You're managing app campaigns for a tax services software company. Which of the following assets should you use?

The most effective asset for an app campaign promoting tax software is a screen-capture video demonstrating the app's functionality. This directly shows users how the app works to solve their tax-filing needs, building trust and illustrating value. An image of someone holding a phone with the app on-screen is too generic and doesn't convey the app's utility. A headline with just the app name and a call-to-action lacks visual engagement and doesn't explain the app's purpose. While a video telling a complete story can be engaging, a direct screen-capture showcasing the core functionality of filling out a tax return is more practical and persuasive for an app designed for a specific task.
