The Team

Two developers and a three-person documentation team responsible for clinical, API, and user-facing docs.

Builder's Note

"We built FitFusion360 because generic fitness apps wanted users to fail so they can sell subscriptions. This is the tool everyone needs: blunt, effective, and scientifically grounded with references like Mifflin‑St Jeor, ISSN protein guidelines, and Hall's energy deficit research."
