I just launched FitWizard.in — Free AI Workout Plans and Macro Calculator built solo with Flask

Hey Indie Hackers 👋

I'm Subramanya, a solo developer from Bengaluru,

India. I just launched my first web app — FitWizard.in

━━━━━━━━━━━━━━━━━━━

🤔 The Problem

━━━━━━━━━━━━━━━━━━━

Most fitness apps either:

- Charge monthly fees for basic workout plans

- Force you to create an account just to see anything

- Give generic plans that don't match your body or goal

I was personally frustrated by this so I decided

to build a free alternative.
