Dark patterns are user interface elements that can influence a person’s behavior against their intentions or best interests. Prior work identified these patterns in websites and mobile apps, but little is known about how the design of platforms might impact dark pattern manifestations and related human vulnerabilities. In this paper, we conduct a comparative study of mobile application, mobile browser, and web browser versions of 105 popular services to investigate variations in dark patterns across modalities. We perform manual tests, identify dark patterns in each service, and examine how they persist or differ by modality. Our findings show that while services can employ some dark patterns equally across modalities, many dark patterns vary between platforms, and that these differences saddle people with inconsistent experiences of autonomy, privacy, and control. We conclude by discussing broader implications for policymakers and practitioners, and provide suggestions for furthering dark patterns research.

A Comparative Study of Dark Patterns Across Web and Mobile Modalities
This paper investigates variations in dark patterns across different platforms (mobile app, mobile browser, web browser) for 105 popular services. Findings show that while some dark patterns are consistent across modalities, many differ, leading to inconsistent user experiences regarding autonomy, privacy, and control. The research concludes with implications for policymakers and practitioners, and suggestions for future dark patterns research.
