People often find Calorix through a page that compares it with another app: what Cal AI costs, whether MyFitnessPal is free, which apps to try instead of MyFitnessPal. Those pages only help if you can trust them, and you have a good reason not to: we make one of the apps. So here is exactly how we write and check them.
Who writes these pages
The comparison, price, alternatives and guide pages on calorix.ai are written by the Calorix team at Invikta Technology Ltd, the company that makes Calorix (registered in the UK under number 15228536, public record). We sign them as a team. When a named expert reviews a page, their name, credentials and the date of the review will appear on it; we don’t invent reviewers, testers or ratings.
Where our facts come from
For every fact about another app, we go to the most direct source available, in this order:
- The app’s App Store listing in the country named on the page: its description, the in-app purchases Apple lists, the developer’s name and the version history. On a Japanese page that means the Japanese App Store, in yen; on a Spanish page, the Spanish store, in euros. We don’t convert US prices into other currencies.
- The company’s own website, pricing page, help center or terms. When a company publishes a price or a rule, we quote it and link to the page.
- Press coverage and published studies. Ownership changes, funding and accuracy research come from named news outlets and peer-reviewed or conference publications we could find ourselves, never from claims we can’t trace.
Numbers that come only from another company’s blog or a third-party guide are labelled “third-party report”, with its date, and never presented as the app’s official price.
The App Store shows at most ten in-app purchase rows for an app, without saying how long each plan lasts, and the list can change between visits while an app tests prices. When that happens we say so, show what we saw and when, and don’t guess plan lengths.
How we date and re-check
Every comparison and price page shows the date its facts were checked, under the title and in the caption of its tables. We re-check those pages at least once a month and whenever we hear that something changed, update the date only when we actually re-checked, and add a line to the change log at the end of the page saying what changed. Facts about Calorix itself (its prices, trial and free features) come from one configuration file that mirrors App Store Connect, so they change on every page at once.
How we compare fairly
- We say that we make Calorix, at the top of every comparison, price and alternatives page, and again near the sources.
- We never rank our own app inside a list of other apps. On “alternatives” pages, Calorix appears in a separate box labelled “Our app”, or not at all.
- Every comparison has a “when the other app is the better choice” section. Each app does something well, and we say what.
- We compare like with like: the same country, the same date and the same kind of plan, and we say when a comparison can’t be exact.
- We don’t claim tests we haven’t done. If a page has a hands-on test, it describes the method and the results; if it doesn’t, it compares official information only. Accuracy figures for Calorix come only from our published benchmark, which describes its method and limits.
- We use other apps’ names only to identify them, with no logos, and we point to their official App Store listing so you don’t land on a look-alike.
These rules follow the UK Advertising Codes on comparisons, the EU directive on comparative advertising and Japan’s rules on undisclosed advertising, which require comparisons to be verifiable, fair and clearly identified.
How we write and translate
We use AI tools to help us draft and translate pages, then check every fact, price and source against the primary source before publishing, in every language. Each language version is written for readers in that language, with local prices and local apps where we have them, rather than translated word for word.
Health information
Calorix and our calculators give nutrition estimates for general wellness, not medical advice. Calculator formulas cite their sources under every result. We don’t publish pages that recommend a calorie deficit to anyone under 18, make medical claims, or present an app as a treatment for a condition.
What we don’t do
- No paid placements and no affiliate links: we earn nothing when you choose another app.
- No fake reviews, invented experts, made-up test results or ratings collected from other sites.
- No hidden changes: when a fact changes, the change log says so.
Corrections
If you think something on one of our pages is wrong or out of date, tell us from the help page, with a link to the source if you have one. We check it against the primary source, correct what’s wrong and note the correction in the page’s change log.
