Counting Brain Cells is an interesting quiz app which tells you the amount of brain cells you have. You can choose from 4 built-in offline quizzes. But, there is much more content than that. The app has Open Trivia Database integration, so you can configure your own quiz and access over 4000 quiz questions for free. 

The app uses JSON to load quizzes, so you can easily write you own quiz and load it in with the 'Load File' feature, following the template. The app is also open source so anyone can access it for free providing they have a Windows Device.
