This project aimed to motivate people to apply sunscreen daily through a website that provided reminders and information. The website targeted Stanford undergraduates aged 18-22 who surf the internet regularly. While half of participants applied sunscreen at least 5 out of 7 days and most said they would continue, the effectiveness depended on users' browsing habits. For best results, the reminder should be visible on the desktop or as a top site thumbnail rather than only on the home page.
