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.

2020 marks the 10th anniversary of this sophisticated trivia app. Since 2010, the game has helped more than 7 million players to improve their general knowledge. Our worldwide team is continuously improving and updating the app.

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.

More app features:
• 6000+ questions = fewer repeats
• 5 difficulty levels, 10 general knowledge training categories
• American, British, Australian & international gameplay modes
• Review function for missed questions
• Save game progress for 1-3 players

Improve your general knowledge with regular training. You can review category-specific statistics as you go to see how you have progressed after each quiz round.

Knowledge trainer

So fun and i learn trivia all sorts of things

I think it’s pretty lame that the game only allows one new set of questions per day. It wasn’t like this before. Probably going to uninstall. ✌️

Developer Response ,

Hi, thanks for reaching out to us. We can understand your frustration but in order to continue to offer Knowledge Trainer as a free app, (after 20 free lessons) we ask you to watch a video Ad in return for a free lesson for the day. This helps us cover our costs of providing and maintaining this great app, and keep our small but hard-working business running :) Alternatively, you could support us by upgrading to Premium and enjoy unlimited questions and an Ad free experience. If you still think both options are unfair, please let us know and email support with any suggestions you may have. Kindly and respectfully, the binary family

Paid version still shows ad's - updated!

Update: I deleted the app completely, downloaded it again and reinstalled it - no ads. Thanks.
I don't want to see ad's when I have upgraded to the full version. So please take them off. It's annoying.

Developer Response ,

Hi M. Kanka, we're very sorry you're having some trouble- there should be no ads with a full version upgrade! Please contact our support team so we can help you get the ads removed.
