Who We Are
FWG Gymrat was born from a passion for fitness and technology. Created by Alessandro Fernandes, a developer and bodybuilding enthusiast, our goal is to democratize access to nutritional calculation tools in a simple, fast, and free way.
We know that starting a diet or workout plan can be confusing — how many calories to eat? How much protein do I need? Our calculators eliminate this complexity, delivering accurate results in seconds.
Our Mission
To make nutrition and physical tracking accessible to everyone, without the need for technical knowledge or paid apps. We believe that quality information is the first step towards a healthier life.
Who is Alessandro Fernandes
I am a web developer with over 21 years of experience in creating digital applications. The idea for FWG Gymrat came about when I realized that many existing macro calculators were too complex or didn't adapt to our users' realities.
Besides Gymrat, I develop other technology projects through FWG Apps — check it out at fwgapps.com.
