I'm getting it from the fact that you aren't showing people a job posting. Nor are you asking about their experience. Your application process is to send you ideas for growth. That is why it sounds like free consulting.
I know the kind of person you are looking for. I am that type of person. And I'm telling you there is no way I'd download an app and send my ideas in as part of a job application. I'd gladly do so as a small paid gig during the application process, when we have talked and it feels like my experience matches your needs. But not as the initial contact, no way.
