The platforms track student progress, display statistics, and recommend content based on areas that require reinforcement. - Adaptation to the user level
From absolute beginners to advanced learners, the apps offer personalized learning paths tailored to each individual's prior knowledge and goals. - Zero or very low cost

Duolingo uses algorithms that identify the words and grammatical structures that users forget most frequently, scheduling reviews at the optimal time to consolidate learning. - Community and leagues
Users can follow friends, compare progress, and participate in weekly leagues for friendly competition.
Thanks to these features, Duolingo promotes a daily study habit, which is essential for mastering a language. Furthermore, its free nature makes it an accessible tool for anyone, regardless of their budget.

One of Busuu's main strengths is that users can type texts and record their voices, then other community members (who are native or advanced English speakers) correct and comment on them to improve grammar, style, and pronunciation. - Grammar and vocabulary units
Presented with clear explanations, everyday usage examples, and practical exercises, this helps you understand not only the "what" but also the "why" behind the grammar rules. - Integrated speech recognition
To practice pronunciation, the student repeats phrases while the app evaluates their accuracy and intonation. - Offline mode
Allows you to download lessons and study offline, ideal for travel or areas with limited internet. - Official certificates
With the Premium version, you get a certificate endorsed by McGraw-Hill, useful for CVs and professional profiles.
