Cloudents has developed a new iPhone and Android app that allows you to rate your professors.
GradeBack is designed to put the power in the hands of students. The app uses Facebook data to determine not only what university the user attends, but what professors would be most relevant to them. With an interface similar to Tinder, GradeBack allows users to anonymously swipe through a cache of professors and grade them by selecting a preset rating. The app then calculates user's ratings to come to an average score, which will hopefully help students in making crucial decisions about their timetable.
Currently, GradeBack boasts an extensive database of over 1.5 million professors who are up for grading.
