Add a block on WP
90 USD Technical task: develop and implement a calorie counting calculator on the website with BMR calculation using the Mifflin–St Jeor formula, TDEE based on activity level, and recommendations for daily macronutrient distribution (proteins/fats/carbohydrates) depending on the user's goal (weight loss, maintenance, gain). The interface should include fields: gender, age, height (cm), weight (kg), activity level, goal, and optionally, the percentage of deficit/surplus; support a unit switch (kg/lbs, cm/inches) with instant conversion. Ensure input validation, hints, accessibility (label/aria, focus states), localization UA/RU, responsive design, and display results in a clear block with BMR, TDEE, recommended calorie intake, and macro scheme (for example 30/30/40 with the ability to change proportions). Implement as a standalone component (React) with the ability to embed on any page, saving the last parameters in localStorage, copying results to clipboard, and optional export to PDF. Provide a modular structure for further addition of formulas (Harris–Benedict, Katch–McArdle), unit tests for formulas and validation, event analytics (sending/changing parameters), a banner with the disclaimer "not medical advice," and SEO data settings (schema.org/SoftwareApplication). Result: a ready component with integration documentation, a list of props/settings, localization instructions, and styles.

I will implement a modern and responsive calorie calculator on WordPress in the form of a standalone React component for you. It will take into account BMR using the Mifflin–St Jeor formula, calculate TDEE based on activity level, and provide recommendations for calorie intake and macronutrient distribution depending on the user's goal. The calculator will have a user-friendly interface with a unit switcher, hints, validation, support for UA/RU, the ability to copy results, and export to PDF. Accessibility will also be ensured (aria labels, focus states), a modular structure for further expansion, event analytics, and SEO settings. You will receive a ready-made block with integration documentation, a list of settings, and a flexible design for any page of the site.
