Building Your First App

Step-by-step guide using AI app builders.

Step 1: Define Your Application

Good Prompt Template:

Build a [type of app] that allows users to [main action].
Key features:
- [Feature 1]
- [Feature 2]
- [Feature 3]

User flow:
1. User [first action]
2. User [second action]
3. System [response]

Design style: [modern/minimal/colorful/professional]

Example:

Build a task management app that allows users to organize
their daily work.

Key features:
- Create, edit, delete tasks
- Organize tasks into projects
- Set due dates and priorities
- Mark tasks complete

User flow:
1. User logs in
2. User sees their tasks organized by project
3. User can add new tasks or modify existing ones

Design style: Clean, minimal, uses soft colors

Step 2: Iterate on Generated Output

First Generation:

• Review the initial output
• Identify what's working
• Note what needs changes

Refinement Prompts:

"Make the task cards larger and add a subtle shadow"
"Add a sidebar for project navigation"
"Include a search bar at the top"
"Change the color scheme to blue and white"

Step 3: Add Functionality

Incremental Feature Addition:

"Add user authentication with email/password"
"Create a settings page for user preferences"
"Add the ability to share projects with other users"
"Include email notifications for due dates"

Step 4: Polish and Deploy

Finishing Touches:

"Improve the loading states with skeleton screens"
"Add helpful error messages for form validation"
"Optimize for mobile devices"
"Add a favicon and improve the page title"
