Undependable

This works ok on my iPhone but not on my iPad
I had settings set on sharing info with my iPhone and iPad but app did not do so.
Do I reinstalled it on my iPad.
Kept getting message that "the list already exists"
Which it did not.
I tried reinstalling it. Same problem
I finally deleted it from my iPad
The frustrating part is I cant find any other user friendly list app
