Calorie counter from photo
Calorie counter from a photo of your meal
Take a photo of your plate and FoodWarz estimates the calories and macros for what is on it. No database searching — just snap, review the estimate, adjust the portion if needed, and save it to your food diary.

How photo calorie counting works
The AI looks at your photo, identifies the dish and the likely components, then maps them to reference nutrition values and a typical serving size. You see calories plus protein, fat and carbs, and a slider to correct the weight.
- Snap one clear photo of the whole plate in decent light.
- Review the recognised items and the estimated portion.
- Adjust grams or swap an item if the AI missed something.
- Save — it lands in your diary with the day’s running total.
What a photo can and cannot see
A photo cannot measure hidden oil, butter, sugar or the exact weight under the surface, so mixed dishes and restaurant plates are the hardest to estimate. That is normal for every photo calorie tool.
FoodWarz handles this by making the result editable and by asking for portion confirmation, instead of pretending a single photo is exact. For simple, separated foods the estimate is closest; for saucy, layered dishes, confirm the portion.
Foods that photograph well
Clearly separated foods — grilled chicken with rice and vegetables, a piece of fruit, a sandwich — are easiest for the AI. For these, a quick snap gets you a usable number faster than any manual search.
Photo logging vs typing every food
Faster capture
One photo replaces several database searches and portion guesses.
Fewer skipped meals
Because it is quick, you are far more likely to log lunch instead of forgetting it.
You stay in control
Every photo estimate is editable, so you fix what the camera could not see.
Photo calorie counter FAQ
How accurate is counting calories from a photo?
It is a good estimate for simple, separated foods and rougher for saucy or mixed dishes. Confirm the portion before saving for the most reliable diary.
What if the AI gets the food wrong?
You can correct the item, change the portion size or add a missing ingredient in a tap before it saves.
Can I also log by text or voice?
Yes. Photo, text, voice and barcode all work, so you can use whatever is fastest for the moment.
