Yes. If a student receives an emergency call or text during class, he or she can go and answer it. The app provides a "60 Second Unlock" button (right) that can be used once per Flipd session. The student can use their 60 seconds for an emergency and it will not count against their Total Flipd Time if they return to Flipd within the minute. Due to the unexpected nature of emergencies or important messages, we think it's fair that students have this opportunity to respond or reply without a penalty, though it's important that instructors emphasize that students exit the class to do so.
This is what makes Flipd an appreciated and powerful alternative for students who are reluctant to power off their phones for class in case of emergencies or important notifications. It also adds to the Flipd learning experience, where students begin to learn how to filter what is important from what is a distraction.
