Plateknow Every calorie app here reads a photo and scans a barcode. The difference is what happens next: whether you can see how it got the number, how many taps a fix takes, and whether it wants an account first.

Why Plateknow is the best photo calorie app for real meals
- Calories from a photo, and you see how. The plate is split into dishes on screen before a number appears.
- Wrong? One tap. The fix is on the result card — no re-shoot, no food search.
- Portions in fractions. Two thirds of a bowl, half a sandwich, logged as eaten.
- Barcode scanner for packaged food. It reads the barcode and the nutrition panel together, and knows a packet the next time.
- A food diary without the counting. No goal, no deficit; every number can be switched off.
- It asks how the meal left you. Energy, focus, digestion, fullness — kept beside that meal.
- The free version comes with an allowance: ten AI estimates a day, and no account at all — the app does not sign you in to anything. The allowance sits on the estimate, never on the diary: log every meal you eat, type in what it was once the allowance is spent, and the check-ins still come. Paying is for people who run past it — it raises the estimate allowance and opens the longer recaps.
How to choose a calorie counting app
If most of what you eat is homemade or from a restaurant, pick a photo-first app that is quick to correct. Scan what comes in a packet, photograph the rest — Plateknow does both.
That is the target. The hard part is the other half — knowing what you actually ate.
Download freeIs there a free AI calorie counter with no account?
Yes. Plateknow’s AI estimates are free, with no account and no card — open it and take a photo.
Are photo calorie apps accurate?
On a plate you can see clearly, they get the size of the meal about right; oil, sauces and whatever is hidden underneath are what they miss. That is why Plateknow shows how it read the plate first, and fixes in one tap.
Is there a free calorie app with a barcode scanner?
Plateknow scans barcodes along with the nutrition panel, so the numbers are the ones printed on the packet, and it recognises a product the next time you scan it.
What is the best calorie counter app for homemade food?
A photo-first one. Homemade food has no barcode and rarely matches a database entry, so what matters is reading the plate, portions in fractions, and a fast fix.
Cal AI vs MyFitnessPal — which is better?
Both read photos and scan barcodes. If you also want free AI estimates without an account, to see how the plate was read, and to fix it in one tap, the table above shows where Plateknow differs.
