Define Product Metrics
Design a metrics framework that measures both engagement and business outcomes for a mobile fitness app.
The scenario
Use the scenario to understand the project context and what you’ll be working on.
You're the product manager for a mobile fitness app that offers workout plans and tracking. The app has 250,000 monthly active users but struggles with long-term retention. The executive team has asked you to define the most important metrics to track and explain how they relate to user success and business outcomes.
Here are the key statistics:
- User funnel showing drop-offs at key points (sign-up, first workout, subscription conversion)
- Retention curve showing a significant drop after 30 days
- Revenue breakdown by subscription type and in-app purchases
- User survey highlights about motivation and usage patterns
- Current dashboard screenshots show vanity metrics that don't drive decisions
