How to Iterate

One of the best things about Constructr is that your apps aren’t set in stone. You can iterate, refine, and improve them at any time. Here’s how to make the most of iteration.

​
The Iteration Process

After your app is built, you can request changes by simply describing what you want to modify. The AI agents will update your app while keeping it running.

​
Step 1: Identify What to Change

Think about what could be improved:
  • New features you want to add
  • UI/UX improvements for better user experience
  • Bug fixes or issues you’ve noticed
  • Performance optimizations
  • Integration additions or modifications

​
Step 2: Describe Your Changes

Just like when you first built your app, describe what you want to change in plain language. Be specific about:
  • What needs to change
  • Where it should change (which page, feature, etc.)
  • Why you want the change (if helpful context)
  • How it should work (if you have a specific vision)

​
Step 3: Review and Deploy

The AI agents will:
  1. Analyze your requested changes
  2. Update the relevant parts of your app
  3. Test the changes
  4. Deploy the updates
Your app stays live during updates, so users aren’t interrupted.

​
Iteration Best Practices

Begin with minor improvements to get comfortable with the iteration process. Small, focused changes are easier to review and validate.
The more specific you are about what to change, the better the results. Instead of “make it better,” say “increase the button size and change the color to blue.”
Make changes in logical increments. Don’t try to change everything at once—it’s easier to review and test smaller updates.
Always test your app after iterations to ensure everything works as expected. The QA agent helps, but your validation is important too.
Consider keeping track of what you’ve changed and why. This helps you understand your app’s evolution and makes future iterations easier.

​
Common Iteration Scenarios

​
Adding New Features

Example:
“Add a search bar to the task list page that allows users to search tasks by title or description. The search should filter results in real-time as the user types.”

​
Improving UI/UX

Example:
“Make the dashboard more visual by adding charts for task completion rates. Use a bar chart for daily completion and a pie chart for task status distribution.”

​
Fixing Issues

Example:
“The date picker isn’t working on mobile devices. Please fix it to work properly on all screen sizes and ensure the calendar popup is touch-friendly.”

​
Adding Integrations

Example:
“Add Slack integration so that when a task is marked as complete, it sends a notification to the #tasks channel with the task title and who completed it.”

​
Performance Improvements

Example:
“The task list is loading slowly when there are many tasks. Please add pagination to show 20 tasks per page with a ‘Load More’ button.”

​
Iteration Workflow

1

Use Your App

Use your app in real scenarios to identify areas for improvement.
2

Gather Feedback

Collect feedback from users about what works and what doesn’t.
3

Prioritize Changes

Decide which changes will have the biggest impact.
4

Request Updates

Describe your changes clearly and submit them for iteration.
5

Review & Test

Review the changes and test them thoroughly.
6

Deploy

Deploy the updated version when you’re satisfied.

​
Tips for Effective Iteration

  • Be patient: Complex changes may take a bit longer
  • Communicate clearly: The better you describe what you want, the better the results
  • Test thoroughly: Always test changes before deploying to production
  • Document changes: Keep notes on what you’ve changed for future reference
  • Iterate regularly: Regular small improvements are better than occasional large overhauls

​
When to Start Fresh

Sometimes, it’s better to start fresh rather than iterate extensively:
  • When the core concept has changed significantly
  • When the app structure needs a major overhaul
  • When you want to try a completely different approach
Don’t hesitate to build a new version if that makes more sense for your needs.
