The final version of the form will be sent directly to all registered participants before the deadline.

Each team must create a demo video showcasing the final version of their app. This video should be publicly available on YouTube or another video sharing platform, and the link must be included in the submission form.

Your demo video should include:

• A short introduction describing your app and its purpose;
• A guide to the functionality and user interface of your application;
• Explaining your target audience;

Brainstorm and Pi App Studio

Participants can use the Brainstorm app in the Pi browser to share their prototypes, connect with others, and increase visibility in the Pi community.

If you've prototyped your app using Pi App Studio or the developer portal, you can link it directly to your project record on the Brainstorm platform. This will help you showcase your idea, gather early feedback, and discover potential colleagues or collaborators for the hackathon.

Connecting your application to Brainstorm:

1. Open the Brainstorm app from the Pi browser.
2. Click the "Suggest" button on the bottom navigation bar.
3. Fill in the project title and short summary according to the instructions on the page.
4. Once submitted, scroll to the bottom of the project page and click "Link this project to an app on the developer portal."
5. You will be able to choose from apps you have already created in Pi App Studio or the developer portal.

Once your project is linked, it will be visible to other Brainstorm users, allowing more Pioneers to view, follow, and interact with your idea.

Developers, start building!

Pi Hackathon 2025 is an opportunity for developers to make meaningful contributions to the Pi ecosystem by creating real-world applications that promote Pi usability and community engagement. Whether you're an experienced developer or just starting out, this is your chance to build something impressive, collaborate with others, and showcase your ideas to the global Pi community.

Conclusion

The network is ready for the creativity, innovation, and determination that participants will bring to this event!
