Why it worked
The video leverages a common user experience (discovering new app features) and seamlessly integrates a product promotion through the creator's bio link and app demonstration, making it feel like a helpful tip rather than a direct advertisement.
Summary
The creator shows a TikTok video demonstrating a workout routine and then transitions to showing the Zeno app, which appears to be a fitness and habit tracking application. The creator's bio link also directs to the Zeno app, indicating it is the product being promoted.
