Why are people having trouble viewing my forms on iPads

I have heard on more than one occasion that my forms cannot be viewed on an iPad. Is there something that I can do to change this or are the forms not compatible?

Sorry for the inconvenience. Can you please indicate what form(s) are having issues and what kind of problems they are having. I was able to open one of your forms in my iPad 1 (first generation) and open the same with iPad emulators.
