Over 1,000 English idiom flashcards for your smartphone!
PROS: In its current iteration, IdiomLand offers 1,000+ fun, engaging and retro-designed idiom vocabulary cards and examples. Unlike most idiom lists you find on the web, Idiom Land only includes idioms that native speakers actually use. If you’re in doubt, just browse through the video cards where you’ll see these very idioms used in some of the most popular films made in the English language.
CONS: It’s only a supplemental tool and won’t help you develop fluency in English.
