The participation is voluntary and there is no monetary reward for your participation. We hope, however, that you will find the application useful as it will provide you with your personal activity map. You will be able to identify the connectivity quality of the last known 3G/4G connection, the last applications generating traffic in upload and download, your total travelled distance since the last upload to our servers, as well as the date of the last upload session. This visualisation might give you a new perspective on your mobile phone usage. Finally, any results coming from this project might result in a scientific publication. We will be happy to share an electronic version (via our website) whenever the copyright laws permit us to do that.
