A bit of brain traning but not to be relied upon.
So the pros to this app is the amount of content. They have alot of conundrums to solve ranging a bunch of different categories. The cons however is that the app is poorly executed, even sloppy. Some of the answers are demonstrably wrong and the IQ test is highly unreliable. I got a result of 160. Flattering yes but I know for a fact that I am between 115-130 so if you are looking for an accurate IQ-test this is not it. For som brain exercise pass time I guess this app is OK.
