For months we’ve been tracking GoTall, the height‑analysis app that quietly grows through niche formats.
This week we found a creator who finally cracked a structure capable of generating tens of thousands of comments in a single video.
The creator uses a slideshow format, but the real engine is the hook.
Instead of directly asking viewers to comment their height and weight, he frames it as a challenge:
“flex your height with your age”
It’s a subtle psychological trick: he’s not asking for comments, he’s inviting people to show off.
And because he shares his own height and age first, pulled directly from the GoTall app, viewers feel encouraged to follow.
The result: 38.6K comments on a single video.
