If you go to the URL (http://readerplates.com/iPad) you will find a section for the iPad.
I assure you that Reader Plates exists for the iPad, I have it on my iPad!

I recently subscribed to “Reader Plates” for the iPad (http://readerplates.com/iPad) so far, I like it very much. The cost is $9.99 per month and all the data can be downloaded directly to your iPad using WiFi.
>>> Their Web site states:
At this time Reader Plates are available only for the Sony PRS-505, PRS-900, PRS-950, and the Amazon Kindle DX electronic book readers. <<<
