DESCRIPTION E4 realtime is a research application that allows you to visualize live physiological signal data from the Empatica E4 wristband. E4 realtime stores streamed data and automatically backs up data to your Empatica Connect account after the streaming session is completed. In order to use this app, you need a compatible Empatica E4 wristband research device. The E4 realtime app does not work with the Embrace watch.
