Plateknow Search for a free AI calorie counter and you get apps that are free to download, free for a few days, or free up to a scan cap — very different things behind the same word.
Which AI calorie counter apps are free? What “free” means
| What the listing says | What you get | Where it stops |
|---|---|---|
| Free to download | The app installs at no cost. | Says nothing about whether you can use it. |
| Free trial | Everything, for a few days. | Usually needs payment details up front and renews unless you cancel. |
| Freemium with a scan cap | A fixed number of photo scans per day or month, with no card. | The cap — the only model you can use indefinitely without paying. |
| Free with ads | Full features, with advertising. | Your attention. Ask whether the ads interrupt you, and what the ad network sees. |
Why AI calorie counters cap free scans
A traditional calorie app searches a food table, which costs almost nothing. An AI calorie counter runs a vision model on every scan, and every scan has a running cost — which is why free tiers are capped by scans rather than features.
Is a calorie counter app subscription worth it?
- A scan cap high enough that you stop thinking about it.
- Longer history, and exports in a format you can leave with.
- Better handling of the food you actually eat.
- No advertising and no data sharing, stated in specifics.
- A “premium” badge on a feature that costs nothing to run.
- Correcting a wrong result. Fixing the app’s mistake should never be paid.
- Your own data. Export is not a premium feature.
Calorie counter app with no subscription: what to ask
- How many scans do I get before paying, and is that per day or per month?
- Do I need to enter a card to try it?
- What happens to my logged meals if I stop paying?
- Where are my food photos processed, and how long are they kept?
- Can I export everything, and in what format?
A free AI calorie counter with no account or card
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.
Correcting a wrong result is never a paid feature, and the first photo works before there is any account to create. There is no advertising in Plateknow — no ad network and no advertising SDK.
More estimates and the longer recaps sit outside the allowance, for people who spend it most days, and paying for them opens later. The terms are stated on the App Store listing; there is nothing to buy on this website.

Is there a completely free AI calorie counter?
There are apps with a real free tier — a fixed number of AI scans, no card, indefinitely. Unlimited free AI scanning is rare, because every scan has a running cost, so judge the cap, not the word.
Is there a calorie counter app with no sign-up?
Plateknow: open it and take a photo. The AI estimates are free, with no account and no card.
Is there a free MyFitnessPal alternative?
Plateknow is one if you would rather photograph meals than search a database: its AI estimates are free with no account and no card, and it scans barcodes for packaged food.
