No one makes one. The screen E-Dope uses was designed to be used as a merchandise tag in a department or grocery store. E-Dope did not make them, they're off the shelf. The screens are really cheap when a store chain is buying millions of them. More when you buy small quantities, but you still get the cost benefits of mass production.
The issue is with Apple devices. Apple requires every device that tries to talk to one of their devices to have an encryption chip in it that must be bought from Apple. It's a relatively small cost adder (a dollar or two) on an expensive electronic device, but a relatively huge one on of these screens that are probably only a couple dollars in high volume. There is no reason to add that cost and no reason to use an Apple device in the application the screens are made for. So, you will likely never see one for Apple devices. If someone wants to make a dedicated device for iPhones, they can. But the end device is going to cost hundreds more because it won't be made in anywhere close to the volumes the little screens are made in.
