Key Features of a Language Learning App

To Build Language Learning App Like Duolingo and make it popular, you need to add some core features to it, and below are some of the most popular language-learning apps.

  1. Login and Sign up

If your language learning app offers a variety of courses, it will become popular compared to the app, which offers only a few courses.
  1. Progress tracking
  2. The best thing about language learning apps is that they help learners celebrate their achievements, and progress trackers are the best tool for this purpose. Each student’s weekly and daily rating motivates them to use the app, again and again, to boost up their knowledge.
  1. Video and Audio Lessons
  2. All the good language learning apps feature audio and video lessons to improve the learning experience. Users can easily stream audio and video lessons online or download them to watch them whenever they want without an internet connection. Their pronunciation will become better if they listen to native language speakers every day.
  1. Integration with Social Networks
  2. Students can directly share their achievements with their family members with social media networks integration. They can also enable the one-touch login feature to use their social media accounts to log in to the app instead of email and password.
