Iterate & Improve

Gather feedback

The most valuable insights come from watching people use your app. Here is how to collect feedback:

Talk to users

Ask people to try your app while you watch. Note where they get confused or stuck. Ask open-ended questions:

• "What were you trying to do?"
• "What did you expect to happen?"
• "What would make this easier?"

Add analytics

Tools like Vercel Analytics or PostHog show you how people actually use your app. Which pages do they visit? Where do they drop off?

Collect feedback in-app

Add a simple feedback form. Even a "Was this helpful?" with thumbs up/down gives valuable data.

Prioritize improvements

You will get more feature requests than you can build. Use this framework to decide what to work on:

Impact vs Effort

For each potential feature, ask:

• Impact: How much will this help users?
• Effort: How long will this take to build?

Start with high-impact, low-effort items. Save big projects for later.

Add features with AI

Use the same workflow from Step 5 for new features:

1. Define what you want clearly
2. Ask AI to build it
3. Test thoroughly
4. Deploy

Users have requested the ability to set reminders for tasks.

I want to add:
- A "remind me" button on each task
- Date/time picker for when to remind
- Email notification at the scheduled time

Here is my current Task component:
[paste code]

Start with the UI, then we will add the notification logic.

Refactoring with AI

As your codebase grows, it may get messy. AI can help clean it up:

• Extract components: "This file is too long. Extract the form into a separate component."
• Add types: "Add TypeScript types to these functions."
• Improve performance: "This component re-renders too often. Add useMemo/useCallback where appropriate."
• Update dependencies: "Update all packages to their latest versions and fix any breaking changes."

When to scale

Do not optimize prematurely. Scale when you actually need to:

• Database slow? Add indexes, optimize queries
• Too much traffic? Upgrade your hosting plan
• Costs too high? Look for inefficiencies

AI can help diagnose and fix performance issues. Just describe the symptoms and share relevant metrics.

Keep learning

Vibe coding evolves fast. New tools and techniques appear constantly. Stay current by:

• Following AI tool announcements
• Joining communities (Discord, Twitter/X, Reddit)
• Building more projects

The best way to get better is to keep shipping.
