Empatica Care Lab vs CARWatchApp

The Care Lab App is part of Empatica’s research ecosystem for academic and institutional research and longitudinal studies. The app uploads data collected from the EmbracePlus wearable to the Cloud, so it can be accessed by researchers. Key features include: Live status check of the system Continuous, automated EmbracePlus data streaming Wearing time indicator to safeguard adherence Smart troubleshooting and notifications Easy onboarding for EmbracePlus Secure, de-identified login credentials The Care Lab App is intended for research use only and should not be used as part of diagnostic or clinical procedures.  Care Lab is not intended for medical or diagnostic purposes. Always seek the doctor’s advice if you feel unwell.  Care Lab should never be used to make medical or diagnostics decisions.

CARWatch is an open-source research application designed to support accurate and standardized saliva sampling in psychoneuroendocrinological studies. The app enables objective recording of sampling times using barcode scans and automated reminders, reducing reliance on self-reports and improving data validity. Originally developed for assessing the cortisol awakening response (CAR), CARWatch has evolved into a flexible framework supporting a wide range of saliva sampling protocols, including full diurnal cortisol profiling. Researchers can configure study parameters via a companion web interface and distribute QR codes to participants for seamless setup. The app then guides participants through the sampling process, records timestamps, and logs all interactions for later analysis. This app is a research-enablement tool and is not itself the sponsor, operator, or investigator of any specific study. It is used by external research teams and institutions to support the collection of CAR study data. Key features include: - Barcode-based logging of saliva samples for objective timestamping - Flexible alarm scheduling (relative to awakening or fixed clock times) - Support for multi-day and multi-sample study designs - Daily overview of completed, pending, and missed samples - Retrospective logging of missed samples - QR code–based study configuration - Built-in tutorial for participant guidance - Privacy-preserving design with no backend data storage CARWatch is intended for use in scientific studies and is not a medical device. It does not provide medical advice or diagnostics.
