A few years ago, a popular fitness app, let’s call it “FitPulse,” noticed a worrying trend. User engagement, the lifeblood of their business, was dipping. The team huddled together, looked at their dashboards, and saw the drop coincided with the summer months. The conclusion seemed obvious: people were on vacation, enjoying the outdoors, and spending less time on their phones. They decided to ride it out and plan a big re-engagement campaign for the fall. But the numbers kept getting worse. What they missed was buried in their app store reviews and support emails.
