Snap once, done — no follow-up taps
Some photo calorie counters return a guess and then ask you to confirm 4 things. Calzy returns a confidence-rated result and lets you adjust only if you want to.
A photo calorie counter is the natural next step for food tracking. Manual entry is the reason most people quit logging within a week — typing 4 ingredients, picking the right database entry, and guessing portion sizes turns a 30-second action into a chore. Calzy fixes that by letting the camera do the work. Open the app, point at the plate, tap once, and within 3 seconds you have calories, protein, carbs, fat, fiber, sugar, sodium, and a 0–100 Health Score. Then keep eating.
What makes Calzy different
Multi-item plate detection
Calzy segments the plate. A picture with chicken, rice, and broccoli is logged as three items with three accurate portions — not as one ambiguous "meal".
Global cuisine, not just US food
The AI is trained on dishes from Europe, Asia, Latin America, the Middle East, and Africa. Sushi, banh mi, dolma, mole, jollof rice, pierogi — all recognized natively.
Health Score grades the meal
Beyond calories, every meal gets a 0–100 quality score and an A–E letter grade based on protein source, fiber, sugar, additives, and processing level.
Barcode scanner included
For packaged foods, snacks, and supplements, the built-in barcode scanner gives instant access to a 300,000+ product database with exact nutrition data.
Apple HealthKit sync
Calorie, protein, water, and step data sync with Apple Health, so your daily nutrition is consistent with the rest of your iOS health stack.

FAQ
How does a photo calorie counter work?
A photo calorie counter uses computer vision to identify food in an image. The AI segments the plate, recognizes each food item, estimates the portion size, and looks up the nutrition data per item. Calzy adds a Health Score on top so you also see whether the meal is high quality or ultra-processed.
Is photo calorie counting accurate?
Modern photo calorie counters are accurate enough for daily tracking and are usually more accurate than manual portion guessing. Calzy returns a confidence rating with each result and lets you adjust portions if you want a tighter number. For exact data, the barcode scanner gives packaged-food nutrition straight from the manufacturer.
Do I need a special camera or setup?
No. Calzy works with any iPhone or iPad camera (iOS 16+). No reference object, no measuring spoon, no special lighting required. Just point and shoot.
Can I take photos of restaurant food and packaged snacks?
Yes — the AI handles restaurant plates and home-cooked food. For packaged snacks, supplements, and grocery products, the built-in barcode scanner gives exact nutrition data instantly.
