A fitness calculator is an interactive tool that lets website visitors track their wellness goals. From calculating BMI (Body Mass Index) and basal metabolic rate (BMR) to tracking weight gain or daily calorie intake, you can use them to keep your online community healthy, motivated, and coming back to your website.

We'll give our calculator form a name, then click Create to start building or customizing.

Here, we can add the fields we want to our form by dragging and dropping them from the left to the right of the builder. For example, you may want to add fields for body weight, age, body fat percentage, and physical activity level to make a fitness age calculator.
