We are seeking study participants for an academic research project at LMU

About this research study

The study aims to improve the participants' stress awareness and evaluate the effectiveness of various recommendations against stress. Study participants collect their heart rate data using a Fitbit tracker/smartwatch or a Google Wear OS smartwatch. The data is synchronized via an Android app and then processed and displayed in a web app. Participants are encouraged to record their daily activities and feelings regularly to provide more accurate computation models.

We expect participants in this study to benefit from increased stress awareness and recommendations against stress.
