A new body-rating app is starting to gain traction with a familiar playbook: UMAX-style scoring, but for fitness.
Ujack launched about 4 months ago and is basically “UMAX for the body.”
Users scan their physique, get an overall score, and see ratings for specific body parts.
They’ve already pulled more than 40 million views across Instagram and YouTube Shorts, but the path wasn’t clean from the start.
On Instagram, they grew through a repeatable “winter arc” series built on funny and weird gym training compilations.
The content blew up, but the app barely appeared, so it looked more like audience building than acquisition.
The actual conversion angle started later on YouTube Shorts, once they began using the app directly inside transformation content.
That’s where the format clicked: body transformation videos with app rating.
“3 year transformation” hit 3M views & 2K comments (23 Dec, 2025).
They also added a pinned-comment app promo on these posts, which made the funnel clearer than the earlier Instagram phase.
They first proved they could get attention in gym content, then layered the product into a format that actually matches the app.
