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 and body fat % 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, body fat % and a target DQS score on the Profile page.

Working again and back to being great

I used this app all the time. I really liked it and found it very valuable. Since the most recent iOS update it no longer works. I tried sending a message to the developer first, but I did not receive a response. I hope it gets updated since I paid for it and would like to continue using it. Would change review to 5 stars if it returns to its previous functionality.

Update: after not working for a vm couple weeks it now works again. As I stated, back to a 5 star review. Not sure what the problem was but I think it is a great app.

Like it a lot, a few additional features would make it even better

Love the simplicity and ease of use for tracking daily diet quality! There are two things I would change to make it just a little better:

1. I wish that I could have it in vegetarian or vegan mode one day, and then omnivore the next. I do eat meat, but not every day, so sometimes I'd like to score my legumes as a protein, for example. Currently, the app will only allow you to be in one mode for all days, so if you switch to veg mode, all of your days switch over to that mode.

2. I wish there was a place to put notes about the day - just a small field that I could fill in something I felt was important. For example, on weeks that my training load is reduced and I'm eating less in general (and therefore getting seemingly lower DQS scores), it'd be nice to have that noted so that when I look back I remember that detail.

Basic but useful especially for RW users

I have gone back and forth between this tool and full-featured calorie counter apps. I've decided to stick with this one. If you are bought into the Matt Fitzgerald system, as I am, this is a simple tool to ensure as many of your nutritional choices throughout the day conform to his Racing Weight/Endurance diet as possible. When I was 30 pounds away from my target weight, calorie counting made more sense. I needed that kind of data proof that my food choices could make a big impact. I don't need to be convinced of that anymore. This app, despite its limitations, keeps me on the straight and narrow in a very simple way. It does not demand much of a time or memory commitment on my part. DQS scoring, once you get the hang of it, is instinctual. In short, it works.

The only change I would make is having it report back to the health app that comes with the iPhone.
