Health & Fitness Calculators Suite

Health & Fitness Calculators Suite is a WordPress plugin designed to enhance fitness sections of websites by providing a suite of scientific health calculators. It addresses the needs of fitness professionals, nutritionists, gyms, and wellness-focused sites seeking to engage visitors with interactive tools while supporting lead generation and monetization strategies.

The plugin offers both a free and a Pro version. The free version includes two calculators: a BMI (Body Mass Index) calculator featuring a color-coded visual scale and customizable information accordions, and a BMR & TDEE calculator for estimating basal metabolic rate and daily calorie expenditure using Mifflin-St Jeor and Harris-Benedict formulas. These calculators can be embedded via Gutenberg blocks, Elementor widgets, or shortcodes. The Pro version unlocks seven additional calculators: body fat percentage (US Navy method), ideal weight bounds (Robinson, Miller, Devine, Hamwi equations), daily water intake, lean body mass (Boer and James formulas), target heart rate zones (Karvonen formula), one-rep max (Epley, Brzycki, Lombardi formulas), and pregnancy weight gain guidance based on pre-pregnancy BMI.

For monetization, the Pro version includes a Conditional Product Recommendations feature that displays specific WooCommerce products or custom HTML/shortcode blocks based on users’ calculated categories, such as suggesting muscle building plans for underweight users or fat loss programs for those classified as obese. Advanced lead generation capabilities in Pro allow site owners to capture names and emails before showing results, sync leads in real-time with Mailchimp, MailerLite, or Brevo, or manage and export leads locally in CSV/XML formats.

Additional Pro features include interactive animated SVG charts, branded PDF report downloads, advanced macronutrient splits for diet planning, and extensive customization options for colors, sliders, borders, and labels directly from the WordPress admin panel. The plugin supports full integration with Gutenberg and Elementor, offering blocks and widgets for each calculator. Licensing options include a free version with updates via the WordPress repository and a Pro version with dedicated support and automatic updates.
