7 day free trial of Adobe acrobat DC not working

I have a document I need to print. I got the 7 day free trial of Adobe acrobat DC, downloaded the app (on both my iPhone and my iPad), but when I try to open my document it tells me "This form requires Adobe Acrobat Reader DC for Mac or Windows". I thought that's what I downloaded? There is no other app to download. Will this just not work on my iPhone or iPad?
