The Hiya World app serves extra as a proof of idea than a critical device. Nevertheless, it clearly demonstrates that third-party apps will grow to be a cornerstone of the brand new iPhone economic system.
It’s a disgrace Apple doesn’t get the memo.
Hiya, World! applications and the Hiya World app
“Hiya, World!” applications are easy demos used to point out off a brand new programming language or exhibit the probabilities of a brand new platform. The very first “whats up, 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 Hiya World app from 2007, which merely flashed phrases on a display, gave many customers their first peek on the iPhone’s future.
It additionally appeared like a pleasant nod to the previous. It recalled a practice 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 capacity that allow the pc say, “Hiya, I’m Macintosh.” And when Jobs returned to Apple within the late Nineteen Nineties, the slogan chosen for the breakthrough iMac G3 was “Hiya (Once more).”

Hiya World and the rise of native iPhone apps
A hacker going by the title Nightwatch developed the Hiya World app that confirmed off the iPhone’s potential. The easy 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 improvement 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 grow to be 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 loss of life knell for high quality.
Jobs didn’t again down till early 2008. A couple 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 america alone.
In truth, lower than 20 years after the Hiya World app arrived, the App Retailer has confirmed so profitable that it’s drawn the eye of antitrust regulators in america and all over the world. Europe’s Digital Markets Act, handed in 2022, introduced sweeping adjustments to the App Retailer (and thus the iPhone itself). That features sideloaded apps and different app shops, amongst different issues.
