Context and Challenges
The BodyFast: Intermittent Fasting app operates in a highly competitive Health & Fitness segment, estimated at around $16.2 billion in 2024. Intermittent fasting apps account for roughly 8–10% of this market, creating intense competition for user attention. The main user acquisition channel was Facebook Ads, where traditional promotion methods (static banners, neutral visuals) had not achieved sufficient user engagement or retention.
At the start of the project (Q2 2024), the Facebook Ads performance for iOS showed concerning metrics: average CTR was only 0.8–1.0%, D7 retention hovered around ~17%, and the cost per install (CPI) was about $2.5–$3.0. Although these figures were acceptable, they were far from optimal for pushing the app into the category's leadership ranks. The challenge was not only to increase Facebook Ads performance but also to reduce dependency on paid traffic, strengthen chart rankings, and drive organic growth.
Key Challenges and Metrics
- Increase CTR and Reduce CPI:
Improve ad appeal to generate more relevant installs for the same budget. - Enhance Retention (D7, D30) and Boost LTV:
Deepen user engagement so that users don’t just install the app, but continue to actively use it. - Improve Chart Rankings and Increase Organic Share:
Achieve a “snowball effect” of organic traffic, reducing reliance on paid promotion.
For clarity, here’s a comparative table of the key performance indicators before and after the UGC implementation:
Creatives Inspired by Real Experiences
Before analyzing the results, let’s look at the UGC creatives that delivered these improvements. Over the first 4–6 weeks, we tested various formats, monitored reactions, and optimized targeting. The most effective creatives reflected real user and expert experiences:
A real person shows their progress, daily routine, and how the app fits naturally into their life. This creates a “follow-the-leader” effect and builds emotional connection.
Authority of a professional athlete builds trust and credibility, especially when speaking about discipline and results-driven approaches to health and fitness.
An authentic testimonial from a successful long-term user demonstrates the app's effectiveness and accessibility, inspiring trust and showcasing sustainable health benefits.
Assessment-driven approach that combines a relatable goal with an easy first step, encouraging immediate user participation.
Why We Chose UGC Creatives: Data and Metrics
Our growth tool analysis showed that simply raising budgets or adding gamification without emotional resonance wouldn’t significantly move the needle. Users needed a clear emotional context proving the app’s value.
The Power of Authentic Stories in Numbers
Our app growth analysis revealed that traditional promotion methods had reached their ceiling. The implementation of UGC content became a turning point that transformed all our key performance indicators. Let's see how authentic stories changed our growth dynamics:
