds on early morning hikes? Physicians are primarily focused on the treatment of current ailments rather than the prevention of future ones. It is difficult for doctors to offer patients an overall assessment of health. iHeart measures aortic stiffness, a medically-accepted predictor of 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, and is known to predict risk of future heart disease and dementia in individuals as young as 30. Aortic stiffness is easily improved with exercise (including walking), a diet rich in omega-3 fatty acids, stress reduction, and multiple other factors. iHeart aims to guide people in making healthy lifestyle choices and to show objective results that lead individuals to feeling better and living longer.
Does the iHeart® system replace regular visits to the doctor?iHeart 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 and should not replace regular visits to your doctor.
Do iHeart® and iHeart® Pro use the same fingertip device?If you think you may have ordered the wrong version of iHeart, do not panic: you didn’t! iHeart and iHeart Pro use the same fingertip device and the differences are all in the which app you choose. This can be decided on/switched between easily and at any point.
How much does iHeart® Pro cost and how/when are the charges processed?iHeart Pro has a tiered pricing plan offering price breaks for longer subscription periods. They are as follows*: 1 month: $9.99 12 months: $100 When you download and open the iHeart Pro app you’ll be prompted to make your selection. There is no charge for iHeart Pro at point of sale. *all prices are in USD
How is iHeart® different from Nokia Body Cardio?The iHeart device measures Aortic Pulse Wave Velocity to determine Internal Age. Aortic Pulse Wave Velocity (AoPWV) is the gold standard of Aortic Stiffness measurement. Aortic Stiffness has been proven in a wealth of scientific literature to be a marker of risk of developing heart disease, dementia, and risk of death from all causes, but it’s reversible with positive lifestyle choices such as increased movement, improved diet, and lowered stress. The VitalSines team has validated iHeart against the gold standard measurement tool and iHeart correlates excellently with the gold standard results. We are currently working on a new validation study with the University of Illinois which will be published in six months. We will continue to do research to provide as much validation of the importance of AoPWV on a person’s internal health. The Nokia Body Cardio Scale* measures Pulse Wave Velocity (PWV) , which is not focused on the Aorta and is measured from the feet. This is not a very different method of measuring PWV and has not been validated against the gold standard. When a person is standing their blood pressure is increased which has an effect on PWV.
My Nokia Body Cardio won't measure PWV anymore, will this happen with iHeart®?Today Nokia announced that they will be pulling the Pulse Wave Velocity (PWV) measurement from their Body Cardio Scale. In the email sent to their customers they mentioned that there were potential regulatory issues with the PWV measurement. Pulse Wave Velocity is our specialty and we focus solely on this metric to help people get healthier. We have been selling iHeart for three years to people all over the globe. We are able to sell iHeart as a health and wellness educational device as it is non invasive and non diagnostic. We sell iHeart worldwide and have had no issues with any regulatory updates. Our team is dedicated to providing a robust tool that works well and provides valuable information. While we cannot comment on the reason Nokia pulled PWV from the Body Cardio, we can tell you that you do not need to worry about Aortic Pulse Wave Velocity being pulled from iHeart.
Is iHeart® FDA Approved?We are able to sell iHeart without FDA approval as a health and wellness educational tool. iHeart is non invasive and non diagnostic. iHeart does not replace visits to a doctor or provide medical information, it is to be used as a tool to track how your positive lifestyle choices are affecting your internal health, allowing you to make better choices and reach optimal health.
What is Internal Age™ and how is it calculated?Internal Age is calculated by comparing your Aortic Pulse Wave Velocity result to a graph of average healthy readings per age. Aortic Pulse Wave Velocity is a measure of aortic stiffness, a proven risk assessor for death from all causes and an indicator of overall organ health. iHeart tests will vary from minute-to-minute due to common fluctuations in blood pressure, so taking a daily baseline reading under the same conditions (i.e. after waking up and before having anything to eat/drink) is recommended to achieve consistent recordings. Internal Age is affected by exercise, stress, diet, etc., and over time this baseline reading will change in response to your lifestyle. By observing trends in your iHeart results you’ll develop a responsive understanding of your health.
How accurate is the iHeart® system?The iHeart system uses a calculation algorithm to determine aortic stiffness from Aortic Pulse Wave Velocity (AoPWV). This algorithm has been validated against the world’s ‘gold standard’ of AoPWV and aortic stiffness testing: the Sphygmocor system. The Sphygmocor system costs $25,000 and requires a trained professional to operate, including the placement of sensors on the neck (carotid artery) and upper leg (femoral artery). iHeart is the first consumer-level product of this kind. Results from the Sphygmocor system have been compared to those from iHeart and found to correlate with astounding accuracy as displayed in this graph. Graph: iHeart AoPWV vs. Sphygmocor AoPWV shows good correlation
What is a good Aortic Pulse Wave Velocity result?Aortic Pulse Wave Velocity (AoPWV) results are directly linked to your Internal Age reading so, simply put, the lower your Aortic Pulse Wave Velocity (AoPWV) score, the better your health. A younger Internal Age reading than your actual age can be considered good! The table below has been taken from an iHeart Pro report to better explain how AoPWV values correlate with Internal Age scores.
Why should I care about aortic stiffness?Aortic stiffness is a proven risk assessor for death from all causes and is an indicator of overall organ health. Stiffening of the aorta occurs with age, and in response to inactivity and other less-healthy lifestyle choices. By measuring Aortic Pulse Wave Velocity and monitoring your own aortic stiffness with iHeart, a level of mindfulness is applied to your own overall health that can positively affect your lifespan.

Does it matter which finger/hand I use in the iHeart® device?We recommend that you use your index or middle finger. This can be on either hand. Cold hands or poor circulation may affect your reading but this can usually be overcome by rubbing them together and clenching/releasing your fist a few times to stimulate blood flow.
How can I get the most out of my iHeart® device?There are a few things to keep in mind when taking an iHeart reading to maximize results and your understanding of them:
- Rest for 2 minutes before testing.
- Rest your arm on a flat surface such as a table or your leg throughout the test.
- Take a reading at the start of each day to establish a Baseline. This is the number that you want to see change over time as it is reflective of your overall health.
- Non-baseline tests taken throughout the day will vary due to common fluctuations in blood pressure. By observing trends in your iHeart results you’ll develop a responsive understanding of your internal health. Readings are affected by exercise, stress, and other factors, and tests taken throughout the day can be useful for recognizing short term effects of stress and other lifestyle choices.
How can I positively affect my iHeart® Internal Age recordings?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
What will negatively affect my iHeart® recordings?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
What does the red dot on my iHeart® results mean?The red dot on the pulse shape at the top left of your iHeart results screen signifies the beginning of the Aortic Reflected Wave. Please refer to our blog post, ‘Aortic Pulse Wave Velocity (AoPWV) vs. Pulse Wave Velocity (PWV)’ for a more in-depth look at the Aortic Reflected Wave.
Why isn't my iHeart® device connecting to my phone/tablet?
The iHeart device connects to your phone/tablet via Bluetooth. Please make sure that bluetooth is enabled on your phone/tablet before beginning an iHeart recording. The phone/tablet and fingertip device should pair automatically the first time you use iHeart. If this does not seem to be the case, click on the gear icon at the bottom right of the app home screen, press ‘Install New Device’, and turn on the iHeart (white button). Depending on the model of your phone/tablet you may receive a notification that the device has been connected. Do not panic if you did not receive such a notification: they should still have paired.
This will pair the devices indefinitely. You do not need to pair your devices through your phone’s own bluetooth settings. If you continue to experience difficulty please contact email@example.com.
How do I turn on the iHeart® device?
Press the black button on your iHeart device to turn it on. iHeart will turn itself off after 10 seconds of inactivity to preserve battery life.
The iHeart® device takes two AAA batteries. Unfortunately we do not ship with batteries as it makes shipping times much slower and also reduces certain countries where we can ship.
Why can't I log in to my Personal Online Dashboard?
In order to log in to your Personal Online Dashboard your iHeart device must be registered (see next question). If your device is registered, an email will be sent to the email address you entered containing instructions for logging into your Personal Online Dashboard.
How do I register my iHeart® device?
When you open the iHeart Internal Age or iHeart Pro app for the first time you’ll be prompted to register your device. If at any point you need to alter your registration information you can click on the gear icon at the bottom right of the app home screen and then press ‘Register’. From here you can create a new account or log in to an existing account.
Why is the iHeart® oximeter display upside down?
To flip the display on the fingertip device simply press the black power button once.
Why are iHeart® Pro reports not being sent after testing?
For reports to be sent to you and your client’s emails, your phone/tablet needs to be connected to wifi in order to synchronize data with the iHeart cloud. On the settings screen of the app, make sure that wifi is enabled and allow the app time to synchronize. When this is complete, reports will be sent to the registered email address AND the email address on the testers profile.
If for any reason this is not working correctly, please try quitting and app (double-tap the home button of your phone/tablet and swipe the iHeart Pro app off the screen) and re-open it. The app will begin the synchronizing process, pushing data to the server and sending out any unsent reports. You will notice the words ‘Synchronizing’ with a percentage in the top right corner of the screen.
Why does my Internal Age vary so much sometimes?
Your body is very dynamic and you will see variations in Internal Age in response to exercise, eating, stress, and myriad other factors. These variations are normal. Blood pressure, heart rate, and other physiological parameters change from moment to moment in a similar fashion and affect your Internal Age readings. Refer to ‘How can I get the most out of my iHeart device?’ in the Testing section of this FAQ for a better understanding of how these variations can be interpreted positively.
Why won't my iHeart® pair with my Android phone?
The Android platform has determined that a bluetooth signal is capable of revealing a user’s location. Therefore, when your iHeart app opens and it prompts you to confirm or deny access to your phone’s GPS settings, it’s important to allow this permission.
For ease of use, iHeart scans for a bluetooth connection automatically and pairing cannot be manually set up in your phone’s bluetooth settings (all pairing is done inside the iHeart app). It is because of this automatic scanning that this is a requirement; other bluetooth devices receive this permission when you manually pair them with your phone.
