Prioritisation / North-Star Metrics

Exclusion

  1. Revenue & Monetisation

Reason: 

  1. User Trust and Privacy: Health-related data is extremely sensitive, and users need to trust that their data is being handled responsibly. Aggressive monetization strategies could lead to privacy concerns and erode user trust.

  1. User Experience and Value: The primary goal of a health app should be to provide value to the user by helping them manage their health effectively. Prioritising revenue can lead to decisions that degrade the user experience, such as intrusive ads or paywalls for essential features.

By prioritising user engagement, retention, and trust, Apple can ensure the long-term success of the Health app and its broader health initiatives, creating a more sustainable and ethical path to revenue.
