HEar Studie app for iPhone and iPad

We are researchers from the Karlsruhe Institute of Technology. This app will be used for collecting data to study the relationship between headphone usage, personality and few health metrics. We ask the user to answer some survey questions on general demographics, headphones usage and personality. Finally, we request the users to share their audio exposure metrics and few other health variables like HRV, blood pressure and exercise times. This data is collected completely anonymous. All the measures have been taken to store it securely and will be used only for research.
