How to Use MyFoodFit: Getting the Most From the App

MyFoodFit does one thing and does it well: it tells you whether a specific food is a good choice for your specific health situation. But like any tool, you get more out of it when you understand what it is doing and why.

This is a straightforward guide to setting up, scanning, and interpreting your results.

Setting up your profile

When you first open the app, you build a dietary profile. This is the foundation of everything the app does. The more accurate your profile, the more useful your scores.

You can select from 40 dietary profiles covering:

Health goals: General health, weight management, blood sugar control, heart health, high protein, gut health, microbiome support.

Dietary patterns: Vegan, vegetarian, pescatarian, flexitarian, plant-based.

Medical conditions: Diabetes (blood sugar), IBS (low FODMAP), coeliac disease, kidney disease (CKD), Crohn's/IBD, histamine intolerance, pregnancy.

Allergies: All 14 EU declarable allergens (gluten, dairy, nuts, peanuts, eggs, soy, fish, crustaceans, molluscs, celery, mustard, sesame, lupin, sulphites).

Life stages: Pregnancy, menopause, GLP-1 medication support.

Mental health and neurological: ADHD support, mood support.

Religious dietary laws: Halal (three-tier classification), kosher.

You can select multiple profiles simultaneously. If you are managing diabetes and IBS, select both. If you are vegan with a nut allergy, select both. The scoring engine runs all active profiles in parallel and produces a single combined score.

You can update your profile at any time. Health situations change. Profiles should change with them.

Scanning a product

Point your camera at any barcode on a food product. The app resolves the product through up to eight data sources: our offline database of UK products, local cache, our Supabase database of over 3 million global products, and multiple external food databases.

Once resolved, you see:

A score from 0 to 100. This is your personalised score for this product given your active profiles. The same product will score differently for different people.

A colour band. Green (70-100) means this product works well for you. Upper amber (50-69) means it is broadly fine but with something worth noting: elevated sugar, moderate processing, or a nutritional compromise of some kind. Lower amber (30-49) means the product is nutritionally average or weakly aligned with your profile, and worth swapping when a better option is available. Red (0-29) means there are significant issues for your profile.

A one-liner explanation. A brief, profile-specific message explaining why the product scored the way it did. This might reference protein content, sugar levels, a specific allergen, fibre, or ultra-processing.

Detailed nutrition information. Tap through for the full breakdown: macronutrients, NOVA classification, ingredient list, and any specific flags for your profile.

Understanding the scores

The scores are not a universal quality rating. They are a personal relevance rating. A product that scores 85 for a general health user might score 45 for someone with kidney disease (because of high potassium). A product that scores 30 for a weight management user might score 75 for a high-protein user (same product, different priority).

Green does not mean "eat unlimited quantities." It means the product is nutritionally aligned with your profile. Olive oil scores Green for most profiles, but drinking it by the glass would obviously be unwise. The score evaluates the product's nutritional quality per 100g against your needs. Portion decisions are still yours.

Amber is not a warning, but the two amber bands signal different things. Upper amber (50-69) means the product is perfectly acceptable: you would not be making a mistake buying it, but there may be a better option in the same category. Lower amber (30-49) means the product is weakly aligned with your profile and worth replacing when you can. A supermarket own-brand yoghurt might score lower amber while a higher-protein, lower-sugar alternative scores Green. Both are edible choices. The scoring helps you find the better one when you want to.

Red means something specific. When a product scores Red, the one-liner tells you why. It might be an allergen detection for your profile, extremely high sugar content, a nutritional void (low protein, low fibre, high sugar, ultra-processed), or a specific constraint from one of your medical profiles. Red does not mean "bad food." It means "this product has a specific issue for someone with your profile."

Using Find Food

Beyond barcode scanning, you can search for foods using natural language. Type "high protein breakfast" or "low sugar snacks" or "iron-rich foods for pregnancy" and the app uses AI-powered intent parsing to understand what you are looking for, then searches our database and scores the results against your profile.

Results are ordered by score, so the top suggestions are the ones that best match both your search intent and your dietary profile. This is useful for meal planning, discovering new products, and finding alternatives when your usual choices are out of stock.

Scanning tips for best results

Scan in the supermarket, not just at home. The app is most valuable at the point of purchase, when you are deciding between two or three options. Scanning at home tells you about products you have already bought. Scanning in the aisle helps you make better choices before you commit.

Compare similar products. The scoring is most useful when you compare within a category. Scanning five different yoghurts and comparing their scores tells you which one works best for your profile. Comparing a yoghurt to a steak is less meaningful because they serve different dietary functions.

Check products you buy regularly. You might be surprised. Products you have bought for years might score differently from what you expect once your specific health conditions are factored in. This is not the app being wrong. It is the app applying constraints that generic labels cannot show.

Use it for new products. When a new product catches your eye, scan it before it goes in the trolley. The colourful packaging and health claims on the front are marketing. The score is based on what is actually inside.

What the app does not do

It does not replace medical advice. If you have a diagnosed condition, work with your healthcare team on your dietary plan. The app provides decision support at the point of purchase, not clinical guidance.

It does not track calories or macros. MyFoodFit is not a food diary or calorie counter. It is a product evaluation tool. If you want detailed nutritional tracking, use it alongside a tracking app. They solve different problems.

It does not gamify your food choices. There are no streaks, no scores-of-the-day, no leaderboards. Food is personal and often complicated. We built the app to inform, not to judge.

It does not sell your data. Scanning data is anonymised. We collect behavioural signals to improve the product, but these are linked to anonymous device identifiers, not to your personal information.

Getting the most from MyFoodFit

Start by scanning the products already in your kitchen. This gives you a baseline understanding of how your current diet scores against your profile. Then, next time you shop, scan one or two alternatives in each category and see if there are easy swaps that improve your scores without changing what you eat dramatically.

The biggest improvements come not from overhauling your entire diet overnight, but from making slightly better choices consistently. A Greek yoghurt instead of a flavoured one. Brown rice instead of white. A different brand of bread that happens to have more fibre and less salt. These small shifts, repeated daily, compound into meaningful health improvements over weeks and months.

That is what the app is for. Not perfection. Just better information, one scan at a time.
