About Vitals
A free health and fitness calculator platform built for everyone, with a focus on Indian users.
What is Vitals?
Vitals is a free, no-signup health and fitness calculator platform. We built it because most health tools online are either too complicated, behind paywalls, or not relevant to Indian body types, diets, and lifestyles.
Our goal is simple: give everyone instant access to accurate health calculations — whether you want to know your BMI, calculate your daily calorie needs, figure out your ideal protein intake, or track your hydration. No accounts, no fees, no data collection.
What we offer
20+ calculators
BMI, TDEE, BMR, body fat, protein, macros, water intake, heart rate zones and more.
100% free
Every calculator is free to use with no signup, no paywall, and no hidden fees.
Private by design
All calculations happen in your browser. We never see or store your personal data.
India-focused
Includes an India-specific Vitamin D calculator and context relevant to Indian users.
Dark mode
Easy on the eyes with full dark mode support across all pages and calculators.
Mobile friendly
Works smoothly on any device — phone, tablet, or desktop.
Who built this
Vitals was built by Chirayu Mahajan, an independent developer with a passion for health, fitness, and making useful tools accessible to everyone. The idea came from frustration with health calculators that were either cluttered, paywalled, or simply not relevant to Indian body types and lifestyles.
Vitals is a solo project — every calculator, design decision, and line of code is Chirayu's work. If you have feedback, found a bug, or just want to say hello, reach out at vitals.health.in@gmail.com
