It's up to you. We recommend measuring every other day. But the most important thing is to keep the morning measurement, right after waking up.

It does not interfere. The data we have about users is not shared with anyone and is carefully secured. Additionally, in the app, we offer the option to completely delete an account along with all user data (paired activities, measurements, personal and health information).

Thanks to the most accurate measurement of HRV by spectral analysis, we are able to capture the activity of both the regenerative and stress branches of the CNS (central nervous system). Their activity shows how stressed you are and how much regeneration you have.

If you have a smartwatch like Apple Watch, Samsung Watch, etc., and are considering using an Elonga sensor, check out elonga.com/smartwatch, where we cover the topic in detail.The primary difference is that each service specializes in something completely different and they complement each other perfectly. Elonga focuses on measuring your total body health in 3 minutes in the morning - bringing you unique objective data on stress levels, recovery, readiness and functional age. In contrast, the smartwatch is used to measure activity throughout the day - showing you how many steps you've walked, calories burned, etc.‍Elonga then synchronises the measured data into a movement plan, through which it provides you with recommendations for the most appropriate activities for each day.
