DISCOVERCreate a popular science app
Popular science app: your articles and videos for subscribers, plus your readers' questions
Physics, living things, climate, space, computing: you explain science, readers send you their questions, and a subscription opens all your features and videos.
For a science outlet, a channel or an outreach association: an iOS and Android app of its own, made without code, with sections by discipline, features and videos reserved for subscribers, a question form, and Chatbot answers drawn from your articles.
Free 30-day trial - No credit card required
“Why is the sea salty?”
Readers' questions become your best stories
A Form section invites readers to send their question, with a photo if they want to show an insect or an odd cloud. Each submission reaches you by email. You pick the best ones and answer them in articles in a “Your questions” section; the automatic push tells readers when it is out, and the person who asked sees their curiosity turned into a story.
One section per discipline
From living things to climate, locked or open features
Sort your articles the way readers look for them: physics, biology, environment, space, health, computing. Each article is open or reserved; on a reserved feature, non-subscribers read the beginning, up to the paragraph you choose. Diagrams, photos and charts sit in the text, where they help understanding.
Videos that explain
Filmed experiments and animations, reserved or free
Upload your videos to a video section of the app: the candle that goes out under a glass, the animation of a dividing cell. Reserve them for subscribers or leave a few free to spark interest. Bandwidth is not billed; the files use your plan's storage.
Article, uploaded video, YouTube video: what each allows
Three formats for explaining science, three behaviors in the app.
| Article | Video uploaded to the app | YouTube section | |
|---|---|---|---|
| Lockable for subscribers | yes, with a readable opening | yes | no, it stays public |
| Read by the Chatbot | yes, text included | no | no |
| Where the content is stored | in your plan's space | in your plan's space, bandwidth free | on YouTube |
AI for science outreach
Three practical uses, with their price.
To answer
A Chatbot that cites your articles
It answers “Do bees sleep?” from your texts, replying in whatever language the reader used and linking the articles behind the answer; non-subscribers only get answers drawn from free articles.
$35/month
To experiment
A falling-objects simulator
Picture a section where you pick a height and a planet to see how long a fall takes: described in a few sentences in the back office, the AI Extension Builder builds it and adds it to the app.
Free
To measure
What works, asked of Claude
Once linked to the app via MCP, your AI assistant looks up your statistics: “which features were read most this month?”. You know what to explore further.
Included
More for curious minds
Search across every feature
One word, “photosynthesis” or “black hole”, and the articles appear.
Bookmarks
Readers keep a feature to finish later.
Guest researchers
Each author signs their articles, with their name at the top.
Scheduled releases
The eclipse article comes out that very morning.
Comments
Readers react below the article.
Pricing for a popular science app
Premium publishes the app in the stores. To sell the subscription, add Memberships to it; the Pro plan already includes it. The form, push and videos come included, within your plan's storage.
| Premium · iOS and Android apps plus web app | $55 /month, billed yearly |
| Memberships, added to Premium | $49 /month |
| Pro · subscriptions included | $105 /month, billed yearly |
Every subscription pays the store's cut: usually 15%, or 30% at Apple during a subscriber's first twelve months unless you joined its small business program. Nothing goes to GoodBarber.
Extension Store
The building blocks of a science outlet: Memberships, articles, videos, the question form, push and three AI tools: the MCP server, the Chatbot and the AI Extension Builder.
Popular science app: what people ask us
Can a video published on YouTube become subscribers-only?
No: a section fed by YouTube stays visible to everyone. To reserve a video, upload it to a video section of the app, then lock it.
We mostly cover biology and the environment: is this app right for us?
Yes. Create one section per theme (biodiversity, oceans, climate, urban ecology) and reserve the in-depth features for subscribers; the form collects your readers' field observations.
How many items do I need before launching the subscription?
Ten reserved items at minimum. Your web app needs to be live on its own domain name, and locked content opens to subscribers after the stores have reviewed the app.
Can a subscriber read on their computer?
Yes. They subscribe from the iPhone or Android app, and the same login then opens the web version in a browser; the web version itself only redirects to the stores for purchase.
Can we give access to a class or a science club?
Yes: in the back office, each account concerned can receive a gifted subscription, for the length you choose.
Which plan is needed?
You need Premium with its Memberships option, or Pro straight away. Standard, confined to the web app, rules out selling subscriptions.
They built their app with GoodBarber
Customer reviews, all sectors combined.
GoodBarber is a powerful app builder.
GoodBarber is a powerful app builder. If you want to build your app using a pre-built template, GoodBarber is ideal for you. At Global Academy, we almost completed the 5th year using their easy-to-use pre-built platforms to build premium Apps for our customers. Also, Goodbarber's customer support is excellent. Highly recommended.
Great support and always very helpful answers.
Great support and always very helpful answers. Nothing is too trivial for the team to answer.
Responsive support and usually quick.
Responsive support and usually quick. Software is by far the best in the market, with tremendous capabilities for configurations.
Your science outlet in an app, funded by its subscribers
Sections by discipline, reserved features and videos, reader questions through a form, a Chatbot on your articles, a simulator built with AI, a push with each release.
