DISCOVERCreate a plant-based challenge app
Vegan and vegetarian nutrition app: a 30-day plant-based challenge, one step a day
Every morning, a push opens the day's step: a filmed recipe, what to know, tomorrow's shopping. The first three days are free, the rest is for subscribers.
Your plant-based challenge becomes a native app, built without programming: thirty pieces of content prepared ahead, a push scheduled for each morning, the first days open to all and the rest by subscription.
Free 30-day trial - No credit card required
Thirty days, thirty appointments
At 7:30 a.m., the day's push; one tap, and the step opens
A challenge lives on regularity. Every morning, a scheduled push announces the step: “Day 12: a packed lunch”. Participants open it and find everything in one place: the recipe on video, the explanation, the shopping list for tomorrow. Nothing to look for, nothing to remember: the app comes to them, thirty days in a row.
One step, one complete piece of content
The filmed recipe, the why, the shopping
Each day is an article: a video of the recipe, a few paragraphs on the day's topic (replacing meat in a family dish, pairing legumes and grains, reading a label), then tomorrow's shopping list. Days 1 to 3 stay open to spark interest; from the fourth on, subscribers take over, and everyone else only sees the first lines.
Preparing the challenge once and for all
Four stages, before the first morning.
Write
The thirty steps, with their videos, in a Challenge section.Lock
Days 4 to 30 for subscribers; the first three stay open.Schedule
Each step's publication date, and thirty pushes at 7:30 a.m.Announce
An open article and a push give the start date, two weeks ahead.
A group challenge, on a fixed date
Everyone starts on the same day and moves at the same pace
Pushes go out on the dates you set, so the challenge starts on the same day for everyone, the 1st of the month for instance, and each participant gets the day's step at the same time as the others. Someone who arrives on day ten finds the earlier steps in the section and catches up at their own pace. Run a new edition whenever you like, on another theme: breakfast, batch cooking, festive meals.
AI working for the challenge
Three uses, and their price.
To answer
An assistant for the day's questions
“What goes into a meat-free lunchbox?” The Chatbot searches your published steps, replies in the participant's language and links to the step it used. Anyone without a subscription only gets answers drawn from the three open days.
$35/month
To extend
The thirty-day calendar
Describe a grid of thirty squares, each opening its step: the AI Extension Builder generates it, styled with your branding, as a new part of the app.
Free
To operate
Thirty pushes scheduled in one request
Through the MCP server, Claude or ChatGPT prepares the thirty notifications, one per morning, from your step titles; you check the list before it schedules them on the app.
Included
Nutrition, without promises
Protein, iron, vitamin B12: inform, and refer to a professional
Nutrition questions come up quickly once meat is off the plate. Your steps answer them with general, sourced information, without announcing any effect on health. A page read on day one says it plainly: during pregnancy, for a child or with a chronic illness, a change of diet is prepared with a doctor or a dietitian.
The vegan blogger
Her January challenge becomes an app: the first three days bring readers in, the subscription opens the rest and past editions.
The plant-based eating association
It runs a free challenge, with nothing locked, and keeps the morning push to support its participants.
The vegetarian recipe blog
When the project is a recipe collection sorted by season rather than a challenge, another page covers it.

A subscriber can also follow the challenge on a computer.
The budget of a plant-based challenge app
Subscriptions are sold in the store apps, from Premium, with the Memberships extension; the Pro plan includes it. Video, scheduled pushes and hosting add nothing.
| Premium · store apps, web version | $55 /month, billed yearly |
| Memberships, for Premium | $49 /month |
| Pro · Memberships built in | $105 /month, billed yearly |
Apple and Google keep a share of each subscription, GoodBarber none. Each store bills its developer account.
Extension Store
The extensions of a challenge: Memberships (with Premium or within Pro), articles and video, scheduled and automatic push, then three AI tools: Chatbot, AI Extension Builder, MCP server.

Plant-based challenge app: your questions
Can everyone start the challenge on the day they choose?
Not with scheduled pushes: they go out on the dates you set, so the challenge is a group one. A participant who joins late finds every step already published in the section and moves at their own pace, without the notifications of the days they missed.
Can I sell the challenge on its own, without a subscription?
No: in-app purchase takes the form of a subscription here, monthly or yearly. One month covers the challenge; participants then stop their subscription from their Apple or Google account, if they wish.
Can vegetarians and vegans follow the same challenge?
Yes. Each step gives the vegetarian version and its vegan variant, and a single subscription opens everything: access is the same for every subscriber.
Is the challenge suitable for everyone?
It gives general information, and says so. A pregnant woman, the parents of a child, someone on medication or living with a chronic illness first talk to a doctor or a dietitian. The app asks nothing about participants' health.
What do the stores keep on each subscription?
Most of the time, Apple or Google keeps 15%. In the first year of a subscription, Apple takes 30%, unless your business qualifies for its reduced rate for small companies. GoodBarber earns nothing on these sales.
Which GoodBarber plan for a plant-based challenge app?
Premium and the Memberships extension, or Pro, which builds it in from the start. Selling also calls for the web version, switched on and attached to your own domain.
Your 30-day plant-based challenge becomes a subscription app with GoodBarber, which takes no commission
One step a day, a push every morning, the first days open, recipes on video, an assistant for questions, successive editions.
