Duolingo is arguably the most recognized language learning app, known for its game-like interface that makes starting a new language feel fun and accessible. Through points, streaks, and leaderboards, it excels at motivating users to build a consistent daily practice habit. The bite-sized lessons are ideal for learning vocabulary and basic sentence structures on the go. However, the platform offers weak explicit grammar explanations and limited opportunities for real speaking practice, meaning its content can feel shallow for those aiming to move beyond a beginner level. It serves best as an engaging starting point or a vocabulary-building supplement.

Cambly specializes in on-demand English conversation practice. At the press of a button, the platform connects you with a friendly native speaker for a video chat session. This model is ideal for learners seeking to practice speaking without the scheduling of a formal lesson. Cambly operates on a subscription that provides a set number of minutes per week. While some tutors offer structured lessons, the platform's main strength is its accessibility for spontaneous, immersive conversation to build fluency.
