With this, you can start making digital copies of your flash cards, then pull them up at a computer and study. It works wonders! First you're going to need to type in or copy/paste your info. After you have enough content, just click on 'Start Study Session', and learn.
Now it just doesn't end there, but it goes farther, much farther. You can help out your fellow classmates by giving them the link, which I plan to do for my classes. Just give them the link, and go from there. No sign up needed from your peers.
The coolest thing about having flash cards in the cloud, is the fact that you can upload them to almost anything. There's a mobile version of Flashcard Machine for iOS, and Android devices. And it works just as well. Granted, they do cost $1.99 for the Android version, but the iOS version is free.
Try it out!
