Are you never sure what time class ends?
Now there is an app for that.
Its got home screen widgets, lock screen widgets, and a watch app with complications. You will never be confused again about when class ends. It will automatically adjust for the normal changes in the weekly schedule and there is an override option in the app for unexpected changes like activity bell schedules and two hour delays.
This app was custom built for the students and teachers of Kennard-Dale High School.
