What is the difference between iMessage and you message?

Could you please clarify the distinction between iMessage and "you message"? As far as I'm aware, "you message" isn't a widely recognized messaging platform, whereas iMessage is a messaging service provided by Apple that allows users to send text, photos, videos, and other content over Wi-Fi or cellular data to other Apple devices. Are you perhaps referring to a specific messaging app or service that you're comparing to iMessage? If so, could you provide more information about that service so that I can give you an accurate answer?
