Why We Built Calorie Calculator 24
Fitness and nutrition should be accessible, scientific, and beautiful. Most health tools on the web are either ancient, cluttered with ads, or hidden behind aggressive paywalls and sign-up forms.
Calorie Calculator 24 was born from a simple idea: Create a premium, friction-less tool that gives you the exact data you need to master your 24-hour energy cycle in under 30 seconds.
No Data Storage
Your personal health data is yours alone. We don't save it, we don't sell it, and we don't even see it.
Science-Backed
We skip the "miracle" formulas and stick to the Mifflin-St Jeor equation—the industry standard for accuracy.
