From StudyStack:
Since 2002 millions of students have used StudyStack to memorize
information. StudyStack's community of students and teachers have shared
millions of flashcards. For each set of flashcards entered, the StudyStack
website generates over a dozen ways for users to study the information they
need to learn. The variety of study activities enables users to memorize data
quickly without getting bored from using a single method of study. StudyStack
enables teacher to quickly enter data once and have a dozen different
activities created for their students to memorize facts.
StudyStack's founder, John Weidner, started the web site as a hobby out of
his desire to contribute to the educational community. StudyStack has operated
as a free advertiser supported business - which is the price preferred by most
students and teachers. In 2013 StudyStack launched a PRO membership for users
who want to be able to study without the distractions of advertisements (plans
for $1.50/month, $10/year, and $20/year). StudyStack's plan for the future is
to continue to add innovative ways for users to study both on the StudyStack
web site and with apps on tablets and smart phones.
