Frequently Asked Questions

How often should I measure?

It's up to you. We recommend measuring every other day. The key is to always measure in the morning, right after waking up.

Does the app compromise user privacy?

No. We never share your data with anyone, and it's securely stored. You can also delete your account and all associated data at any time.

What exactly do stress and recovery values mean?

Using the most accurate HRV method - spectral analysis - we measure the activity of both the stress and recovery branches of your autonomic nervous system. This shows how stressed you are and how well you're recovering.

How is Elonga different from smartwatches (Apple Watch, Samsung, etc.)?

Using a smartwatch like Apple Watch or Samsung Galaxy Watch? Learn more at elonga.com/smartwatch where we cover the subject 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.
