How the App Works
When the app first opens, it will ask for you to choose your name. Select your name, and it will take you to the main screen. The database should already contain your name and the lab you are in, so it will be listed. Aditionally, if you pass the the device from one person to another, you may change users by selecting the bottom button with "Change User."
To scan, select the scan button. Then, hold the screen up to the student's QR code. Simply hold the QR code within the camera view and it will auto select it and decode. You can continue scanning different students or you can click done when finished scanning. Scanning the same student will not affect the database, so that is not a worry.
Select the history button and you will be able to view a list of the students you scanned along with their answer to the unique question.
