• High drop-off rate during initial onboarding flow • Poor activity conversion, to food and symptom tracking • Low free-to-paid conversion rate (2.1%) • Needed to balance demonstrating immediate value with long-term engagement (as the real value comes with long term use of the app)
šŸš€ Objectives
• Redesign onboarding to improve completion rate and initial engagement • Optimize user flows based on actual usage patterns • Increase subscription conversion rates • Improve overall retention metrics for paying customers

Example Usability Insights & Implementations

Onboarding and Tutorial Optimization

  • Issue: Initial tutorial overwhelmed users with too many features at once
  • Solution: Implemented progressive onboarding focused on immediate value (food tracking) before revealing advanced features
  • Result: Increased onboarding completion rate from 64% to 89%, with 72% of users logging first meal within 24 hours

Food Logging Workflow Redesign

  • Issue: Session recordings revealed users frequently needed to log multiple food items but were forced into symptom tracking after each entry
  • Solution: Implemented bottom sheet modal allowing batch food logging before symptom entry
  • Result: 43% increase in average food items logged per session and 28% reduction in abandoned logging sessions
