Introducing Fuel Coach, the cutting-edge app that makes personalized endurance sport nutrition easy. Confused about glucose:fructose ratios, how much carbohydrate you need for that marathon, whether you really need salt tabs or not, wondering how isotonic your drink mix is? Struggling to find nutrition products that don't make you ill while doing endurance sports or curious about mixing your own fuel? Fuel Coach takes the guesswork out of understanding your nutritional needs, ensuring you optimize performance while avoiding dehydration, maintain blood plasma sodium concentration, and minimize the risk of consuming fuel that could make you sick. Powered by research from the worlds leading sports scientists, Fuel Coach calculates your individual requirements for carbohydrates, water, and sodium. Tailored to your sweat rate, sodium loss rate, athletic ability, and activity details, these scientifically-backed guidelines will help maximize your athletic performance to reach your full potential. Once you've calculated nutritional needs the app will guide you through building fuel to meet those requirements using commercial gels and powders ... or from salt, sugar, water from your kitchen! The built-in coach function will guide you throughout the process. Coach will offer valuable tips to ensure you make informed decisions, help understand where there might be issues, explain nutrition concepts, break down what's in commercial products ... It's like having a personal sports nutritionist in the palm of your hand, guiding you towards success. Oh, and, want to do all this with an app that looks like it was made by space pirates from the 1980's? Or prefer a stripped-down aesthetic? There are a bunch of themes to choose from, just like nutrition recommendations - tailor it for you! Also, there's a boombox. Enjoy!
