7Things is unique mobile application that saves short texts into your memory. No black magic, though :) It uses spaced repetition and three types of exercises to help you memorize whatever you want.
* Use live texts in English, not static content
* Produce grammar multiple choice questions for learners automatically from texts
* Get diagnostic information on type of errors learners make
* Diagnostics tells was it a grammar, meaning or spelling mistake
* Each sentence is tagged with a CEFR level
