We are looking for 13 to 17-year olds to interact with each other using a new phone app that we’re developing. Before the study, you will be asked to download our app. During the one-hour session, you will interact with other people live on your iPhone. We will ask you to share your thoughts in real-time as you explore different features. You will chat, watch a video, and solve problems together. A researcher will be on the line to guide you and ask you questions about your experiences. We're still building the app so we're going to use your thoughts and opinions to fine-tune it and improve it. We really value your feedback.
