The app allows customization of inputs such as name, gender, eye color, and current age, enhancing the personalization of the experience.

The application emphasizes privacy by securely storing all images on the user's device, ensuring that no photos are saved on external servers. With a user-friendly interface and a variety of photography styles and scenes, "When They Grow Up" delivers high-quality AI-generated images. While the app is free to download, a premium experience offering additional images is available at a discounted price for a limited time.
