High CAC, Low Week-One Retention
FitTrack had achieved strong product-market fit with a workout tracking app praised in fitness communities — but growth had plateaued. User acquisition cost climbed 40% over six months while day-7 retention sat at a disappointing 22%. Feature-focused ad creative failed to differentiate FitTrack from dozens of competing fitness apps. The growth team needed a campaign that would lower CAC, improve onboarding completion, and build a visual language scalable across Meta, Google, TikTok, and influencer partnerships.
