Find the right word wherever you go. The official RhymeZone iOS app is a fast, powerful rhyming dictionary and thesaurus that you can use anywhere, even if you're not on the net. Quickly find rhymes, near rhymes (including slant rhymes), synonyms, antonyms, homophones, similar sounding words, words with the same consonant pattern, and other related words (generalizations, specializations, words appearing in the same context). Use Apple's local dictionaries or ours online if you are unsure of any meanings. You get a database of over 150,000 words and phrases right at your fingertips. Find rhymes without an Internet connection, but if you are online, we'll connect you to RhymeZone.com for definitions and all the other great features you've come to love, ad-free! Or you can look it up on our sister site, OneLook.com, or even hear it pronounced with your device's built-in text-to-speech. There's also a nifty "Poet Maker" feature, which lets you find words that match constraints on both rhyme and meaning at the same time. For example, suppose you want a word that rhymes with "cat" and means "heavy"; this feature will answer "fat" in no time. Or suppose you're looking for a rhyme of "curious" that means "invalid"; you'll get "spurious". You get the idea! So whether you're aspiring to be the next Shakespeare, looking to put on the finishing touches of a love poem, bust out the next rap lyric, or just seeking some clever wordplay for your English assignment, give the app a try!
