July 20, 2007: Only a month after the unique iPhone goes on sale, the primary third-party app will get compiled and launched for the brand new platform. The Hi there World app serves extra as a proof of idea than a critical instrument. Nonetheless, it clearly demonstrates that third-party apps will change into a cornerstone of the brand new iPhone economic system.
It’s a disgrace Apple doesn’t get the memo.
Hi there, World! packages and the Hi there World app
“Hi there, World!” packages are easy demos used to point out off a brand new programming language or exhibit the chances of a brand new platform. The very first “hi there, world” (minus the capital letters) program reportedly got here from a 1974 inner memo from Bell Laboratories about coding utilizing the lab’s then-new C programming language.
The Hi there World app from 2007, which merely flashed phrases on a display screen, gave many customers their first peek on the iPhone’s future.
It additionally appeared like a pleasant nod to the previous. It recalled a convention born of the unique Macintosh 128K demonstration 20 years earlier than. When Apple co-founder Steve Jobs debuted the Mac in January 1984, he showcased a text-to-speech means that permit the pc say, “Hi there, I’m Macintosh.” And when Jobs returned to Apple within the late Nineties, the slogan chosen for the breakthrough iMac G3 was “Hi there (Once more).”
Given the iPhone’s concentrate on connectivity and communication, increasing “Hi there” to “Hi there World” appeared logical.

Hi there World and the rise of native iPhone apps
A hacker going by the title Nightwatch developed the Hi there World app that confirmed off the iPhone’s potential. The straightforward demo grew to become large information on the time as a result of Apple had not launched an official App Retailer, launched an iPhone software program growth package and even bothered to say whether or not these strikes have been within the playing cards.
Inside Apple, a debate raged concerning the iPhone. Ought to it change into a generative platform, with third-party apps, or stay locked-down? The principle defender of the second possibility was Jobs. He feared that letting builders put native apps on the iPhone would sound the demise knell for high quality.
Jobs didn’t again down till early 2008. A number of months after that, Apple opened the doorways of its iOS App Retailer.
The world of janky net apps was coming to an finish. Actual native apps have been on their manner!
The App Retailer: A stroke of genius for Apple
The choice proved good. All through 2024, Apple estimated the “app economic system” generated $406 billion in enterprise in the US alone.
The truth is, lower than 20 years after the Hi there World app arrived, the App Retailer has confirmed so profitable that it’s drawn the eye of antitrust regulators in the US and around the globe. Europe’s Digital Markets Act, handed in 2022, introduced sweeping modifications to the App Retailer (and thus the iPhone itself). That features sideloaded apps and different app shops, amongst different issues.
