In shortAirTuner (Timber Apps) wanted more app installs and ROAS in the US. We produced UGC testimonials with different opening hooks, delivered in 3 business days, then scaled the winner to new markets: +100% CTR, +120% sales lift and 45% higher CVR.

When it comes to user acquisition, grabbing attention in the first three seconds can make or break your campaign. AirTuner (Timber Apps), a platform offering access to thousands of live radio stations, wanted to boost their return on ad spend (ROAS) and app installs across the US market. The challenge? Standing out in a crowded app ecosystem and moving beyond generic AI ads.

At Wizads, we knew the solution was to lean into authenticity with user-generated content (UGC) and a rigorous approach to creative testing.

The Approach

🎯 Hook A/B Testing

We started by producing a series of UGC testimonial videos—reels and stories—each featuring a different opening hook. From eye-catching statements (“You won’t believe this app exists…”) to problem-solving intros, our goal was to see what would make viewers stop scrolling.

To evaluate performance, we measured:

  • Early engagement (3-second views)
  • Click-through rates (CTR)
  • Conversion rates (CVR)

⚡ Rapid Iteration

Speed was essential. We kept turnaround to three business days from brief to delivery. Using a female US-English creator ensured the content resonated with the target audience, replacing the less effective AI-generated ads.

🌎 Scale and Adapt

Once we identified the top-performing hook, we scaled it quickly. The winning creative was translated and adapted for other English-speaking markets and new language regions to maximize impact.

The Results

The outcomes exceeded expectations:

✅ +100% CTR compared to prior paid creatives
✅ +120% Sales Lift in US campaigns
✅ 45% higher CVR than any creative from the past year

The campaign demonstrated that authentic, well-tested hooks are the key to unlocking performance in modern paid social.

Key Takeaways for Brands

  • Test More Hooks Early: Don’t guess what will resonate. Test multiple hooks and let the data decide.
  • Move Fast: Creative fatigue sets in quickly. Rapid iteration keeps campaigns fresh.
  • Authenticity Wins: UGC outperforms polished, scripted ads, especially in app installs.
