Fun and informative

Unlike some exam questions where you might be able to figure out the answer based on clues in the question, this trivia app relies on prior knowledge in most cases. For some questions this can be annoying (like for movies, books, or art where it’s either you’ve seen it or you haven’t). The review aspect of the game where you go over missed questions is interesting, but I think it should be recommended to the user once they’ve missed a certain number in a category. Additionally, for missed questions in particular, elaboration on the question and why that answer is correct would be useful in actually teaching the information. As it is, the game reinforces memorization more than true learning of a concept, but as it is a trivia app this is permissible. As far as ads go, they are fairly unintrusive and do not take away from the experience. Overall I am enjoying my experience with this app and would recommend it to a friend.

Problem with this game

Hi, my name is JJ. Are used to play this game. However, is not user-friendly anymore. Are used to tell me which buttons or whatever or any category tap on it would tell me what it is. However, it doesn’t work anymore. This game used to be a lot of fun to me. And I love it because I can learn a lot of things. However, it has changed. It worked when I had my iPhone 4s, it worked when I had my iPhone 6 Plus. It did not work when I had my seven. It’s not working now I have my eight. This game is to be a lot of fun. However, I know the lowest part of this game I give it a zero. Because is not working correctly every time you tapped on the categories, I would tell you what you tapping on. And it’s not working like it should anymore. So why do you have this game, if it’s not user-friendly for me. Are used to play it a lot. So therefore, I think this game is a scam. Because it’s not working. So either you fix it, either people are spending their money for the wrong reasons. To play this game that people can learn from. It’s not working correctly. So until then, I’m not downloading his game until it is fixed.

Developer Response ,

Hi JJ, thank you for your review. We unfortunately had to sacrifice VoiceOver compatibility when we did the last major update to our app to make it compatible with both Apple and Android devices and available to more users. Should it become possible in the future to enable VoiceOver for universal apps we will be sure to implement that feature.

Fun and informative, with some puzzling limitations

This is a great app that will keep you entertained for hours. It's clean and well designed and there are 10 categories of questions, so a good variety of topics. My only complaint is that some of the categories are pretty limited in the range of questions. Sports is particularly puzzling -- most of the questions are about the Olympics, and many are about golf. I'm on round 50 and I haven't come across baseball, soccer, cricket, basketball, ice hockey, or football. They should really expand to some areas outside the Olympics and golf.

Also the Music and Film categories focus a bit too much on who won various awards. Not really something I care much about, even though I love music and film.

That said, this is the BEST trivia app I have come across, by far. In fact I'm going to stop writing and go play some more right now.
