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. If you want to know more, please contact Empatica at email@example.com or check our website www.empatica.com/research/e4/.
The E4 realtime app allows you to visualize the following physiological parameters from the E4's onboard sensors:
• Blood-volume Pulse (BVP) waveform and current heat-rate
• Electrodermal Activity (EDA) waveform and current skin conductance level
• Accelerometer state
• Peripheral temperature
At Empatica, we deeply care about the experience of our researchers.
In this version we introduced Landscape orientation to improve the visualization when mirroring on a TV screen or a monitor.
• Better on-wrist detection logic showing on-wrist status also in main screen
• Heart rate value is dimmed if the device is not on wrist
• Tiny layout enhancements for iPhone X and for small factor devices like iPhone 4S, iPhone 5 and iPod Touch
Version 2.0.0 - 2.0.5

Helpful app; don't mind those one-star reviews
So the app is great. Intuitive UI, super easy sync with the E4, and having a battery indicator is helpful. Nicely done.
If I were the picky type I'd mention that the UI sometimes freaks out when you transition from streaming to the dashboard in vertical orientation. Everything stretches. It's minor and easily fixed (just turn the phone).
Oh, and I'm pretty certain all the one-star reviews are from people with Embrace devices trying to log in with those credentials. This app requires an E4 device and will not work with an Embrace. Different accounts. That said, it would be lovely if Embrace worked with this app.
Hi, thanks for your feedback. We’ve released a new version 2.0.2 of E4 realtime and we invite you to update. It includes many fixes and improvements, and we hope you’ll like it. Email us at firstname.lastname@example.org if you have questions.
