Flower store app. Does it make sense?

I'll try to be brief.

There's a store in New York that sells and delivers flowers: https://saholaflowers.com. The owner asked an off-topic question: would an app, in addition to a website, make sense?

And I'm a bit stumped: usually the client doesn't ask "does it make sense", usually the client says "do this or this for me".

I decided to experiment with chatGPT again: what could it tell me about it?

I won't give you the whole correspondence, I will only summarize my conclusions: the chat offered to analyze whether this application would be relevant? That's a good point, but that's exactly the question I asked the chat!

Thus, for now, my question remains unanswered.
