3. Start Building Your App

Using the tools above, follow these steps:

• Design your app: Use Figma or Bubble for UI/UX. Create wireframes and mockups.
• Develop the backend: Use Replit or GitHub Copilot to write your code. Let Copilot assist you with code suggestions.
• Integrate features: Use Zapier to connect your app with third-party services, automating tasks as needed.
• Test your app: Share it using Glitch or Replit for quick testing with users.

4. Troubleshooting Common Issues

What Could Go Wrong:

• Code errors: If your app isn't functioning, check the console for error messages. GitHub Copilot can help debug.
• Design issues: If the UI looks off, tweak it in Figma or Bubble.
• Integration failures: Ensure API keys are set correctly in Zapier.

5. What’s Next?

Once your app is built, focus on:

• User Feedback: Gather insights from early users to refine your app.
• Marketing: Use platforms like Twitter or Indie Hackers to promote your app.
• Scaling: As your user base grows, you might need to switch to more robust tools like OutSystems.

Conclusion: Start Here

Ready to build your app in 2 hours? Start by defining your app idea and gathering your accounts for the tools listed. The right combination of AI coding tools can drastically reduce your development time and help you get to market faster.

What We Actually Use

In our experience, we rely heavily on GitHub Copilot for code generation, Bubble for no-code app development, and Figma for design. This combination allows us to iterate quickly while keeping costs manageable.
