An app that allows you to send an anonymous text to your friend if you see them doing something embarrassing

Would probably work as a widget on mobile. You would put the persons number and name in the app, and then add a list of phrases you would commonly wish to send to them. IE “I love you” for a significant other, “I’m really proud of you” for a child, or just “I love you” for a child too in a way, but in a different way, but it definitely applies. For a friend it would be more of embarrassing phrases, and for a relative it could be phrases that would embarrass you, or them, or both, but you would be too polite to say them in person. Like “I think a great gift would be sending you to your room for an hour.”
