How to export contents (blog posts) differently into another Application

Hello, i am a newbie to ghost and i would like to know if this idea i have is doable.
We have a mobile application which we are developing for our clients. In that mobile app, we will have mini apps running in it. Then we want to start a blogging site for our company and we want certain information from the blog to appear in the mini apps. But this information SHOULD DISPLAY ONLY the post designated, without the Header section nor footer section, nor any other post. At the same time, outside the APP, the normal theme appearance is not altered.
Is that possible? If Yes, how do we proceed?
Thanks
