Intelligent sportswear with an integrated real-time stress ECG system

HeartBit is the world’s first device capable of stress ECG monitoring that is available in a comfortable, wearable format that fits into our training top made of high-quality moisture-control fabrics.

Listen to your heart!

HeartBit is a compact measurement device capable of recording and assessing a real-time medical-grade ECG that allows timely detection of arrhythmia, atrial fibrillation and potential anomalies.

Personalized training program based on your cardiac status

Comparing the warmup ECG's with the previous session's recovery phase, HeartBit can provide status warnings and recommend a personalized training plan tailored to the desired goal.

Reach your goal and stay with us on the safe side!



Custom developed algorithm detects, analyses and reacts to irregular heart beats during sports activities


Continuous, real time recording and assessment of ECG data


Tailored training plans according to your cardiac status and desired goals


A combined hardware and software solution that filters all disturbing background noise, to provide the clearest possible signal for the algorithm


HeartBit takes measurements at a frequency of 2,000 Hz per electrode, which means 10,000 data points per second in total. Competing devices measure one or two data points per second. HeartBit contains a risk-analysis algorithm, which is capable of diagnosing the symptoms of sudden cardiac arrest, stroke and ischemia, and provides immediate warning to the wearer during exercise. The combined hardware and software solution permits the separation of disturbing noises and valuable inputs from the heart, the muscles and the outside environment – providing the clearest possible signal for the algorithm.

Development Team

The development team consists of 5 PhD members who complement each other in mechanical engineering, information technology and health sciences. The inventor and lead developer of the devices is Professor Dr. György Kozmann, who has over 50 years of international scientific research experience in physics, biology and information technology. Our team is a strong, agile, and disciplined development organization with experience in Body Surface Mapping, physiological sensors, communications technology, and mobile applications.

Executive Management

The management team consists of experienced entrepreneurs, who already have a positive track record of developing healthcare devices such as the WiWe or the iKnife. György Kozmann, is the CEO and former managing director of Neato Digital Ltd., a wearable sensor technology firm. Gábor Szabó is the Head of Business Development with an extensive experience in medical technology. Susan Forrester, a Fellow of the Australian Institute of Company Directors, is a board member and an early investor, so as Gábor Vilhelm, founder of Considero Investments and Ákos Tallós, the CEO of MediMass in Hungary, both of whom have an advisory role in the company.

Official IBM Business Partner

HeartBit for Smartphones

For the best user experience, download the HeartBit mobile application in the AppStore or in GooglePlay. Beside history reports of your workout, you will also benefit from the Quick Run or Personal Trainer function, the latter helps you reach your desired goal under supervision. Within the application you will also have the chance to build your social network, compete with your friends and achieve new rewards; from a clinical point of view, you can also send your cardiac report to the doctor within one click.


Recovery is an important metric! It’s shown in many studies that if the heart rate recovery is slow, that suggests the heart condition is not ideal and you need better conditioning.
