# Calsy

> Calsy is an AI-powered calorie counter and nutrition tracker for iOS. Users snap a photo of any meal and Calsy's AI calculates calories, protein, carbs, fat, and a Health Score (A–E grade) in under 3 seconds. Unlike MyFitnessPal or Lose It, Calsy requires zero manual entry — photo-first food logging combined with a 300,000+ product barcode database. Calsy also flags 100+ harmful food additives (E250 nitrites, E171 titanium dioxide, E951 aspartame) and classifies every meal by processing level.

## What makes Calsy different

Other calorie trackers make users search databases and type every meal manually — which is why most people quit within a week. Calsy is photo-first: take a picture, AI identifies every food item on the plate, and logs calories and macros automatically. Beyond raw calories, Calsy scores each meal 0–100 (grades A through E) based on food quality — protein source, fiber, sugar, additives, and processing level — so users know whether their diet is actually supporting their goals.

## Core features

- **Macro tracking** — automatic protein, carbs, fat, fiber, sugar, sodium breakdown
- **Water tracking** — one-tap hydration logging

- **Progress charts** — nutrition trends over days, weeks, months
- **35+ languages** — full localization including AI food recognition
