How crucial is it for a startup to have a descriptive video showcasing their product or service?

Hey fellow hackers,

I'm thrilled to announce my upcoming startup launch—a mobile app! I'm curious about the importance of having a descriptive video on the app store and other promotional platforms. As I submit JudgeUs to different websites and engage in social media efforts, I'd love to hear your experiences and examples of how videos have boosted user interest.
