Can't even use the app

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.

Love this app

This is a simple way to eat healthy.

Really helps with overall health

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

Very buggy

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. Iโ€™d love a modern version with just a few more features.

Simple but effective

Iโ€™m not a fan of counting calories and getting stuck in the weeds so Iโ€™ve found this app and Matt Fitzgeraldโ€™s books about nutrition.

FAQ

What is the Diet Quality Score (DQS)?

The Diet Quality Score (DQS) is a system described in Matt Fitzgerald's book, Racing Weight, used to measure the overall quality of an athlete's diet. This app helps you easily calculate your daily DQS by logging the servings of different food categories you consume throughout the day.

How do I use the DQS Mobile app to track my diet?

To track your diet, you simply tap to log servings of each food category you eat. Each tap adjusts the serving size (full, half, or zero). You can tap the category name for explanations of what foods are included. Your daily DQS is displayed in the upper right corner.

Can I track my weight and body fat with this app?

Yes, the app allows you to log your weight and body fat percentage on the Tracking page. It is recommended to log your weight no more than once per week. This data can also be viewed in progress graphs.

What are the subscription options for DQS Mobile?

New users can start with a 7-day free trial. After the trial, there are monthly and annual subscription plans available. The annual plan offers significant savings for committed athletes. Subscriptions automatically renew unless turned off at least 24 hours before the current period ends.

What kind of graphs can I see in the app?

The Graphs page provides visual representations of your progress over time. You can view graphs showing your total DQS, your weight, or your DQS score broken down by specific food categories. Data can be viewed over the last week, month, or year.
