Hi, I'm Karthik 👋

I started building KFit because I was tired of bloated fitness apps demanding $80 a year just to scan a barcode or view a protein breakdown. Even worse, standard apps sell your intimate health metrics and fail completely on authentic Indian food.

I wanted an experience that felt like writing in Apple Notes — lightning-fast, impeccably crafted, and respectful of your privacy. With KFit, KFit Web, GymWorld, and JARVIS, my goal is simple: deliver elite, private athletic software without venture capital greed, subscriptions, or paywalls.
