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 sales@empatica.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 ## Key features - Live physiological signal visualization - Blood-volume Pulse (BVP) waveform - Electrodermal Activity (EDA) waveform - Accelerometer data - Peripheral temperature data - Automatic data backup ## Recent user reviews (10 of 14) All indexed reviews: https://appshunter.io/ios/app/empatica-e4-realtime/id702791633/reviews.md ### 1/5 — Can’t login *2022-07-13* Setup an account online which requires my credit card, address, birthday, lots of info they don’t need. Still can’t login to the app with the account. ### 5/5 — Great research app *2019-05-06* Allows us to monitor the quality of the incoming data in real time and adjust the E4 if needed. This has been fantastic for our physiological research. ### 1/5 — Log in issues *2018-09-24* The app will not let me log in. ### 1/5 — How to log into the app? *2018-07-20* How to log into the app? ### 1/5 — USELESS APP *2017-03-29* USELESS APP!!!! Pls don't waste your time and effort on this. **Developer response:** Hi, sorry to hear about your experience. 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 support@empatica.com if you have questions. ### 5/5 — Helpful app; don't mind those one-star reviews *2017-01-25* 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. **Developer response:** 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 support@empatica.com if you have questions. ### 1/5 — So smart yet so dumb *2017-01-13* If zero stars was an option, I would be there. Like others,I wasted half an hour trying to login. I've reset the account password, created new accounts, tried multiple times. Zero, zilch,nada. This worthless app won't let me login. **Developer response:** Hi, sorry to hear about your experience. 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 support@empatica.com if you have questions. ### 1/5 — Useless *2016-12-22* Can't login... and why are there three apps. Why can't we have all the information in one place. Myfitbit tells me everything I need to know.... my son's watch should too. **Developer response:** Hi, sorry to hear about your experience.

At all *2016-12-14* I also could not log in, and I'm sure I used the correct username and password ### 1/5 — Cannot log in *2016-12-12* Useless app, like others cannot log in. ## Frequently asked questions about Empatica E4 realtime ### What is Empatica E4 realtime used for?
