Why can't I download the iOS app here?
Apple runs a walled garden with one gate, and they're the shady bouncer pocketing the cover charge to let you in. They've built an entire business model around taking a cut of everything that goes through their App Store, and they've made it deliberately hostile to install software any other way. Imagine a landlord who charges you rental feels to lease furniture, and charges you more fees if you try to bring your own.
Places like the EU and Japan have been pushing back on this anti-competitive behavior, and there are ongoing policies and cases that might force Apple to allow third-party app stores and sideloading on your phone, too. But for now, in most regions, Apple maintains their stranglehold on what you can install on your own device.
Not all hope is lost: If you have a Mac with Xcode, you can sideload using your own Apple Developer account (free tier works). Or download the simulator build for testing:
Let me know if you feel strongly enough about Coppelia for iOS to pitch in for the $100 USD annual Apple Developer fee to be permitted to list an app on Apple's App Store.
