What is an IQ Test?
---------------------------------------------------------------

An IQ test is used to show how "intelligent" you are in relation to other people. But what is intelligence? This is not a defined term and so intelligence is just what an IQ test measures. Therefore, different IQ tests can not be compared, just the same test, and it simply tells you if you have solved the tasks better (over IQ 100) or worse (under IQ 100) than the average. So do not take the IQ that seriously, just test how you cut off compared to others! This app is also developed for brain training.

---------------------------------------------------------------
Brain booster and brain training
---------------------------------------------------------------

To improve your brain performance, we have added numerous tasks and exercises in the IQ Test app that will increase your performance. So if you are about to take an employment test or a psychological test, you can use it to train your brain and get a better result. The tasks are not only in the IQ test area, but also help to improve logical thinking, math and more.
