Eat better
Scan a product for its overall nutritional quality, or photograph your plate to see how the meal fits your day's remaining budget.
Organize your meals
Save favorite meals, plan your days and prepare shopping lists without entering the same foods again.
See your progress
Track your weight, its 7-day trend and your consistency to understand the real trajectory.
Snap a photo. It's counted.
The AI identifies the foods on your plate, estimates portions in grams and calculates calories and macros — all adjustable with one tap. The meal gets its own score out of 100 based on your goal, portion, meal time and remaining calorie/macro budget, with an actionable tip.
Two scans, two questions.
A barcode rates the product's overall quality. A meal photo rates how it fits your day based on your goal, portion, meal time and remaining calorie/macro budget. Never a black box.
- Transparent reasonsThe impact of every factor, in points: “Very sugary −20”, “High in protein +12”.
- Additives decodedEvery E-number rated from EFSA / WHO opinions.
- Allergen and diet alerts14 EU allergens. Vegetarian, vegan, pescatarian, halal.
Your whole day. One single app.
The scan is just the front door. Behind it, a complete journal keeps track of your day: your macros calculated from your profile, your meals logged in one tap, and everything that builds consistency.
Calories, protein, carbs, fats — calculated from your profile, not from averages.
Your usual breakfast logs in one click.
A catalog filtered by diet and allergens, with the macros already counted.
Generated from your recipes, ready for the store.
Curve smoothed over 7 days — the real trajectory, not the zigzag.
Consistency made visible: your streak of days, your water, your steps.
Results you can actually see.
A single number tells you nothing. ZymFit smooths daily changes and places every weigh-in in your trajectory. See the direction, not the noise.
- 7-day trendA clearer curve than the scale's raw daily changes.
- Goal always visibleYour starting point, target and distance already covered.
- Encouraging consistencyYour streak rewards small repeated actions without guilt.
You choose 2 to 4 products; ZymFit compares their overall quality and explains the ranking.
Two products. One winner.
At the shelf, scan both. ZymFit compares their overall nutritional quality and tells you which to keep. No more hesitating at the supermarket.
Public data. A visible calculation.
A rating only matters if you can verify it. ZymFit draws on reference databases — and shows you every factor behind the calculation.
“Every factor in the score is shown — sugars, protein, additives rated per EFSA and WHO. Never a black box.”
Every screen, in your language.

Questions? We’ve got answers.
What’s the difference with Yuka or the Nutri-Score?
A barcode scan gives an overall nutritional-quality score that stays the same whatever your goal. It follows a transparent formula: 60% nutritional quality, 30% additives and 10% organic certification. NOVA remains visible separately and does not change the score. A meal score answers a different question: does this portion, at this meal time, fit your goal and remaining calorie/macro budget?
Is ZymFit really free?
Yes: free access has no time limit and requires no card — 7 barcode scans per week and 3 meal photo analyses per week, journal and saved meals, weight tracking and unlimited meal history. Pro is the only optional subscription — no commitment, cancelable anytime.
How does the photo scan work?
A photo of your plate is enough: the AI identifies the foods and estimates portions in grams, then calculates calories and macros — adjustable before saving. The meal then gets its own score out of 100, with an actionable tip.
Where does the nutrition data come from?
From three public databases: ANSES-Ciqual (3,000+ verified generic foods, translated into 7 languages), Open Food Facts (3M+ barcode products) and USDA FoodData Central. The product score assigns 60% to nutritional quality, 30% to additives and 10% to organic certification; NOVA remains separate information. Meal fit also uses the portion and your day's remaining budget.
Do you need a subscription to use the app?
No. The download and free access remain available indefinitely without a card. Pro, at €4.99/month or €39.99/year, is optional and unlocks unlimited barcode scans and up to 8 meal photo analyses per day.
How do I cancel my subscription?
Cancellation is done from your App Store or Google Play account settings, not in the app. Canceled before the end of the current period, no additional charge is taken, and the account automatically switches back to Free with no data loss.
