The E4 and Embrace serve two different purposes and are designed for two different types of users.
Embrace is optimized to detect unusual movement patterns and changes in physiological signals that could be associated with convulsive seizure. It’s companion app, Alert App, notifies caregivers when Embrace has detected a possible tonic-clonic seizure.
The E4, on the other hand, is designed specifically for researchers looking to gather physiological signals in real-time and perform after-the-fact analysis. We don’t recommend it for consumers as the data is not summarized, and requires experience in data analysis to understand. For larger studies, the Embrace can also be used as a research tool, but would require a subscription for raw data exportation, while the E4 does not require a prescription.
Use
In addition to monitoring and alerting for possible tonic-clonic seizures, Embrace can also track rest and physical activity.
The portability of the E4 wristband allows researchers to either record physiological signals in at-home settings or in the lab. After recording, they can easily access the data for more in-depth analysis. With our developer tools, they can even build their own app using real-time E4 data.

The apps associated with each device are different. E4 software does not work with Embrace and vice versa.
