The description is written by the software developer. The "Information" section near the end lists requirements for supported devices. iPhone and iPad say "Requires iOS 17.1 or later and a device with the A17 Pro chip or later", and the first iPhones with A17 chips or later are the iPhone 15 Pro and iPhone 15 Pro Max.

I like how when I first opened the link, App Store said I need iOS 17.1 or greater.

So I updated to 17.2.

And only then does App Store let me know that it’s not compatible with this device anyway.

Thanks, Apple!

(I have an iPhone 14 Pro.)
