Bluetooth Oximeter Sensor for Android and iPhone StressLocator Application

NEW - compatible with project HRV Mind Machine


The instrument measures the oxygen saturation SPO2, pulse rate, and pulse intensity PR these physiological signals for the person being monitored, including oxygen volume wave and transmits to the smartphone or tablet with Android.

Heart variability allows you to monitor your health status and evaluate your sleep quality in the long run.

About The Android Application StressLocator

The StressLocator, which has been developed for almost one year, consists of three main parts: a sensor, which measures pulse waves, client application for Android, and server application. These three components allow you to measure mental and physical stress and quickly estimate your current condition. Measurement can be done anywhere where you have your mobile phone with an installed client application. The sensor ensures precise measurement and comfort. The results can be used to plan your activities and thus utilize your potential.

The application with its results is based on a wide range of graphs, which precisely calculate your condition. The weakest point is the sensor with which you measure. We strongly recommend purchasing our blue-tooth oximeter sensor. Interpretation of data is based on deep research, study, and analysis of known work in this field.

Apart from that, the application offers breathing exercises allowing you to quickly improve and train your concentration or relaxation and new exercise allowing you to try a classical meditation.

The iPhone Application is slightly different and doesn't contain all the functions, for example Save Astronauts game and Meditation exercise.
