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.

IQ Quiz

This IQ Quiz will definitely provide any individual with an abundance of time they can spend learning to develop skills such as: spacial reasoning, pattern recognition, and vocabulary analysis. This app’s ability to challenge a person and keep him/her/them intellectually engaged is astounding. The creators of it allow for explanation of each solution and give understandable reasons behind each answer. An individual’s intellectual abilities will certainly be tested, which is precisely what I was looking forward to. I enjoy that you are given options to develop and define your study and practice techniques. Some options do require in-app purchases. However, there are certain options fully free and available without needing to make any purchases or subscribe to anything which is nice if you just want to learn an approximate score for your IQ, compared to others. Hope you have an awesome time with this app!

Bad product

I usually don’t write reviews for the apps I download but this needed a review. I downloaded the app without purchasing the premium package. Right off the bat I see issues with the way the app is written. You should not need to purchase anything to at least see your result after each stage. I’m not asking for details and the answers for each question but the developer should at least give you the statistics and show how you’ve done, at the minimum, with percentage of success. Don’t tell me I did great and amazing after each stage. Be realistic and give accurate comments based on the level of success.
I made my biggest mistake and purchased their so called premium package. Well after going through three different IQ tests now I get the notice that “they are working on new IQ test” and that it will be available shortly. We’ll shortly is now on day 5! I don’t want to pay all this money to seat around and wait for new IQ tests. Shouldn’t an app have at least 20-30 different IQ tests? Why do I have to do repeats when that would not really give me any realistic sense of how I’ve done.
I really have to cut this short as I have many comments about the available “3” IQ tests. Grammar, logic and poorly written questions.
I wish I could get my money back as I made the biggest mistake of purchasing this app.

Absolutely Positively THE WORST...

I didn’t believe others when they told me it’s a waste of time & effort. First & foremost; someone forgot to check all the grammatical errors ; there are plenty as if the developer don’t care about the aspect of teaching people the proper way to develop a sentence!!!! Additionally; you are asked lots of questions and to know the correct answer you must PAY the developer a fee to get to know the answer and why it’s the correct answer. This is messed up..I am NOT saying the developer doesn’t deserve to be reimbursed for his work ; all I am saying; he is going the wrong way about getting paid. You practically can go thru lots of questions without knowing the answers and you play play play & at the end ...The developer tells you : “ you conquered this segment of the test”...Another great deficiency in this game; it’s NOT MADE FOR ALL...Certain people with certain disabilities would be unable to play the games & THATS NOT FAIR...Additionally; I highly recommend developer to hire a third party to go over the grammatical errors. Many subscribers criticize the game and the developer ignores replying to their constructive criticism which truly shows he doesn’t care about what his subscribers think and recommend, an acknowledgement with an explanation from the developer to subscribers will go a long way in building a resilient relationship base with players. I AM OUT AND I AM DELETING THIS APP RIGHT NOW...
