5 Movies, likely the first iPhone app generated almost entirely by ChatGPT, was approved by Apple and published on the App Store late Thursday night.

Morten Just, an independent developer of Mac apps who’s based in Switzerland, guided ChatGPT through the creation of the movie-recommendation app. Just said he told the AI what he wanted, then pasted its output into an Xcode project, writing only an estimated 2% to 5% of the code himself. The chatbot even fixed bugs as Just pasted in error messages.

“What matters to me is creating software that is useful and solves real problems,” Just told Cult of Mac after his 5 Movies app went live. “If I can do that faster with AI, I will.”

Planet of the Apps is a series of interviews with app developers about making, marketing and maintaining apps in the App Store.

Swiss developer Morten Just has built a whole slew of useful Mac apps under the name Otato. But his latest app wasn’t made by him at all: He asked ChatGPT to build it for him.

While Just earned his stripes as a professional programmer, he didn’t write a single line of code to create 5 Movies. It’s an iPhone app that gives you five daily movie recommendations, shows you the trailers on YouTube and tells you where you can stream the films. (It’s currently pending App Store approval.)

These days, artificial intelligence is making headlines for giving users powerful tools that can write essays, recreate impressive art and give technology journalists the heebie-jeebies. 5 Movies is proof that, with a big assist from AI, it only takes a few prompts and a basic understanding of Xcode to create an iPhone app without any coding yourself.

When I interviewed Morten earlier this week for Cult of Mac, I asked him how he got ChatGPT to build his app, what the generated code looked like, and how AI-coded apps will impact ordinary people as well as software developers.
