Biz Law In A Flash is the perfect flash card application for someone on the go. Study your card stacks in your little breaks throughout the day. I remembers what you swiped right (mastered) or swiped left (not mastered). It even remembers where you left off, so there's no starting from scratch. Need to create your own card stacks? Maybe you need to make your own stack from other card stacks. Not a problem. Biz Law In A Flash allows you to create your own card stacks from scratch or from other card stacks.
