Even with the takeover of technology, I still found most of my college/school enrolled friends using notecards as study aids.
After watching them carry around hundreds of notecards, I created this app to give them access to their notecards anywhere.
You are able to sort your notecards by Semester and then Section - think Winter 2013 and Section 1, etc. Then you can sort the actual notecards into two piles - Known and Unknown, allowing you to continue going over what you are struggling with while still being able to access the cards you are comfortable with - pretty much what you would do with physical notecards when sitting at the kitchen table.
This is built with Python/Django and hosted on Heroku, obviously. It's design is pretty standard Twitter Bootstrap, and definitely has much room for improvement.
The project is hosted on Github at https://github.com/DanHoerst/notecard if anyone is interested in forking/contributing.
Hope you like it.
