Ask HN: Here are 40 app DL codes. How can I grow my iPhone app?

I am trying to grow my business, I have a lot of product ideas that revolve around AI / human computer interaction and this is the first app I have released that starts to dip into that space. Would people even use this? Yes, some people have payed for it, but I want to take it to the next level. Customers don't seem to comment on it or email me feature requests. What do you think?
