Elevator Pitch
This connection app allows students to notify the teacher when they need help with the click of a button.
Description
The StuStatus App allows teachers to set up a session code that can be provided to students. Students add the session and then they can notify the teacher of their current status. When the student touches a status button the teacher is instantly notified of the status. The available statuses are

- Green = I’m working fine!
- Yellow = I need help. I can keep working.
- Purple = I need to talk
