Great app for so many reasons

I love challenging quizzes that incorporate the ability to deduce answers unknown by using hints that are found within the questions. This is really much more thought out and related to IQ testing than most trivia type apps. I actually purchased the IQ app first from this company before being aware of this app. I especially enjoy the vast variety of easy to very difficult referenced knowledge that is excellent for anyone who is looking for something to learn from and enjoy the whole process.

The Best

Out of all the trivia-type apps, Knowledge+ stands alone. It is well written, broad in scope, and truly challenging. Also, being able to see your true stats is a plus, and the Strengths and Weaknesses part is great for improving in specific subjects. Not for the academic wimp, but it’ll help you become less of one—- I play Knowledge + far more than any other game or app.

Fun, and helps one get smarter!

I enjoy this quiz, playing it many times each week. If you do well, then the numerous categories will not dissuade you from moving on...but if you fail often you will not want to tell your friends about it! report here!
