Brainscape is a wonderful site/app that allows teachers or students to create flashcards. These flashcards can be created online and then shared to any iOS mobile device. Best of all these cards can: contain images/audio, can be shared, are ideal for mobile learning, and can be used by any subject.
I highly recommend checking out Brainscape by clicking here!!
I'd like to thank Larry Ferlazzo's wonderful blog for the tip.
