Try it: yournumber.herokuapp.com
This is a fitness app built mostly with Angularjs, which allows you to figure out your macronutrient ratio and numbers that you need to be getting every day to achieve your fitness goal.
I am a Certified Personal Trainer and I used formulas such as the Harris-Benedict Metabolic Rate equation to help figure out the numbers. Nonetheless, this app is still in development so please know it is subject to bugs! If the numbers you are seeing don't make sense, especially if you have crunched numbers more than once per page reload, please reload the page to reset to normal behavior. Improvements are in progress.
