Yim Yoon-seok, a pharmacist and bodybuilding nutrition coach, used the Manus AI agent to build a fitness tracking web application called Alyak Coach without any prior coding experience. The app features an AI-powered TDEE calculator that adapts weekly based on user data, and within two months it grew to around 300 active users, later reaching 3,900 registered users and generating revenue. An external developer had estimated the project would require six months of full-time work, but Yoon-seok built it in weeks using Manus.

## Evidence

Verbatim from https://manus.im/blog/alyak-tv:

> He found Manus through an internet advertisement in mid-February. It was his first encounter with an AI agent, a system that could write and deploy code on his behalf. He decided to try building the app himself.
