You can solve daily one riddle of an IQ test. --------------------------------------------------------------- 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. --------------------------------------------------------------- Information about in-app purchases and subscriptions --------------------------------------------------------------- There is a Pro subscription in the app. The following notes apply: - The Pro Subscription offers you additional IQ Test functions such as explanations, further tests, numerous exercises and much more. - The Pro subscription is valid for 1 month and will be automatically extended for this period if you do not cancel 24 hours before the end of the period.

Il est difficile d’entrer 2 Chiffres dans les réponses car l’espace n’existe pas. Bref cette app est extrêmement décevante. ### 3/5 — Many errors *2026-06-07, version 14.6.4* I only recommend the free version of the app due to the number of errors. Sometimes there are wrong answers (especially on vocab Qs). But sometimes there’s a typo such as “answer for the question mark,” but there’s no question mark in the prompt… The app was clearly not made by a native English speaker, which is fine except where it interferes with accuracy, (which feels important for this kind of app) ### 1/5 — TOTAL SCAM BEWARE *2026-03-02, version 14.6.4* Do not download. We have been charged $30 a month with no ability to cancel. There is no customer support. ### 5/5 — Felipe *2026-02-11* App muito bom ### 1/5 — Scam *2026-01-16, version 14.6.1* They charge you without your authorization $29.99- DO NOT DOWNLOAD- YOUVE BEEN WARNED ### 1/5 — Subscription *2025-12-22, version 14.6.1* I used this app for about three days and bought premium to do whatever I wanted. I forgot about it and have been paying since. I can’t find anyway to cancel my subscription. I try on the app and it immediately send me to my apple Home Screen. Absolutely horrible. Would not recommend, please cancel my subscription. ### 1/5 — Errori *2025-12-06, version 14.6.1* Test pieno di errori ### 1/5 — Help *2025-12-06, version 14.6.1* Sorry its too low quality ### 4/5 — Not So Free *2025-11-08, version 14.6.1* My partner & I both sat together & tried the short quiz independently, comparing results. However, as we chose the non-pro option, we couldn’t see the answers/explanations without paying for pro, even with ads. This is disappointing as we couldn’t compare answers. As we’re not averse to ads, this would have gotten 5 stars if we could’ve seen our answers/explanations without paying. The few spelling mistakes weren’t bothersome as the app was created by a non-native English speaker, I believe. Well done with the app. Thoroughly enjoyable & shall recommend to other people. ### 1/5 — Click bait *2025-10-17, version 14.4.3* Don’t even bother. This is a scam. You’ll go through the entire test and then they ask for money to see the results. Standard scam. I fell for it. Obviously I’m not giving them a nickel because of the misleading nature of it. You should have to pay for this app upfront, not take the entire test and then have payment demanded. ## Frequently asked questions about IQ Test Brain Training Riddles ### What does the IQ Test Brain Training Riddles app do?
