Trivia: Knowledge Trainer is the quiz app for smart people. It’s designed to stimulate your brain with over 6,000 high-quality, challenging, and informative questions.

Each lesson tests your wits with 10 questions from 10 different categories. The difficulty level depends on you: get an answer right, you'll move up a level. A wrong answer leads to an easier question. But you'll want to move up to improve your Knowledge Quotient, recalculated after every round.

Just amazing

This app is fantastic! I am no wizard nor do I have and an iq over 100. I don’t have to pay for using this app and it teaches my so Much. Difficult questions for me at times but it gives me the opportunity to improve my knowledge and I truely believe it works! I love to learn and learn new stuff everyday with this, I highly recommend to anyone that wants to improve or test their knowledge. Well done to the curators. All the best. Nat x

Good app

Love this app - Knowledge is great to make you “think” if even though there is multiple choice answers. There’s a wide variety of questions and I never get bored - highly recommended and I don’t mind the adds as they’re not on the screen long enough to be annoying. I play this all the time and I love it!!

Knowledge Trainer

I did like this app but in the middle of a session it can turn off. When I go back I have missed my turn. This can happen a few times in one session. Can it be fixed please?
