The heatmap seems to be the most unique part of your application, so I would actually recommend focusing solely on that feature. The idea is quite interesting, actually. While I know what a heatmap looks like, I am curious to know more about how exactly it will be employed / visualized within your application.
While they are certainly purposeful and respond to clear problems, I think the other features you have mentioned are not as unique. If you plan to still prototype these features, I would suggest trying to better articulate how they are different from existing apps, what more they provide, etc.
I look forward to seeing your outcome!
