Choose Fitia if you want personalized meal plans, an AI coach and a shopping list in English or Spanish, on Android or Apple Watch as well as iPhone, and you’re happy to pay for Premium. Choose Calorix if you’re on iPhone and want the basics free: barcode scanning, food search, fasting and a few AI scans a day, with photo estimates you can check ingredient by ingredient, and Toasty, a living pet who eats, drinks and celebrates with you as you log.
We make Calorix, so we’re not neutral. Every fact about Fitia comes from its App Store listing, its website, its terms of service or its Y Combinator profile, checked on October 11, 2026. Prices are US prices and vary by country.
Free versions
The two free versions are very different. Fitia’s own free vs Premium table marks these as Premium-only: barcode scanning, photo, voice and text food logging, creating foods with AI, custom calories and macros, Apple and Google Health sync, intermittent fasting and every meal-planning feature. The free version has a limited verified database, up to 4 meals and ads (Fitia).
Calorix’s free version includes barcode lookups, food search and manual logging with no limit, custom calorie and macro targets, Apple Health, water, weight and every fasting schedule, plus 3 AI scans a day (pricing).
Logging
With Premium, Fitia logs food by photo, voice or “typing (like notes)”, and by barcode. Calorix does the same plus nutrition labels, and returns each photo as a review card listing every ingredient with its portion, grams, calories and a confidence badge that you can correct (AI scanner).
Fitia’s App Store listing calls it “the fastest & most accurate calorie counter”, without a published method. Calorix doesn’t claim to be the most accurate; we explain why photo estimates miss, and what the evidence says, in apps that count calories from a photo.
Meal plans and coaching
This is where Fitia leads. Its Premium plan includes automatic, personalized meal plans, a meal plan builder, personalized recipes, a shopping list and “an AI coach that adapts to your progress”, per its listing. Calorix suggests meals that fit your remaining calories and macros and builds a weekly plan with a grocery list (made by AI with Pro, from the app’s recipes otherwise), but it doesn’t coach.
Motivation
Fitia’s listing mentions a Fitia Teams feature but no mascot or streak system. Calorix has Toasty, a pet ember who reacts when you log, with daily and weekly challenges and streak freezes that are earned, never sold (Toasty).
Platforms and languages
Fitia runs on iPhone (iOS 16 or later), Apple Watch and Android, in English and Spanish. Calorix 2.0 runs on iPhone only (iOS 17 or later), in 16 languages including Spanish for Spain and Latin America; an Apple Watch app is planned.
