mySASY training is an application that allows you to easily and very accurately evaluate the activity of the basic system in the human body = the Autonomic Nervous System (ANS) using a mobile phone and an HRV monitor. The autonomic nervous system controls the most important processes and the condition of the human body. Thanks to this measurement it is possible to monitor the long-term and current reactions of the organism to the selected training processes/regime and significantly increase the efficiency of the training.

The mySASY mobile application is used for measurement/monitoring and is intended for all mySASY users with an individual account and active program FREE, BASIC +, SPORT or SPORT +. The analysis results are displayed on Dashboard or by selecting History. At any time, you can log in to your account directly at https://client.mysasy.com/en, from any Internet browser and from any device (mobile phone, tablet, PC).

HRV monitor is required for measurement with mySASY. We offer our HRV monitor at https://eshop.mysasy.com/accessories?utm_source=ios. But if you already have an HRV monitor you can use your own. For monitoring with mySASY system, the device has to meet the following technical requirements:
• It must be connectable via Bluetooth (BLE).
• It must be able to measure the RR interval (pulse) accurate to one-thousandth of a second (0,001). .
(Even though monitors from other manufacturers meet these parameters, mySASY a.s. is not able to guarantee the measurement accuracy of all third-party devices.)

Controlling the application should be as intuitive as possible. In case of any problems or questions, please contact: support@mysasy.com
