Cal AI
Cal AI uses photos, barcodes, and meal descriptions to estimate calories and nutrients, then tracks food, exercise, water, and progress.

Cal AI is a mobile calorie and nutrition tracker. Users can photograph meals, scan barcodes, describe food, search a food database, and record calories, protein, carbohydrates, fat, water, exercise, weight, and measurements.
It is aimed at people monitoring nutrition, weight, fitness, or dietary goals. The app supports Apple Health and Google Fit connections and offers a 3-day free trial, but the official pricing page could not be read, so subscription prices are unconfirmed. It does not currently support direct MyFitnessPal history imports.
