I asked developers for a quote and got a number I could not justify.
You would have to pay for months of work before you know if anyone wants the app. So the idea stays on hold.

Vibe Coding Bootcamp
A one-week course on building mobile apps with Claude Code
In five full days you learn how app development works and build your own app for iPhone and Android with Claude Code. You describe what you want in plain English, Claude Code writes the code, and an instructor guides you through every step.
Who usually comes to us
You have an idea for an app, but no clear way to build it.
Most people we talk to are in one of these situations.
I tried an AI app builder. It looked great until it broke.
Every fix breaks something else. You do not understand the code it wrote, so the project stalls.
Every small change depends on a developer.
You wait in their queue and cannot tell if the work is good or how long it should take.
I use AI every day, but I have never built a product with it.
You want to understand how people use the same tools to build working software.
✓See your week
Build the app yourself, with Claude Code and an instructor.
You keep the code and understand how each part works.
Your week, Monday to Friday
Every evening you go home with more of your app working on your phone.
Your app opens on your phone
Learn how app development works, set up Claude Code and turn your idea into a one-page plan.
First screen on your phoneAll the screens work together
Build the main screens and the flow between them, one clear task for Claude Code at a time.
An app you can click throughData, login and AI
Add a database, sign-up and login, and one AI feature that makes your app useful.
An app that knows its usersTesting
Create automated tests with Claude Code, try each other's apps and fix what the group finds.
A more stable versionPublishing and demo day
Learn how the App Store and Google Play work, prepare your app and present it to the group.
Demo to the groupOn Friday evening
What you take home
A working app of your own and a clear understanding of how to build the next one.
- Your own app for iPhone and AndroidBuilt from one codebase with Claude Code and Expo.
- The full code, in your own GitHubIt belongs to you. Change it, extend it or hand it to a developer later.
- An understanding of publishingYou know what the App Store and Google Play ask for, so you can decide if and when to publish.
- A method you can repeatPlan, build step by step and test, the way product teams work.
Why learn this now
Building software with AI has become a practical skill.
Claude Code can write most of the code for an app. What it needs from you is a clear plan, precise tasks and someone who checks the result. This course teaches that part.

“Most people do not fail at building an app because it is hard. They fail because nobody shows them the order in which to do things.”The idea behind this bootcamp

We have taught people to build software since 2015
We teach live, in small groups, with an instructor. This bootcamp applies that approach to building software with AI.

Questions
Before you decide
Do I need to know how to code to learn vibe coding?
No. You describe what you need in plain English, Claude Code writes the code, and the instructor explains what is happening and how to check it. You should be a confident computer user who already uses ChatGPT or Claude.
Is this a Claude Code course or a vibe coding course?
Both. Vibe coding is the way of working: you describe the product and AI writes the code. Claude Code is the main tool you learn to use for it, on your own project.
What if I do not have an app idea yet?
We help you choose one on the first morning. Good first apps solve one clear problem: a booking tool, a habit tracker, a client portal or an internal tool for your team.
I use Windows. Can I join?
Yes. You run your app on your own phone through Expo, so you do not need a Mac. You need a laptop and a smartphone.
How is this different from an AI app builder?
An app builder gives you a template that lives inside its platform. Here you get real code that belongs to you, and you learn how to keep improving it.
Can I take the bootcamp online?
Yes. Online students join the same live class as students in Barcelona and get the same help from the instructor.
What does it cost beyond the tuition?
A Claude subscription that includes Claude Code, paid directly to Anthropic. Expo, Supabase and GitHub have free plans that are enough for the course.
Do I need Apple and Google developer accounts?
Not to take the course. During the week you run your app on your own phone. You only need developer accounts if you decide to publish, and the stores decide whether to approve an app.
