RhymeX could help to find a rhyme to any word - even for imaginary word!
Just enter a word in the search field to find rhymes for it. There are a lot of options to improve your experience with the application including "Favorite rhymes" section and "Search History".
The "killer feature" is navigation from rhyme to rhyme just in one touch.
And the best part - everything is working offline!
By the way, you can manage your history and favorite rhymes and decide what to save and what to remove.
You can manage your main screen from the Settings and apply changes on the fly!
