For teachers, schools and tuition centres
Classes, your own quizzes, worksheets, live quizzes and insights are free for everyone. Verified teachers, lecturers and tutors get Pro free: ask from Classes → Bondline for teachers in the app.
A centre licence gives the students in your classes Pro while they're enrolled, from US$3 a student for 5 months. It covers every class you teach, up to the number of students you choose in each. Buy it by card in the app (Classes → Bondline for teachers), or ask for an invoice and pay by bank transfer.
