IO Classroom, formerly known as Skedula, is an Android application developed by Illuminate Mobile. It is a teacher tool that helps to manage the classroom and view student data. This app is designed for teachers who teach a class and require a login to access the features.

The IO Classroom app offers several features such as class listing, attendance taking, grading assignments, bulk grading, and gradebook. Teachers can add or edit assignments and view all grades for all students. The app also provides individual student profiles, including contact information, daily attendance, and anecdotal records. Teachers can access these profiles from any seating chart, gradebook, or search for a specific student. Additionally, the app has a mail feature that allows teachers to view and compose messages within the app.
