How to Use AI Coding Tools to Build Your First App in 3 Days

If you’re like most indie hackers or side project builders, the thought of developing your first app can feel daunting. You might think you need to be a coding wizard or spend months learning programming languages. But here’s the good news: with the rise of AI coding tools, you can build your first app in just three days. Seriously.

In this guide, I’ll walk you through the essential AI coding tools, how to use them, and what you can realistically achieve in a short timeframe. Let’s dive in!

Day 1: Planning Your App

Define Your App Idea

Before you start coding, you need a clear idea of what your app does. Spend a couple of hours brainstorming and sketching out your concept. Keep it simple for your first project.

Prerequisites

• A computer with internet access
• Basic understanding of what apps do (but no coding needed)
• A willingness to learn and experiment

Day 2: Choosing Your AI Coding Tools

Top AI Coding Tools for Beginners

Here's a list of AI coding tools that can help you on your journey. They vary in features, pricing, and capabilities, so choose wisely based on your app idea.

| Tool Name | What It Does | Pricing | Best For | Limitations | Our Take | |--------------------|-----------------------------------------------------|-----------------------------|----------------------------------|--------------------------------------|-----------------------------------| | GitHub Copilot | AI-powered code suggestions directly in your IDE | $10/mo | Solo developers | Not a full replacement for knowledge | We use it for quick suggestions. | | Replit | Online collaborative coding environment | Free tier + $7/mo Pro | Rapid prototyping | Limited features in free tier | Great for quick testing. | | ChatGPT | Generates or explains code snippets | Free, $20/mo for Plus | Learning and debugging | May generate incorrect code | Use it for understanding concepts.| | Codeium | AI code completion tool with multi-language support | Free | Multi-language projects | Less mature than others | We find it helpful but limited. | | Tabnine | AI-powered code completion for various IDEs | Free tier + $12/mo Pro | Developers wanting speed | Can be hit or miss | We don’t use it due to cost. | | Ponic | AI tool for building web apps without coding | Free, $29/mo for Pro | No-code app builders | Limited customization options | We tried it, but found it basic. | | Anvil | Build web apps with Python without much coding | Free tier + $25/mo Pro | Python developers | Not as flexible as JavaScript | Use it for Python projects. | | Bubble | No-code web app builder with visual interface | Free tier + $29/mo Pro | Non-coders | Can be overwhelming for new users | We avoid it for complexity. | | FlutterFlow | Drag-and-drop interface for Flutter apps | Free tier + $30/mo Pro | Mobile app builders | Limited support for custom code | We like it for mobile prototypes. | | AppGyver | No-code platform for building apps | Free | Beginners | Limited functionality for complex apps| We use it for quick prototypes. | | Vercel | Hosting platform optimized for frontend frameworks | Free tier + $20/mo Pro | Frontend developers | Less backend support | We use it for hosting. |

Our Recommendation

For absolute beginners, I recommend starting with Replit for prototyping and GitHub Copilot for coding assistance. They have a user-friendly interface and provide quick feedback.

Day 3: Building and Launching Your App

Step-by-Step Workflow

1. Set Up Your Environment:

   • Open Replit and create a new project.
   • Use GitHub Copilot to help you write the initial code skeleton based on your app idea.

2. Develop Core Features:

   • Focus on the main functionalities. Use ChatGPT to generate snippets for specific features.
   • Test as you go. Replit allows you to run your code instantly.

3. Iterate and Improve:

   • Use feedback from friends or potential users to refine your app.
   • Incorporate any suggestions or bug fixes.

4. Deploy Your App:

   • Once you’re satisfied, use Vercel to deploy your app. Follow their simple setup guide.

What Could Go Wrong

• Technical Errors: If your app doesn’t work, double-check your code, and use ChatGPT for debugging help.
• Overcomplicating Features: Stick to your initial plan. Adding too many features can lead to confusion.

What’s Next?

Once your app is live, start gathering user feedback. Use tools like Hotjar for user analytics and Mailchimp for email outreach to keep your users engaged.

Conclusion: Start Here

Building your first app in three days is entirely possible with the right tools. Start with a simple idea, use AI coding tools like Replit and GitHub Copilot, and don’t shy away from seeking help when you hit roadblocks.

By following this guide, you’ll not only launch your app but also gain valuable skills along the way. So, pick your tools, set aside some focused time, and start building!
