Beepboop, a language-learning platform, created its own web app to improve the learning experience for its students. The traditional video conferencing software was too slow and inflexible, so Beepboop decided to develop an audio-only web app that streamlines classes, resulting in 40% more speaking time for students. This decision was driven by limitations of traditional video conferencing software, which had poor quality and required fast internet connections. By building on Daily's APIs, Beepboop developed a performant audio-only web app with intuitive controls, guiding instructors through class and telling them who to call. The new platform also supports observers, who can participate in classes by giving feedback to students or testing their knowledge with multiple-choice quizzes. With the support of Daily's APIs, Beepboop has reduced development time by 90% and is now perfectly situated to build more features on top of Daily's infrastructure, expanding access to unlock business potential.
