Health and fitness calculators turn personal numbers into planning estimates. They are useful for setting targets, but they are not a diagnosis or medical advice.

BMI Calculator

Body mass index and healthy weight range, metric or imperial.

Calorie & TDEE Calculator

Daily calorie needs from BMR and activity (Mifflin-St Jeor).

Macro Calculator

Split daily calories into protein, carbs and fat grams.

Body Fat Calculator

Estimate body-fat percentage with the US Navy method.

Ideal Weight Calculator

Target weight range by height with Devine and Robinson formulas.

Water Intake Calculator

How much water to drink a day by weight, activity and climate.

Choosing the right tool

Use calorie, macro and hydration tools as starting estimates.
Use pace and heart-rate tools for training planning.
Check with a professional for medical conditions, injuries or major diet changes.

Before you start

Open the tool page, read the short limits section, then run a small file or simple example first. That keeps the job predictable and makes the final download easier to trust.

Common Health & Fitness questions

Are Health & Fitness tools private?

Most Vootkit tools run in your browser, and each individual page says when a tool needs a network request. Files handled locally never leave your device.

Do I need to install anything?

No. Vootkit tools are built for modern browsers, so you can open the page, complete the task and download the result without installing desktop software.

Why do some tools say coming soon?

Vootkit keeps planned tools visible for roadmap context, but they are not presented as finished features. Live tools have working pages and are included in the sitemap.
