The test consists of 70 questions, organized into thirteen thematic sections. The questions must be solved in a predetermined sequence. The IQ test was developed for single use only. While designed to be enjoyable, its primary purpose is to determine your IQ with the highest possible accuracy.

According to current definitions, intelligence is composed of a variety of different mental abilities. Dr. Reichel's IQ test includes different parts, allowing the following characteristics to be examined:

• Comprehension
• Linguistic ability
• Analytical thinking
• Logic and reasoning
• Abstract thinking
• Working memory
• Quantitative reasoning
• Spatial judgement
• Processing speed and accuracy

The psychologist Dr. Wolfgang Reichel is a renowned IQ expert and the author of numerous books on the topic of aptitude and IQ tests. He has developed IQ tests for leading newspapers and television programs. Working with the team at the binary family, he conceived this test specifically for use on the iPhone.

It's a ? ,

Questionable at best

This test has very strict time limits for certain parts of the test such as the problem solving, logic problems, and the spatial reasoning sections. The correct answers to the questions in the "technical reasoning" section are questionable especially the one about the scissors and the gears. Some of the odd one out questions can have multiple answers depending on how you define the words... Same with the analogies.. I do not think these questions were well developed nor are there enough for each section to be all that reliable and produce accurate results... Scored a 117 the first time and 125 the 2nd... Don't know how me getting 4 hours of sleep plays into that, but on one other IQ test that was actually developed by a psychologist in a book I scored a 132... Not sure how reliable the claims of this app are.

Hi Aqueesh, we're sorry to hear that you didn't get quite the results you were expecting.

stand up! ,


Unlike other iPhone (or really, most popular "do-it-yourself") IQ tests which focus solely on one area or another, this one gives questions in all areas intelligence must be measured in.

Obviously, this cannot take the place of a legitimate psychiatrist, but it does give a good ballpark image of the user's IQ. For example, taking into account test deviance, my own was reported by psychiatrists as between 148 and 153, and this test reported 144 (though I understand it does not test past 145). This is less than one-half a standard deviation's difference (the standard deviation of IQs is 15), which makes this test, in my experiences, a relatively decent measure.

A note of warning, though - knowing your own IQ changes nothing in your life. You're just as smart as you were before you knew.
