How food logging works

0xCal: photo, chat, and barcode

0xCal uses AI to log meals from three inputs: photos, natural language text, and barcode scanning. Snap a picture of your plate and get calorie and macro estimates in seconds, type what you ate in plain English like "chicken stir fry with rice", or scan a packaged product's barcode. The AI parses your input, estimates portions, and returns a full macro breakdown without requiring you to search a database, pick serving sizes, or assemble recipes manually.

This approach is especially strong for homemade meals, restaurant dishes, and international cuisine — foods that rarely have an exact match in any database. You describe what you ate, and the AI does the rest.

Fitatu: database search and barcode scan

Fitatu uses a curated food database combined with user-submitted entries. You search for a food item, select the best match from the results list, and adjust the serving size. For packaged products, the barcode scanner pulls nutrition data automatically.

Fitatu's database is well-maintained and particularly strong for European foods and brands — it has better coverage of Polish, German, and other regional products than many competitors. However, like any database-driven tracker, it struggles when the food you ate doesn't match an existing entry: homemade meals need to be built ingredient by ingredient, and restaurant dishes outside of major chains often have no match.

Accuracy

We run a weekly benchmark testing 72 foods — from everyday staples to complex homemade meals, restaurant dishes, international cuisine, and intentionally misspelled inputs — against USDA reference data from FoodData Central.

0xCal's AI approach shows the largest advantage with complex meals where a single database entry cannot capture the full picture. A "loaded baked potato with butter, sour cream, cheese, and bacon bits" has five components — the AI reasons about each one. In Fitatu, you would need to find a matching entry (which may be for a plain baked potato) or build a custom recipe.

For typos and misspellings — inputs like "mackdonal chiken nugits" or "breckfast bureto with eg and cheez" — Fitatu returns zero results because it relies on text matching against its database. 0xCal's AI understands the intent behind messy input and returns accurate estimates regardless of spelling.

User experience and design

0xCal is built as a native iOS app with a dark, minimal interface. There are no ads, no social features, and no bloated screens. The app is focused on one thing: fast, frictionless food logging with a premium feel.

Fitatu has a clean, colorful design that is more approachable than many calorie trackers. It includes meal planning features, water tracking, recipe building, and shopping lists. The free tier includes ads, but the overall UI is less cluttered than some competitors. Fitatu also supports multiple languages natively, making it a strong choice for non-English-speaking users across Europe.

Handling real-world food

Homemade meals

Fitatu's recipe builder lets you assemble meals from individual ingredients, which is thorough but time-consuming. For a "breakfast burrito with scrambled eggs, cheese, bacon, and salsa" you would need to add each component separately and specify quantities. In 0xCal, you describe the whole meal in one sentence and get an estimate in seconds.

Restaurant meals

Fitatu's database covers some restaurant chains, but local restaurants, independent cafes, and most non-chain dining options have no entries. 0xCal handles these by reasoning about the dish from its description — "chicken fettuccine alfredo from a restaurant" gets a full breakdown based on typical preparation and portion sizes.

International cuisine

Fitatu has notably better coverage of European cuisine than most trackers, thanks to its Polish and European user base contributing regional foods. However, for global dishes like ramen, bibimbap, chicken katsu curry, or falafel wraps, database results can still vary significantly. 0xCal's AI normalizes these into consistent estimates based on standard recipes and portions.

Privacy

0xCal processes food data through AI but does not store meal photos or health data on its servers. Apple Health data stays on device. The app has no social features, no user profiles, and no advertising SDKs. See the full privacy policy.

Fitatu requires account creation and stores food diary data on its servers for cross-device sync. The free tier includes advertising, which involves third-party tracking SDKs.

Pricing

Fitatu offers a functional free tier with ads. Premium removes ads and unlocks features like shopping lists, meal selection, and expanded intermittent fasting options. The newer Premium+AI tier adds AI-powered photo calorie estimation. Pricing varies by region — Fitatu is typically more affordable in European markets. 0xCal offers a free trial with all features, then requires a subscription — no free tier, but no tiered feature gating either.

Where Fitatu wins

Fitatu has genuine strengths that are worth acknowledging:

• European food coverage — Fitatu has the best database for Polish, German, and other European regional brands and products. If you live in Europe and eat local packaged foods, Fitatu's database will have better matches.
• Multi-language support — Fitatu is fully localized in Polish, German, Spanish, Portuguese, and more. 0xCal currently supports English only.
• Cross-platform — Fitatu works on both iPhone and Android. 0xCal is iOS only.
• Free tier — Fitatu has a functional free plan with ads. 0xCal requires a subscription after the trial.
• Meal planning and shopping lists — Fitatu includes meal plan features and can generate shopping lists from your planned meals.
• Water tracking — built-in hydration tracking is included in Fitatu.
• Recipe builder — Fitatu's ingredient-by-ingredient recipe builder lets you save custom meals for repeated logging.
