All you have to do to start learning and memorising vocabulary is download this app and set how many notifications do you want to receive and when.
Words App will schedule notifications in the interval you set. Which means you don't ever have to open the app again! Simply do whatever you usually do and when you receive notification with Word to test, choose the correct answer from available options.
Our Spaced Repetition Algorithm decides when is the best time to study the Word. You will never forget the Word again, but also you will not study the Word too often.
You can also use Words as a quick dictionary. Simply swipe down on home screen to open Spotlight Search and start typing the Word you search! It works with Pronunciation and Translations too.
