Mondly
Mobile app for learning vocabulary

Mondly is a multilingual mobile app with more than 40 languages. The student can choose which languages they want as their target and support language pair, which means they can study using their native language. The content includes short lessons, dialogues, and glossaries. The topics are practical, such as visiting a restaurant and travelling. The lessons are short and the app also has a hands-free feature, which is ideal for even the busiest of students. Fairly precise speech recognition enables pronunciation practice, and the student can also chat with a bot. Mondly has also published a separate Added Reality (AR) application, which is a fun addition to studying. Author: a company.
