Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Fluid IQ test
This app offers a non-verbal, culture-fair IQ test inspired by Raven's progressive matrices. It measures fluid intelligence and abstract thinking through a series of increasingly complex pattern-completion questions. Results provide an approximate IQ score based on correct answers and age.
- Non-verbal abstract thinking assessment
- Measures fluid intelligence (Gf)
- Pattern recognition and problem-solving
- Culture-fair test design
- Gradually increasing question complexity
- Results based on correct answers and age

What does this test measure? This test is motivated by Raven's progressive matrices that got their name according to their creator John C. Raven, who developed them in 1936 as a non-verbal test of abstract thinking. It is a ‘culture fair’ multiple choice IQ test, that measures your fluid intelligence (Gf) – your reasoning and problem solving ability. Fluid intelligence is a core component of (g) – your general intelligence. This test tests the understanding of the complexity of patterns, the ability to store and retrieve information. It provides insight into the ability to observe, solve problems and learn. The test measures only a subset of intellectual abilities. Based on this, valid conclusions can not be drawn about the overall intelligence of the person, the results are approximate. How does it work? The test consists of 54 questions which in turn are gradually more complex. Respondents choose geometric shapes to properly complete larger images. The result of the test is determined by the number of correct answers and the age of the respondent. However, the final score is not linearly related to the number of correct answers. The evaluation of the test is based on a study of a large sample of anonymous results of users of the app in different age categories and is continuously refined. The results are distributed on the so-called Gaussian curve into several percentile intervals on an overall scale from 0 to 160 intelligence quotient points, with the majority of the population according to the Gaussian curve (i.e. over 50%) corresponds to IQ values between 90 and 110. Advantages and Disadvantages • The advantage of the test is its non-verbal nature, which avoids cultural and linguistic discrepancies. • The disadvantage of the test is that repeating it may improve the result.

Live Ord-Historik (Log) • Appen holder automatisk styr på de sidste 10 ord, der er brudt igennem scanningen, så du aldrig går glip af en besked under din undersøgelse. Automatisk Sweep og Hvid Støj • Kontinuerlig, automatisk frekvensscanning med indbygget lydstøj, der simulerer en ægte analog Ghost Box-oplevelse. Haptisk Feedback • Mærk en fysisk vibration i din iPhone, hver gang et ord bryder igennem scanningen, så du øjeblikkeligt ved, hvornår der er aktivitet. Reklamefri oplevelse • Ingen forstyrrende afbrydelser eller reklamer under dine paranormale sessioner.

Verdict
The clearest difference is ads: GhostBox at none against Fluid IQ test's shown. Fluid IQ test's advantage is device support (3 vs 1) and iOS requirement (15.3 vs 18.6). On price and in-app purchases there is nothing between them.
