Tonight a great idea for Mobile App came into my mind.
An excellent name for it would be something like the HowSweet App or similar.
The essence of the application is as follows.

You give him access to your account of instagram, and select the target user, after, the application algorithm process the profile of the “victim”: he analyzes the preferential color scheme of posts, the number of words in post descriptions, the percentage of hashtags in them from the total number of words, the regularity of posts, the number of subscribers. Based on the received data, the program produces a result – requested user is a “sweet” or not enough.

At the second stage, the program collects anonymous data. Then a cluster analysis is performed, through which several groups of users are identified, which makes it possible to realize the gradation of users by several degrees of “sweetness” .
