Comoray has developed a technology that helps people to read, monitor & track personal health data themselves; non- invasively and cost effectively. The technology comes as a single algorithmic core that can be fully integrated and optimized on a hardware platform, but also be a plug-in unit or even a cloud service. It can be used for a large variety of wearable and wireless applications without accessories.  The technology is, for the time being, capable of extracting heart rate, respiration rate, blood pressure, saturated oxygen and acidity by batches or streams of photoplethysmography (PPG) signal samplings. The accuracy of the obtained measurements is usually at least 95% of alternative measurements on freely available medically-approved of-the-shelf devices.
