When you are not using your phone, only the time can be seen on the splash screen (or lock screen). By using this application you can see and learn English words and their translation. At the same time, your brain perceives new information in the background and in 2-3 weeks you will already know more than 4000 words. This vocabulary is enough for communication on almost all topics. The built-in text-to-speech engine in your phone speaks words, which allows you to perceive information by ear, while doing what you love.
