We help researchers and companies to collects and analyzes data from mobile apps - GDPR compliant & transparent. This includes: - Which ads do participants see in everyday life in social media apps? - What does the buying journey look like on shopping apps (e.g., seen products, purchase price)? - Which apps do participants in general spent their time in? - How do participants move in the real world (location data such as GPS-data and mobile network)? - Smart questions (i.e. user played Candy Crush for 30 minutes - a pop-up appears “How do you feel?”) The technology is built upon the Menthal project, a unique scientific study of the behavior of more than 700.000 smartphone users that has been running since 2014 at the University of Bonn. legal notice: https://murmuras.com/legal-notice/
