How to Build Your First App Using AI Tools in 3 Days

Building your first app can feel like a daunting task, especially if you're a beginner. The good news is that with the right AI coding tools, you can create a functional app in just three days. In this guide, I'll walk you through the process, share specific tools, and highlight what actually works based on our hands-on experience.

Day 1: Planning Your App

Define Your App Idea

Before diving into development, take some time to outline your app's purpose and features. Ask yourself:

• What problem does my app solve?
• Who is my target audience?
• What are the must-have features versus nice-to-haves?

Create a Wireframe

Use a tool like Figma or Sketch to create a simple wireframe of your app. This doesn't need to be perfect, but it should give you a visual layout of the user interface.

Tools for Wireframing:

• Figma: Collaborative design tool with a free tier for individual use.
• Sketch: Great for Mac users, starts at $99/year.

Our Take

We use Figma for our wireframing because of its collaborative features. Sketch is powerful but limited to Mac users.

Day 2: Development with AI Tools

Choose Your AI Coding Tools

You’ll need the right tools to actually build your app. Here’s a list of AI coding tools that can speed up your development process.

| Tool Name | Pricing | Best For | Limitations | Our Take | |------------------|-----------------------------|------------------------------|--------------------------------|-----------------------------------| | Bubble | Free tier + $29/mo pro | No-code web apps | Limited mobile capabilities | Great for MVPs; easy to use. | | AppGyver | Free | No-code app development | Learning curve for complex apps| Good for simple apps. | | Adalo | Free tier + $50/mo pro | Mobile app creation | Performance issues on bigger apps| We prefer Bubble for web apps. | | OutSystems | $0-1,500/mo (depending on user count) | Enterprise apps | Expensive for small projects | Too pricey for indie hackers. | | ChatGPT | Free + $20/mo for pro | Code generation | Not perfect; needs tweaking | Use for boilerplate code. | | Glitch | Free | Collaborative coding | Limited to small projects | Great for quick prototypes. | | Replit | Free + $20/mo for teams | Collaborative coding | Limited language support | We use it for quick scripts. | | Appy Pie | Free tier + $18/mo pro | Simple app creation | Basic features | Not for complex apps. | | Thunkable | Free tier + $50/mo pro | Cross-platform mobile apps | Limited customization | Good for rapid prototyping. | | Codex by OpenAI | $0.03 per token | Code generation | Requires programming knowledge | Use for specific coding tasks. |

Our Recommendation

For most indie hackers, Bubble is the best choice for web apps, while Adalo works well for mobile.

Day 3: Testing and Launching

Testing Your App

Once your app is built, it’s crucial to test it. Use tools like UserTesting or Maze to gather feedback from real users.

Launching Your App

Deploy your app using services like Vercel or Netlify. Both offer free tiers that are perfect for indie projects.

Troubleshooting Common Issues

• App not loading: Check your API keys and network settings.
• UI issues: Review your wireframe against your app for discrepancies.
• User feedback: Iterate based on feedback from your testers.

What's Next?

After launching, focus on marketing your app. Utilize social media, join relevant communities, and consider using low-cost tools like Mailchimp for email marketing.

Conclusion: Start Here

Building your first app in three days is entirely feasible with the right AI tools and a solid plan. Start by defining your app idea and wireframing it, move on to development with tools like Bubble and Adalo, and finally, test and launch your app effectively.
