SimpleSign.in makes events—such as large lecture classes, conferences and meetings—easier for both attendees and administrators.
My brother Nate Bleker developed the back-end. We created an Android app, mobile and desktop web app, and marketing site.
When an event host creates an event, SimpleSign.in builds a QR code and passcode which attendees use to sign in.
Attendees can vote using their smartphones instead of raising their hands or using clickers.
Administrators can browse the attendees.
When the event's over, SimpleSign.in sends the administrator a spreadsheet of all of the attendees.
I also created the marketing site.
It turned out nicely.
