My friend needs to make some training, self-assessment quizzes for their staff, think of A)B)C)D) ones. Ideally this should be a mobile app or a mobile-friendly website. The app must show whether the reply was correct or incorrect right away. So far I’ve only found Typeform (too powerful for the need) and a bunch for obviously-for-kids quiz maker websites. I’m wondering whether there are cheaper alternatives to Typeform made just for quizzes.
