Good but...
Note: I use the English to English dictionary.
Its a good app for people who dont want to pull out a dictionary every time they see a word the dont know.
However, the definitions should either be shortened or the box should expand to a bigger size to see the definition; the box is to small for some definitions.
Also, for words with more than one meaning, each definition should be separated and numbered. And if a word has different forms, they should be placed with the corresponding definition or listed underneath the definition, stating what form the word is in (verb, adjective, noun, etc.).
