Nutrition tools case study

Kalorienhilfe

A standalone web app for calorie calculators, BMI, macros, and nutrition content.

Kalorienhilfe.de is a separate web project and is no longer embedded as a full app inside this portfolio codebase. This page documents it as a case study: calculators, structured food tables, guide content, and SEO-focused information architecture.

Project overview

From quick calculators to a focused nutrition platform

The focus was a clear, low-friction experience for people who want to assess calorie needs, deficits, BMI, macronutrients, or activity expenditure quickly. The content is structured so calculators, tables, and guides support each other.

Role / implementation

Concept and implementation of the web app including information architecture, calculator interfaces, content structure, responsive UI, technical SEO foundations, and deployment. In the portfolio, Kalorienhilfe remains as a case study while the production app runs separately.

Outcome

The result is a standalone public platform for simple calorie and nutrition tools. Separating it from the portfolio reduces maintenance overhead and keeps the project presentation clear without embedding the full app again.
