This is the official Racing Weight Diet Quality Score App, now with the ability to save your DQS data for as long as you want and view graphs of your progress over time!

This app allows you to calculate your daily Diet Quality Score (DQS) as described in Matt Fitzgerald's book, Racing Weight.

The Diet Quality Score is a simple instrument that allows athletes to measure the overall quality of their diet. The DQS Mobile app was designed to make it as easy as possible to calculate a Diet Quality Score each day.

As you eat throughout the day, enter the servings of each category of food that you consume. Tap a box to consume one serving of that category, tap it again and it will become a half serving, and one more tap will set it back to zero for that box. You can tap the category name to view an explanation of what foods fall under that category. Your total DQS score for the day is shown in the upper right corner of the page. DQS data is saved for each day you track it.

You can also log your weight on the bottom of the Tracking page. We recommend you log your weight no more than once per week.

The Graphs page lets you see how you are doing with your Diet Quality Score over time. You can view your data over the last week, month or year. When viewing yearly data, it is displayed as 52 week-long averages. You can view graphs showing your total DQS, your weight, or your DQS score by specific category.

You can set a target weight and a target DQS score on the Profile page.

Uncomplicated diet quality improvement app

In a world of monotonous calorie tracking & chasing exercise calories to out train poor diet choices this app is a breath of fresh air, it’s straightforward, easy to use and a perfect compliment to Matt Fitzgerald’s Racing Weight book series.

I’m making better food choices, going to the gym more and steadily increasing my lean mass & reducing body-fat.

If I was to improve the app I’d add body-fat & lean mass measuring so they can be graphed along with DQS, that aside, great app & good value.

Great for endurance athletes

What I like about the DQS from "Racing Weight" is it is a simple way of tracking diet quality, without worrying about macros, logging everything etc. I keep coming back to this app every training cycle and it makes a real difference in leaning me out and improving recovery
