Rita El Khoury shares her positive experience with the language-learning app Babbel, which she prefers over Duolingo and Memrise due to its focus on practical communication and real-life conversations. Babbel's curriculum emphasizes essential phrases and useful vocabulary, enhancing retention through a flashcard system that includes visual aids, text, and pronunciation. The app offers a variety of practice methods, including grammar guides and audio recaps, allowing users to tailor their learning experience. Babbel also features an AI-powered Speak function for conversation practice, helping users overcome speaking hesitations. While El Khoury notes some limitations, such as the need to switch the app's primary language for different language pairs, she is considering a long-term subscription due to Babbel's alignment with her learning style and its flexible pricing structure.
