Mingles is a new way to teach and learn English through social interactions. It allows English teachers and students to connect flexibly based on their schedules and interests. Teachers can create their own Mingles classes and earn money from students attending, or they can confirm attendance at classes proposed by students and earn payment from Mingles. Compared to traditional English academies, private lessons, or language exchange meetups, Mingles offers more flexibility and social interaction at a lower cost while still providing professional English instruction. The Mingles app facilitates teachers creating classes, students selecting classes, and payment processing to make English learning an enjoyable social experience.
