Hi Sweetmom,
Little Reader Touch for the iPad is completely different from Little Reader for the PC. They do not have any connection with each other, and as such, you cannot access your customized categories on the iPad app.
In case you haven't, you can go ahead and directly download Little Reader Touch on your iPad from the app store. You don't even need a purchase to get it, since the app in itself is free.
The only things you need though - if you want the English courses on the iPad - is iAccess and a Little Reader PC license. I can see from your record that you already have a Little Reader PC license, so this just leaves iAccess.
The app has the basic features which the computer program version of Little Reader has; but it cannot do everything that the PC version can (such as edit lessons, create new lessons, and download your customized lessons from the PC to the app, etc.)
I hope that this information helps.
