Executive Summary

This research from Varun Grover at the Sam M. Walton College of Business, University of
Arkansas (Department of Information Systems), together with academic collaborators,
examines how sharing user data on mobile platforms influences third-party app (TPA)
performance. Using the rollout of Apple’s HealthKit as a natural experiment, the study
analyzes how data-sharing participation shapes app innovation, competitive dynamics, and
ultimately, user demand.

The research highlights a fundamental strategic tension. Shared data may broaden an app’s
strategic reach by enabling diversification into adjacent markets—a pathway that tends to
improve performance. At the same time, access to a common data pool makes it easier for
rival apps to create similar features, reducing differentiation within the focal market and
intensifying competition. The findings suggest that while data sharing can fuel innovation
and growth, it may also erode competitive distinctiveness and weaken performance if rivals
diversify more aggressively or imitate key features.

For leaders navigating digital ecosystems where openness is increasingly expected, the
research underscores the importance of managing both the upside and downside of data-
sharing initiatives.

Action Items for Industry

  • Protect differentiation when participating in data-sharing initiatives: Use
    proprietary analytics, design capabilities, or intellectual property strategies to
    maintain uniqueness even when data pools overlap.
  • Leverage data sharing to explore adjacent markets: Treat shared data as an
    engine for responsible expansion into complementary offerings that broaden user
    value and demand.
  • Monitor rival responses to your openness decisions: Recognize that your
    participation may accelerate competitors’ diversification or imitation, affecting your
    market position.
  • Balance openness with internal governance: Establish guidelines that encourage
    innovation without undermining the competitive identity of your app or platform.
  • Evaluate platform policies with long-term ecosystem health in mind: Data-
    sharing structures should align incentives for innovation while limiting excessive
    feature convergence.

Quote from the Researcher

“In mobile ecosystems, data sharing is a double-edged sword: it helps apps grow into new
markets even as it makes them easier to copy in their own.”
