In order for the test to function properly please use the same language you have on your smartphone and read the instructions at the beginning. Currently, you can choose from 5 different languages.
The IQ test is free and reliable. It doesn't require any registration, is very small (under 650kb), and it goes directly to the SD card (in case you have one).
