The app is designed as a game that helps users learn English step by step, starting with the simplest tasks and gradually moving towards more complex ones, with exercises built in a special system. Si16's methodology is different from other language learning apps, as it helps users connect all the knowledge they have acquired and imparts the skill of intuitive work with the language structures. The app offers personalized learning programs, allowing users to learn English at their own pace, anytime, anywhere.

The app is suitable for anyone who wants to learn English from scratch, including children. Si16's approach is to make learning a fun game, with no homework, and to inculcate the automaticity of basic language structures in different situations. The app is free to use, but there is an option to buy access to additional lessons using points earned by watching short promotional videos. Si16's methodology is based on the principle that learning English should be enjoyable and not boring, and the app's effectiveness is enhanced by its use of videos to break up the learning process and make it more engaging.
