Here are a couple of recent threads on the same topic:
"Updated" ER App for IPAD
IPhone ER App Update - Too Cumbersome to Use
So, I'll close this one and please feel free to continue on one of those threads. One of the suggestions in those threads that you might want to consider, is using the mobile style available in the "Style Chooser" down at the bottom of the page on the left. Janet's posts in those threads explain more about it.
