---------------------------------------------------------------
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 Test Brain Training Riddles Reviews in United States

### *---- "Absolutely awful rip off!"
Find another IQ test. This is absolutely terrible. Pretty sad that you have to pay money to take an IQ test—-on the Google play store. It’s a rip off and the makers are greedy. As soon as you download this app, they will be asking you for money. I’m glad I only struggled for three minutes with this garbage app. I will never download it again—-uninstalled! Good luck, making a quality app. This is trash, garbage, nonsense.
-- spholcomb, 2025-08-18

### ****- "Good overall"
My only complaint is waiting on the ads. Aside from that the app is good. Test was challenging, as it should be. My resultant IQ is 131. I have no idea if this score is accurate, but I suspect it is within the realm of possibility. I will compare other IQ tests to see if it lines up.
-- FYI gru, 2025-04-14

### *---- "Answers are wrong"
I am not saying this because I think I’m always right, but some of the questions only had incorrect answers. For example it asked “how many 3’s will I encounter up to fifty”. At first I thought 1, as there is only one three; but that wasn’t an option. My second thought was 5 as there is a 3,13,23,33,43; yet that wasn’t an option either. So I did 50 divided by 3, which is 16.6 recurring; but 16 wasn’t an option. The only choices I had were 11,13,15,19 so I chose 15 as it was the closest. And it was the correct answer!!! Of course the explanations are hidden behind a paywall so I couldn’t even see their reasoning.
-- :Isabella, 2025-03-27

### **--- "Eh"
Too many ads & you have to pay to 
A. Not be timed
&
B. Learn the correct answers 
👎
-- Trnkets, 2025-03-18

### *---- "I hate it"
I can’t even go to the next question and I can’t even delete it on my iPhone
-- Hi name123, 2025-03-08

### *---- "hate it"
First of all, having to pay for not being timed is TERRIBLE. I struggle so bad on questions whenever it’s timed, and it is unfair for the people who take a long process time than usual people. Next, It doesn’t give you the solution on all the wrong answers, you have to pay to be able to get the actual answer which is awful. This IQ test is NOT disabled people friendly at all either, and again with the time limit, not getting to use your knowledge to your full extent because of seeing that TOO LOW OF A TIME LIMIT, can harm certain peoples mental health for seeing a low score. definitely not recommended, get another app.
-- Cool_Viking, 2025-02-26

### **--- "Free Version - NOPE"
Free version is way too restrictive ànd pop ups are out of control.  Pay version is the only way I would recommend it.
-- kdove0304, 2025-01-10

### *---- "no results"
so l dont know about this app before paying. no explanations. despite watching many ads. has many different languages. could be a scam.
-- Green engine, 2024-12-29

### *---- "This app is very bad"
This app doesn’t make any sense, the exercises are extremely bad designed. Also the prices look like a scam. Totally not recommended.
-- Sabin Hantu, 2024-09-13

### *---- "Everything is for pro members"
Basically, everything in this app is for pro members. Meaning you have to pay. Im deleting this app. Would NOT recommend
-- Andrew the rewiever, 2024-08-21
