“A screen-recording hook you can use to sell a health & fitness app - scroll-showing a period calendar crowded with intimacy hearts to joke about moving in with a boyfriend.”

This app demo TikTok post pulled 1.2M views - 945× what the account typically does (~1.3K 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 (20.2% 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: Musa, a period and cycle-tracking app.
