Engagement - the holy grail of health apps

Downloading health apps isn’t enough to drive impact. Users need to see a benefit, be engaged and stay interested enough to actually use them.  Easier said than done; most apps and especially health apps struggle to achieve user engagement and retention.

Retention of juli users after 30 days. (Industry average: 3.7%)

Engagement: More than half of the active juli users use the app at least twice per week.
