8 of 25Makes for a challenging 10 min break from work!
I’ve used this app for many years. It remains my go to app for trivia. Small contribution = no ads. Love it!
Love this game! Sometimes I know almost all of them. Sometimes I only get one or two. I’m learning. Most of all I love to compete against myself and I’m the only one answering!
Great and fun learnt a lot and referred it to many who really enjoy it thank you
This is one of the best games ever devised. It’s great fun, it’s challenging and it’s informative! But most importantly to show the measure of liking this game you must know that this game is addictive.
Fantastic App, use it everyday!
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.
This app used to be fun but it no longer has any sound so you can’t tell when your time is running out. This happened to me three years ago when I had the app on my iPad. I thought they would have for cedar it by now but I guess not.
