Free calorie scanner app: the honest version

Why some features can be free and others cannot

The economics here are simple enough to explain in a paragraph, and knowing them tells you what any app can sustainably give away.

Barcode scanning costs essentially nothing per scan. The decoding happens on your own phone using your own processor. The lookup is a database query measured in fractions of a penny. An app can offer unlimited barcode scanning forever without it appearing on a spreadsheet anywhere.

AI photo scanning costs real money per image. Every photograph goes to a vision model that charges per request. Unlimited free photo scanning is not a generous business decision; it is not a business at all.

That divide explains what you should expect. Any app charging for barcode scanning is charging for something with no marginal cost — a pricing decision, not a technical necessity. Any app offering unlimited free AI scanning is funding it some other way, which usually means advertising or your data.

Here, the free tier is one scan. That is a trial rather than a tier, and we would rather call it that than advertise a "free app" that turns out to mean a seven-day countdown. After it, unlimited scanning is $19.99 a month or $59.99 a year. Everything written on this site — every guide, comparison and reference table — stays free to read without an account.

The four kinds of "free"

Free trial

Full access for 7 to 30 days, card required, converts automatically. Legitimate, but it is not a free app — it is a paid app with a delay. The tell is a card requested at signup.

Freemium with the useful bit removed

The most common pattern in calorie tracking. Scanning works, but macros are behind the paywall, or the diary holds a week, or export is premium. Genuinely free, often not useful. MyFitnessPal's 2022 decision to move barcode scanning itself behind the paywall is the best-known example — see the MyFitnessPal barcode scanner page for what changed.

Free with advertising

You pay in attention and, usually, in data. Worth checking what the privacy policy permits before assuming the price is zero: a food diary is a detailed behavioural record, and it has a market value that is not zero.

Genuinely free, funded some other way

FatSecret is the clearest example: scanning and macros cost nothing because advertising pays for them. That is a real option and an honest one, provided you are comfortable being the audience being sold. What does not exist is a calorie scanner with no adverts, no subscription and no data business — somebody is paying for those database calls.

How to check before you commit

• Is a card required to start? The single best signal. No card means no surprise charge.
• Are macros visible on the free tier? Calories alone tell you half the story. If protein, carbs and fat are premium, the useful part is the paid part.
• How far back does the free diary go? A seven-day history is not a history. Patterns are the entire point of tracking.
• Can you export? If not, your data is a retention mechanism rather than an asset.
• What happens when you stop paying? Some apps lock your existing history behind the paywall retroactively.

What you get here, free and paid

Note what is not in that table: a reduced free scan. There is no second paywall inside a scan here. The free one returns the same panel, the same macros and the same portion controls a subscriber gets — the limit is how many, not how much.

No card is requested for the free scan. The pricing page has the full breakdown.

What a subscription actually costs

$19.99 a month, or $59.99 a year — which is $5.00 a month, and a 75% saving for committing to twelve months.

For comparison, MyFitnessPal Premium is around $20 a month and Lifesum around $9. Billed monthly we sit in the same bracket as MyFitnessPal; the gap only opens on the yearly plan, where $5.00 a month undercuts both. That is not generosity — it is that we do one thing and have no app store cut, content team or advertising stack to fund. If all you want is the lowest possible monthly bill, Lifesum is cheaper than we are, and we would rather say so than pretend otherwise.

Take your free scan. Nothing to install, and no card unless you subscribe.
