## What is DQS Mobile?

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.

### 1/5 — Can't even use the app

*2025-11-20, version 5.0.7*

A screen pops up to start a free trial or start a subscription but when I tap on either I get an error that says there's a problem with the configuration in RevenueCat. Frustrating.

### 5/5 — Love this app

*2025-11-13, version 5.0.6*

This is a simple way to eat healthy.

### 5/5 — Really helps with overall health

*2025-09-29, version 5.0.6*

This is a great app and not just for athletes imo. If you were to just use this app and nothing else, and aim for a high score 90% of the time, I believe it would transform your health. No calorie counting etc. It incentivises you to eat a varied and healthy diet while still having treats just not too many. When I have a high score I feel great in myself - more energy, better mental health, less aches and pain etc. It's not rocket science but this is a great way to measure your diet in a holistic way without getting obsessed with it or feeling deprived

### 3/5 — Very buggy

*2025-06-15, version 3.3*

I like the approach to nutrition that this app promotes, but it is a bit buggy on my phone. I am unable to change days in the app without fully quitting and restarting. I’d love a modern version with just a few more features.

### 5/5 — Simple but effective

*2025-05-18, version 3.3*

I’m not a fan of counting calories and getting stuck in the weeds so I’ve found this app and Matt Fitzgerald’s books about nutrition.

### 4/5 — Works great

*2025-01-22, version 3.3*

Useful app for athletes that are familiar with the DQS and want assistance with tracking consumption.

### 5/5 — Awesome app!

*2024-10-29, version 3.3*

I use this daily. My family does too. It’s simple (meaning people will use it), and has a great focus on quality of foods. It’s less helpful when it comes to quantity. One suggestion that would get this to over 5 stars: include as a data point the ratio of high quality to low quality foods.

### 4/5 — fair app when it works

*2024-10-07, version 3.3*

update: i uninstalled and then reinstalled the app and that seems to have solved the issue. previous review: was unable to log any food, weight, etc

### 5/5 — Great app!

*2024-07-29, version 3.3*

I really enjoy the simplicity of this app. It’s not only easy to use, but the underlying concept makes perfect, common sense. As an endurance runner, I use it to ensure I'm getting enough high-quality food to fuel my runs. It also helps control my weight with no weird, strict, or fad dieting. I wish this simple idea would catch on more, but people seem to think crazy is better.

### 3/5 — Needs an update

*2024-07-01, version 3.3*

I really wish this app would get an update. I love it when it works, but hasn’t been working for some time. :(
