DISCOVERCreate a supplement and vitamin app
Supplement and vitamin app: an information media with premium guides and zero health claims
Your readers browse your nutrient sheets for free, subscribe to open the full guides, and know your media is not trying to sell them a bottle.
Your dietary supplement media, published as a native app with no code to write: open sheets, guides reserved for subscribers, an assistant fed by your own texts only, and no shop mixed in with the information.
Free 30-day trial - No credit card required
Inform, and promise nothing
Each guide explains a nutrient; none of them credits it with an effect
A serious guide to magnesium or vitamin D answers the reader's questions: what it is, which foods contain it, how to read the composition on a label, and what the rules in their country allow a label to say. It announces no regained energy and no stronger defenses, and it points to a doctor or a pharmacist for any personal advice. That line is what gives the subscription its value: information that depends on no sale.
Sheets open to all, guides for subscribers
You decide, article by article, what stays open
Keep the short sheets open, one per vitamin or mineral, since they bring readers in. Reserve the full guides for subscribers: reading a label, comparing the forms of a mineral, understanding reference intakes. On a reserved guide, the first paragraphs stay readable up to the one you pick, and the PDF that comes with it stays hidden from non-subscribers. Sales open once ten guides or more are locked, and every subscriber sees exactly the same thing.
Information on one side, sales on the other
This app has no cart; a shop is built with the eCommerce app
A reader who pays to be informed expects texts that push no product. Your media's app therefore sells one thing only: access to your guides, through a subscription taken out in the stores. If your company also markets supplements, the shop belongs to another GoodBarber product, the eCommerce app: catalog, cart, payment and orders, in a separate app.
The pharmacist who writes
The sheets answer questions heard at the counter; the detailed guides, reserved for subscribers, remind readers that personal advice is given at the pharmacy.
The sports nutrition media
Creatine, protein, electrolytes: it compares compositions without naming brands, and publishes a guide for its subscribers every month.
The supplement brand
To sell its products, it needs a mobile shop: that is the eCommerce app for dietary supplement sellers.
The supplement seller's appAI working for your guides
Three precise uses, with their price.
To answer
An assistant that cites your guides
“What's the difference between vitamin D2 and D3?” The Chatbot builds its reply from the guides you have published, responds in whatever language the reader used and names the guide it relied on. Without a subscription, readers only get replies based on the open sheets. State in your guides that personal advice comes from a health professional: the assistant relies on your texts.
$35/month
To extend
A unit converter
Micrograms or international units? A vitamin D converter, described in a few words: the AI Extension Builder generates it as an extra section of the app, in your colors.
Free
To operate
The guide of the month, published from your assistant
Ask Claude or ChatGPT, linked to your app by the MCP server, to put the guide and its push online; review the request, and it is carried out.
Included
A guide updated, readers informed
Instant corrections, automatic push, bookmarks
When a study or a rule changes, correct the guide in the CMS: the app shows the new version right away, without going through the stores. Every new guide is announced by an automatic push, opening with a word you set, such as “New guide:”; the monthly selection is scheduled for the same hour in every time zone. Subscribers bookmark their guides to read them again before buying.
In the app, besides the guides
Search
Find a nutrient, a form or a guide across all your content.
Sections by family
Vitamins, minerals, omega-3, sport: an order that follows your table of contents.
The guide as a PDF
A file to download, attached to the guide and reserved like it.
Bookmarks
A subscriber keeps the iron sheet close at hand.
An offer page in your style
Your subscription offer laid out in your typefaces and colors.
A web version
The open sheets can also be read in a browser, where a subscriber finds all your guides.

The budget of a subscription information media
Subscriptions are bought inside the native apps, so you need Premium plus the Memberships extension, or Pro, which includes it. Hosting, sending notifications and correcting content cost nothing extra.
| Premium · both native apps plus the web version | $55 /month, billed yearly |
| Memberships, on top of Premium | $49 /month |
| Pro · Memberships included | $105 /month, billed yearly |
On each subscription, Apple and Google keep their fee and GoodBarber keeps none. Your developer accounts are billed by the stores themselves.
Extension Store
For a supplement media: Memberships (added to Premium, already part of Pro), articles, push and bookmarks, plus this page's AI trio: Chatbot for questions, AI Extension Builder for the converter, MCP server for publishing.
Supplement and vitamin app: your questions
Can my guides say that a supplement acts on health?
The app publishes what you write, under your responsibility. The media described here informs without promising: it presents a nutrient, its food sources, how to read a label and what the rules in your country allow a label to say, then points to a doctor or a pharmacist for personal advice. It does not replace medical advice, and says so on a page of its own.
Can I sell supplements in this app?
No: it sells access to your guides and nothing else, which is all the stores' in-app purchase is for. A catalog, a cart and orders call for GoodBarber's eCommerce app, a separate product.
Do my readers need to create an account?
Not to read the open sheets. Subscribing takes one tap, with the Apple or Google ID already stored on the phone; after that, the guides also open in the web version.
Can I offer a vitamins plan and a sports plan?
No: the app knows only one plan, and every subscriber opens all your guides. What varies is the length (monthly, yearly, or both for the reader to pick), with its own price in each store.
How much of each subscription goes to the media?
The amount paid, minus the store fee, usually 15%. Apple keeps 30% over the first twelve months of each subscription, unless you're enrolled in its program for small businesses. Nothing goes to GoodBarber.
Which plan for a supplement and vitamin app?
Premium extended with Memberships, or Pro, where Memberships is built in. To sell, the web version must also be running, on a domain name of your own.
GoodBarber publishes your supplement media as an app and sells your guides by subscription, with no GoodBarber commission
Open sheets, reserved guides and PDFs, automatic push, an assistant that cites your texts, no shop mixed in with the information.
