Brainscape provides an excellent foundation to students and content-creators such as myself. It solves what I like to call 'study procrastination through boredom'. Long, two-year courses can often be shortened into 200-300 cards, allowing for amazing results relating to last-minute exam preparation.
One of the massive problems that might make other flashcard applications, such as Studies for Mac, more attractive to your typical content creator, teacher or student is the added advantage of a physical, locally stored application. Frankly, Brainscape's web interface is not perfect and the requirement to have an internet connection in order to create cards can be very inconvenient.
Most importantly, in order to attract thousands of teachers and students in other markets, it is important to recognise and act upon the need for subject-, specification- and qualification-specific decks which will ultimately make the difference between one paying user, and hundreds of paying users. If you would like examples of such qualification-specific decks or would like to hear more from the perspective of a content creator and student, please do not hesitate to contact me on firstname.lastname@example.org.
