Well designed app, Let down by the questions

The app generally works very well, and is easy to navigate using gestures. The different voices and the music and the sound affects all add to the overall fun of the game. It is really well done as far as the user interface design is concerned.
There are a couple of suggestions I could make for improving how the game works. First, there needs to be some way of getting the game to repeat the question. Second, the text of the question should be displayed on the screen, so that the user can have a way of checking the spelling of difficult words.
However, the game is seriously let down by the quality of the questions. I am particularly interested in geography, and I noticed that the game had a pack of 6,500 geography questions available as an in-app purchase for £5. This sounded like good value, with the promise of many hours of quizzing on one of my favourite topics. So I bought it. But it took only a matter of a few rounds of the quiz for serious flaws to become apparent.
First, no attempt has been made to make questions more difficult as you get nearer to the £1 million prize. It seems that the difficulty of the question is entirely random. I have been asked a much too difficult question for the £100 prize (708 is the area code for which country?), and a much too easy question for the £1 million prize (if someone from Australia is called an Australian, then what is someone from New Zealand called?). This randomness of difficulty hugely spoils the game.
Second, some of the questions are simply bizarre. For example, in a geography question, I was asked which country singer appeared in a particular film, and the two options were Glenn Campbell and South Africa. As a second example, I was asked in what US state is the city of Baton Rouge? The options were something like Louisiana, Seychelles, South Africa and Cologne (or some such list of absurd possibilities along with one obvious answer.
Third, some of the questions referred to countries which have not existed for decades, for example, West Germany, Czechoslovakia, and The Belgian Congo.
Fourth, there are far too many questions about volcanoes.
You very much get the impression that the author found a database of geographical names and their categories, and used an algorithm to generate a whole bunch of questions. If so, the algorithm evidently did not work very well. It is evident to me now that the geography pack I purchased substituted quantity for quality.
After just a few days of using the app, I have given up on it. I feel that I have wasted my money.
It would have been a great app if the questions were much better.
