“As apps go, only Enfour’s American Heritage Dictionary stands out for its graphic appeal and functionality. Although I was pleased to have so much lexical firepower in such a compact form, I was annoyed at how poorly the other dictionaries present on the platform.”

Editor’s Choice. ranking = “Great”

(and these were for just version 1.0!)
