Student Help Queue System

Problem Description

When students are working and need help, they raise their hands or shout my name. But when more than 3 people need help at the same time, it becomes a competition for who can get my attention first or loudest. The ones who don't want to compete decide it's not worth asking for help. I have a queue on the board for them to write their names, but they don't want to write their names and ask me to do it for them.

Proposed Solution

I want an app they can access from their computer that puts them on the list and tells them what number they are for help. Then an app for my phone that shows me who's next and I can easily take them off. Also, I can reorder them if possible. Would also be great if I could personalize the message that tells them they're in the queue that has instructions or hints for what to do while they wait for my help.
