Free Fitness Calculator App
Use this free fitness calculator app to estimate your calories, macros, BMI, body fat percentage, water intake and running pace. It is designed as a simple all-in-one tool for women who want practical fitness numbers without switching between separate calculators.
Which calculator should you use first?
Start with the calorie calculator if your goal is weight loss, toning or maintenance. Then use the macro calculator to estimate protein, carbs and fats. Use BMI and body fat calculators for extra context, water for hydration, and pace for walking or running goals.
Built for everyday training
These calculators are useful for gym training, Pilates, walking, running, strength training and general health goals. They are estimates, but they give you a clear starting point.
Shop Women’s Activewear
Your numbers are only part of the picture. Consistency comes from training in activewear that feels good, supports your body and does not distract you mid-workout.
Fitness Calculator FAQs
Are fitness calculators accurate?
They are estimates. Use them as a starting point, then adjust based on real progress, energy, measurements and training performance.
What is the best calculator for weight loss?
The calorie calculator is the best starting point for weight loss. After that, use the macro calculator to set protein, carbs and fats.
Is BMI enough to measure fitness?
No. BMI does not measure muscle, strength, body shape or fitness level. It is only a basic screening tool.
How often should I recalculate calories?
Recalculate when your weight changes, your training changes, or your progress stalls for several weeks.
Can I add this fitness calculator to my phone home screen?
Yes. Use your browser share menu and choose Add to Home Screen.
