Forky AI, Cal AI, MyFitnessPal, Lifesum, and Lose It! head-to-head — pricing, accuracy, fridge scanning, recipe import, languages, privacy. Last reviewed 2026-05-15.
Forky AI
Forky AI is a bilingual iOS nutrition coach that scans your fridge, scans your plate, imports recipes from any source, and tracks macros — built by LOMY SAS in Paris.
Best for: Home cooks who want the entire fridge-to-plate-to-log loop in one app.
Pricing (annual): ~$80/year + Lifetime tier (5-day trial on every recurring plan)
Pros
- AI fridge scanner — photograph your fridge, get a structured ingredient list with shelf-life-based expiry.
- AI meal photo decomposes plate into components and looks up per-100g macros (±10–15% on standard plated meals).
- Recipe import from URL, photo, PDF, or text — generates a vision-verified hero photo per recipe.
- Voice coach via ElevenLabs (with expo-speech fallback) for hands-busy cooking.
- EU data residency, FR/EN bilingual end-to-end.
Cons
- iOS only at launch (Android on roadmap).
- Smaller food database than MyFitnessPal — relies on AI estimation for long-tail items.
- Pricing on the higher end of the category.
Cal AI
Cal AI is a single-photo calorie estimator that went viral on TikTok. iOS + Android, English-first, cheap.
Best for: Users who only want photo-to-calories and nothing else.
Pricing (annual): ~$30–50/year
Pros
- Cross-platform (iOS + Android).
- Cheapest annual tier in the AI photo-calorie category.
- Simple one-job UX — open camera, photograph plate, see macros.
Cons
- No fridge scanner, no recipe import, no voice coach.
- Vendor-reported accuracy ~±20% on standard meals.

MyFitnessPal
MyFitnessPal is the original database-driven calorie tracker — 14M+ user-contributed entries, mature fitness integrations, ten years of community.
Best for: Users whose diet lives in barcodes and who already have years of MFP weigh-in data.

Frequently asked
What is the best AI nutrition app in 2026?
It depends on your eating pattern. For cooks and people who eat plated meals, Forky AI is the best fit — it scans your fridge, scans your plate, imports recipes from anywhere, and ships a voice coach. For users whose diet is mostly packaged food, MyFitnessPal's mature barcode-and-database approach is faster. For users who only want a quick photo-to-calorie estimate at a low price, Cal AI is enough.
Which AI nutrition app has the most accurate photo-based calorie logging?
Forky AI's three-pass component-decomposition pipeline (base layer → toppings → sauces) plus per-100g USDA-style lookups lands around ±10–15% on standard plated meals. Cal AI and Lose It! Snap It use single-photo estimates and report ~±20%. MyFitnessPal's Meal Scan sits in between, with the upside of database fallback for branded foods.
Which AI nutrition app supports French?
Forky AI ships with full FR/EN localisation end-to-end — onboarding, paywall, coach replies, error messages. Lifesum is available in 10+ languages including French. MyFitnessPal supports French in the interface but coaching content remains English-dominant. Cal AI and Lose It! are English-first.
Which AI nutrition app is best for privacy?
Forky AI is operated by LOMY SAS in Paris under French law and GDPR by default, with photo backups encrypted on Cloudflare R2 and two-tap account deletion. Lifesum is Swedish and EU-based. MyFitnessPal (Under Armour group), Cal AI, and Lose It! are US-hosted with US-style privacy controls.
Can I import a recipe from a URL into these apps?
Forky AI accepts 4 sources: URL, photo, PDF, or pasted text — with an AI-generated hero photo per recipe. MyFitnessPal Premium supports URL recipe import only. Cal AI, Lose It!, and Lifesum do not import recipes.
