About
Who builds FitRay, and how
FitRay is an independent fitness app — training, nutrition and coaching in one place, in English, German, French, Arabic and Persian. This page is about who stands behind it, where the numbers come from, and what we will not claim.
The product
FitRay is built and maintained by a small independent team. It is published by a company registered in Dubai, United Arab Emirates.
We are not a clinic, a supplement brand or a media site. Advertising pays for the free tier — it never changes a nutrition value, an exercise instruction, or the order in which coaches and nutritionists appear.
How the exercise library is built
Every movement carries the same fields: the muscles it works split into target, secondary and tertiary, step-by-step instructions, the equipment it needs, and a difficulty level. Because the fields are identical across the library, two exercises can be compared directly instead of by reading prose.
The library was written for FitRay. It is not imported from a third-party database — which means no licence is attached to it, and no other product's mistakes are inside it.
What we do not claim
FitRay is a self-tracking and information tool. It is not a medical device, and nothing in it is medical advice. Calorie targets, macro splits, workout templates and coach-supplied plans are all information, not prescription.
Nutrition values are estimates and differ between brands, cuts, growing conditions and preparation. Do not rely on them to manage a medical condition — diabetes, allergies and intolerances included. Always check the product's own label.
Coaches and nutritionists listed on FitRay are independent third parties. We verify listing details, not clinical competence, and we are not party to the advice they give you.
No exercise or meal in FitRay has been reviewed by a named clinician. When that changes, this page will name the person and their credentials — until then, we would rather say so than imply otherwise.
Languages
English, German, French, Arabic and Persian — and not only the interface. Every food and every exercise is translated, so a reader in Riyadh sees the same catalogue as a reader in London, in their own language.
The nutrition data, measured
Every nutrition database is an estimate, so rather than assert ours was accurate we measured it. In August 2026 the ingredient catalogue was compared, item by item, against USDA FoodData Central (SR Legacy) — a public-domain reference maintained by the U.S. Department of Agriculture.
- Reference
- USDA FoodData Central, SR Legacy
- Foods compared
- 731 confident matches
- Median calorie deviation
- 0.0%
- Within 5% of the reference
- 77%
- Within 20% of the reference
- 90%
- Median protein / carb / fat deviation
- 1.0% / 0.6% / 1.2%
Only single ingredients were compared, not prepared dishes: a dish changes with its recipe, so a difference there would say nothing about data quality.
The values that remain furthest from the reference are the ones most dependent on brand and preparation — sauces, condiments and drinks. If you find a number that looks wrong, tell us. Corrections are the fastest way this improves.
