Important: "Stone Fish" is a kind of real fish living under ocean, not any random fish made by stone. Please google "stone fish images" for details. We're building a web app to help middle-level english learners to create their own list of vocabularies and phrases (those they find hard to remember or use). Once the list is created (can be modified anytime of course), this app will choose a word/phrase from the list and push it to the user's mobile phone every 30 minutes, so as to help the user the remember the list better and better, until one day he removes every item in the list.
