“A heartbreak-revenge slideshow you can use to grow a health & fitness app - it opens with an emotional relationship hook over gym footage before revealing the tracker interface.”

This slideshow TikTok post pulled 13K views - 9× what the account typically does (~1.5K views on a normal post). That gap is what Handler calls an outlier: the breakout came from the content's structure, not the account's size.

Engagement pull sits at 5/5 (26.2% weighted), measuring how hard the post moved viewers to save, share, and comment - the actions that signal real intent, weighted heaviest. The product behind it: A calorie and macro tracking app.
