Online language classes and mobile-assisted language learning applications (Apps) are non-traditional methods of education that differ from traditional classes, which involve face-to-face instruction and teacher-led lessons. Web or mobile-assisted language learning applications cater to the changing world, making them convenient and affordable for those with limited time. These applications can be used at the learners’ convenience, making them a qualitative leap in the field of language learning. There is a world full of language applications some of which are dedicated to the education of the English Language as the Global language and others have many languages to learn. In the explorations of language applications, the Google Bundle is one of the best for online classes as it is the most comprehensive bundle and Duolingo is the best language application, if we considered the increasing number of its downloads and its continuously increasing revenue. Most of the applications have free and Pro or Premium features, and some only offer a free trial of one lesson or a seven-day trial. Each application has different teaching methods; some use gamification, interactive exercises, communicative approach, spaced repetition, contextual learning, audio-visual learning, and personalization. Moreover, most of the applications employ Artificial intelligence (AI) for immediate feedback.
