Long before to start the development of the «Idioms and Phrases» app, we had analyzed hundreds of similar applications on Google Play.
We have discovered that lots of those apps had thousands of idioms with good explanations.
But none of them taught learners how to use these difficult phrases.
Moreover, we were surprised to find out that there were no tests that could help learners check their knowledge.
So, we came to the conclusion that there are many great apps with idioms that can be used as the thesaurus.
But no app for actual learning idioms.
