      App for Mobile: HR, Stress/Fatigue level/Cardio Vascular screening

      Why Atrial Fibrillation matter for you? Why accuracy matter?

      According to WHO, more than 10 000 000 people die every year due to cardiovascular diseases. What is even more shocking, 80% of these deaths could have been prevented. We live in a busy world, and it’s often hard to convince yourself to visit a hospital without actual need. Our goal is to provide people with an easy-to-use tool for medical-grade accuracy heart monitoring, which can be performed anywhere.
      Low accuracy HRV in wearables is happened now (according to publications, which you can check here, here, here and here):
      Our systematic review revealed that wearable devices, especially those using PPG, may provide a promising alternative solution for measuring HRV. However, it is evident that more robust studies in non-stationary conditions are needed with appropriate methodology in terms of a number of subjects involved, acquisition and analysis techniques implied, before being able to recommend any of the commercially available devices. Therefore, so far wearable devices can only be used as a surrogate for HRV at resting or mild exercise conditions, as their accuracy fades out with increasing exercise load.

      About HeartIn

      Founded in 2014 in Miami, Florida, HeartIn Inc. is constantly driving innovations forward, aiming to accelerate the development of telemedicine and remote cardiology in particular. After more than 9 years since the initiation of the idea, dozens of various prototypes and continuous development, HeartIn is ready to present its product – the future of remote cardiac assessment, which is available already today.

      Our History

      Illustration

      2014. The story begins…

      HeartIn starts developing its first product, a portable 12 lead ECG. After the number of clinical trials, the device is validated and the sales process begins.
      Despite the high accuracy and relative simplicity, the product was not a perfect fit for end-consumers. Attaching electrodes to the body takes just a few minutes, but it still requires certain attention and right placement.
      We aimed to develop a convenient solution, which can be used by everyone, from child to senior, but it appeared to be too complicated.
      Giving up is too easy. We moved further…

      2015. New Vision.

      The next idea was to build a bracelet-like ECG monitor, different from all fitness trackers ever existed. Unlike others, HeartIn focused
      You may still find a lot of similar solutions on the market. Most of them are cheap, convenient and easy-to-use, however, they do not fulfill the main requirement — constant heart monitoring.
      With such a product you can only perform an interval monitoring, at the point of time you think it is necessary, which, unfortunately, does not guarantee you are healthy. Furthermore, the data sample collected during such monitoring is relatively small and it can be taken only during a resting state, thus, the measurements may not fully describe the real situation.
      We did not want to focus on “almost” good solution, and this is why our journey continued…

      Convenient monitoring everytime and everywhere

      All the magic is hidden beneath. HeartIn Fit smart garment is equipped with two built-in textile nanoelectrodes, placed at the inner part of the t-shirt at the chest level. These electrodes, as well as the t-shirt itself, are made of soft hypoallergic fabric, which does not cause irritations and is comfortable to wear all day long. Also, you do not have to attach stickers, plug in cables or shave your chest — just wear the t-shirt and start the monitoring process. When you finish the monitoring, don’t be afraid of putting HeartIn Fit into the washing machine: it is a durable t-shirt that survives more than 300 washes!

      Frequently Asked Questions

      • Is this something that I can wear all day and is it worth taking readings from both walking as well as sitting around?

        Yes, you can definitely wear it all day! It will provide valuable information both during workouts and during recovery as well. The app will interpret the results for you and will display them in an easy to understand format.

      • How different is your ECG compared to bigger brands like MOOV HR ECG?

        MOOV HR ECG is “ECG grade” blood perfusion sensor, which indirectly measures heart rate. 3rd party publications say that indirect heart rate monitoring could be 70% correct. Heartln is ECG/EKG measuring device. ECG/EKG method is 99.9% correct in measuring the heart rate. MOOV HR ECG can measure the TRIMP only but Heartln measures heart rate variability (the source to calculate the time you can work effectively, the time points to have a rest and restart your activity, level of psychological stress), and can detect different kinds of heart rhythm irregularities and alarm about dangers in real time.

      • How to choose the size of a t-shirt?

        After you press the “BUY NOW” button and we receive your payment, you will get a form with questions to choose the size as precise as possible. HeartIn is not just a regular t-shirt, that is why it requires a certain attention to size choice. But don’t worry, this is a fast procedure and we are always keen to help you with this.

      • How frequent do you foresee the mobile app be updated to incorporate further details or smooth out any bugs?

        Applications are self-learning and are updated as new data becomes available or when errors are detected.

      • Are you planning to implement integration with Google Fit and Apple HealthKit in future?

        The Healthkit integration for HeartIn is completed. Google fit is in progress.

      • How tight does the shirt need to be to get a good reading?

        The most critical part of the body that needs to be in constant contact with the reading devices of HeartIn is the bicep area where the device clips on. That area is definitely designed to fit snuggly to help make sure there is contact. Secondarily, the chest and upper back should be as a close a fit as possible.

      • How sweat/water resistant is the ECG device?

        It could be used in all circumstances except pool and open water.

      • What is the difference between the 1 lead and 12 lead ECG - how much more information are you going to get?

        The difference between the 1 lead ECG and 12 lead ECG won’t have a dramatic impact on what information you can glean about your athletic performance itself since 1 lead is sufficient for a lot of the analytics we planning to provide. What 12 lead does bring to the table is a much more in-depth overall ECG signal which doctors and cardiologists may be willing to look at to glean insights given its similar accuracy to the devices they are used to working. As such, the 12 lead ECG offering is really designed for people who want that extra layer of accuracy across the board and who may want to share HeartIn data with their doctor.

      • I'm worried that the shirt will not be tight enough around my bicep to measure the ECG signal.

        Tightness around the biceps does not affect the measurements because it is not the place of electrodes.

      • Can I leave my phone in the locker while I do my workouts?

        The data is analyzed remotely (to maximize the quality of analysis), and because of that, the use in this version is possible only if you have a phone in the range of the device.
