Advanced methods for the best posts?

Hey so there was an app/software here on BHW that I couldn't find anymore that had this algorithm or something that let you find the best viral posts for your niche, based on things like how many likes did it get in short time etc. etc.

Basically I'm looking to find the best possible content for my accs; where should I find and what advanced techniques do you propose?

With automation tools like Jarvee or any other?

I know of looking for best performing posts of each acc (bigger accs in my niche) but any other ideas?
Thanks
