POINT. SHOOT.
KNOW YOUR CALORIES.

The free AI calorie calculator that works from a photo

CalorieTracker.today is an online calorie calculator and AI calorie tracker in one. Instead of searching a database, just photograph your plate: the app estimates calories, detects ingredients, and breaks down protein, carbs, and fat. Use it as a fast calorie counter for any meal, or alongside a calorie deficit calculator to stay on track. No sign-up, no app to install.

Here is the idea in one line: point your phone at the plate, shoot a single photo, and know your calories in seconds. There is no barcode to find and no database to search. The AI reads the image, identifies the foods it can see, works out a likely portion size, and returns a calorie estimate together with a protein, carb, and fat breakdown. Because it reasons from the picture rather than a lookup table, it copes with home cooking, mixed plates, and restaurant meals that rarely have a tidy label.

Every estimate is an honest range, not a false-precision number. The app grounds its figures in published reference data such as the USDA FoodData Central nutrient database, then adjusts for the portion it sees on your plate. Two similar meals can differ by a hundred calories depending on oil, sauce, and serving size, so we show a sensible span instead of pretending to weigh your food to the gram. For the bigger picture — how calories, macros, and overall eating patterns fit together — the U.S. Dietary Guidelines for Americans are a solid, non-commercial reference. CalorieTracker gives AI estimates, not medical advice.

Why a photo beats a food database

A traditional calorie counter makes you stop, name the food, guess the brand, and pick a serving size from a long list — friction that quietly kills the habit within a week. A photo removes all of that. Snap the plate and the work is done, which is exactly why people who log meals from a photo tend to keep logging. It is genuinely useful for weight loss and running a calorie deficit, for hitting a daily macro target, and for eating out, where a home-cooked database entry never matches what actually arrives at the table.

Frequently asked questions

Is this calorie calculator free?

Yes. You get free photo analyses with no account. Just snap a meal and get an instant calorie estimate.

How accurate is the AI calorie tracker?

It gives an honest calorie range based on what it sees, using USDA reference values. Ranges are estimates, not exact figures.

Can I use it as a calorie deficit calculator?

Yes. Track each meal, then subtract from your daily target to manage a calorie deficit for weight loss.

Which foods does the photo calorie counter support?

It recognises everyday cooked meals, packaged snacks, fruit, drinks, and restaurant plates. Clear, well-lit photos of a single plate work best; very mixed buffets or foods hidden inside sauces are harder to estimate.

How are portion sizes estimated from a photo?

The AI judges portion size from visual cues in the image — plate size, food height, and the space each item fills — then maps it to USDA reference values. It is an educated estimate, so treat the number as a sensible range rather than an exact weight.

Does the calorie tracker work offline?

No. Reading a photo runs in the cloud, so you need an internet connection. There is nothing to install — it runs in your browser on any phone or laptop.

Does it store my food photos?

If you are not signed in, your photo is analysed and not kept. When you have an account, your scans are saved to your history so you can review past meals.

Can it track macros as well as calories?

Yes. Every scan breaks the meal down into protein, carbohydrates, and fat alongside the calorie estimate, so you can follow a macro target, not just a calorie total.
