Quizmash is a different sort of quiz app.
This is the official app for Quizmash.com, the crowd-sourced quiz site where you control the questions.
Take a quiz on one of our subjects, and vote on the questions as you go. Those that are voted under minus two by the community are removed from the pool of potential questions.
Add questions on anything you can think of for others to answer. You can tag questions with more than one category so people can mix and match their quizzes.
