I have not been able to connect EVOLV to the Omron app. There is always an error message. Omron support does not respond. I cannot give any information about Samsung Health.

The Omron app must be downloaded and used for control. However, the data can be automatically stored in Samsung Health. It is possible to link the Omron App with S Health.

The device is not compatible with Samsung Health, you need to download the app OMRON connect.
