Building an App with ChatGPT: How I Finished It So Fast

Building an App with ChatGPT: How I Finished It So Fast

When I started working on my app idea, I wasn’t sure how much time it would take — especially since I only had a couple of hours per day.
But to my surprise, I managed to complete and launch my MVP in just a few weeks. The key? Building an app with ChatGPT.

Treating ChatGPT like a co-pilot

When I started working on my app idea, I wasn’t sure how long it would take — especially with only a few hours a day to work.
But surprisingly, I launched my MVP in just a few weeks. The secret? Treating ChatGPT like a teammate.

Instead of vague prompts, I gave it clear roles:

“You’re a product manager. Help me define the user flow for an app that recommends lucky numbers based on daily emotions.”

The results were structured, thoughtful, and fast.


Breaking down tasks for faster Building app with ChatGPT

Rather than asking for entire apps, I broke everything into micro tasks:

  • “Write a function that generates a lucky number.”
  • “Suggest a concise app description for the Play Store.”
  • “Design a single-screen UI flow with 3 buttons.”

This helped me stay focused and productive, even in short sessions.


Creating reusable templates and launching faster

For test-style apps, I built a reusable logic engine — questions, scoring, and result text were just data.
It became easy to release new versions by swapping out content. This modular approach saved me days of work.


Speed over perfection when Building app with ChatGPT

My first app wasn’t perfect — rough UI, simple ads, basic logic. But I shipped it.
It gave me real data and user feedback.
I wasn’t chasing perfection; I was chasing progress. And using ChatGPT helped me get there.


Final thoughts

Building apps with ChatGPT has completely changed my solo workflow.
I can move from idea to prototype quickly and confidently, with surprisingly few obstacles.
The best part? I’m not alone — even when I’m working solo.
Thanks
