Nevermind. Figured it out. Kind of confusing as worded above, but both apk's have to be installed on your phone, if anyone else gets confused like i did.
Just FYI for anyone interested. Documents to go is currently only $5.55 (normally $29.99) in celebration of Cinco de Mayo (today only). I just picked it up. Well worth the money imo.
