This is not the official Google App Store, it has been developed to to test some user interface concepts that we have developed.We invite you to participate in our research project.If the research is succesfull then an app store search utility will be published with our improved user interface.The goal is to install 5 apps from the designated categories.Installation will be simulated and will not really modify your device. In the beginning there will be a small voluntary survey which can be filled in. We ask that you take the time to fill it in completely.After you have selected 5 apps, 1 final question will be asked. When you fill in the last question, click on the 'End' button to submit the research data to our servers.Thank you very much for your participation!
