About this app

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.

FEATURES:
- Track daily food servings with simple tap interface
- View detailed explanations for each food category
- Save and track your DQS data indefinitely
- Log weekly weight measurements
- View progress graphs over weeks, months, or years
- Set target weight and DQS goals
- Track DQS scores by specific food categories

HOW IT WORKS:
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.

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.

This app is helpful overall, but there are a couple of obvious improvements that could be made. 1) Add a body fat percentage metric. It's more than a little bit surprising that this is absent, especially in light of the importance given this measurement in the companion book (Racing Weight). 2) More specific guidance regarding how to score particular foods. Tapping on the categories gives general guidelines regarding what is included in each category, but a searchable database of specific foods would be a big plus. For example, I am uncertain how to score cacao powder or gelatin powder that I sometimes add to smoothies... This second feature might be a lot to ask, but the BFP metric shouldn't be a big deal.

For endurance performance, I have found it easy & effective to track the quality (DQS) of my nutrition, as opposed to calorie counting or macro-nutrient counting. The DQS has made me more mindful of eating a variety of quality foods (everything) to enhance my endurance. I think this app would benefit from adding a hydration counter. Hydration is extremely important for endurance. I do not see the value in a subscription. You could just keep track of your own DQS in a diary for free.

Hydration tracking is a feature that we will likely be adding soon. This app is a tool, and if it doesn’t provide enough value making tracking your diet easier and better, then it doesn’t deserve a subscription… I will be working to make sure it does. Having a subscription model helps pay for ongoing server costs and new feature development.

I paid for the app recently, but now when I open the app it forces me to choose a subscription model. If I try the button 'Restore from purchase' then it says no purchase where found. I have a receipt. It says under release notes that people who have paid for the app, should not have to choose a subscription model. When the app did work, then the Profile settings never could load
