CerebrumIQ, Yourselfirst and CogniFit  –  a review of three ways to test your mind online

User reviews of CerebrumIQ, Yourselfirst and CogniFit show how differently IQ, self-reflection and brain training feel in practice

The appeal of online cognitive tests is easy to understand. A few minutes of focus, a screen full of shapes or statements, and a score that tells you something – about your intelligence, your personality, maybe even your future. But while the promise is universal, the experience can be wildly different depending on which platform you choose.

Some platforms feel clinical. Others feel like pop psychology dressed up with gamification. And others? They seem to leave users wondering whether the result was worth the price – and whether they agreed to pay it at all.

Three platforms come up often in this space: CerebrumIQ.com, Yourselfirst.com, and CogniFit.com. Each presents a different angle: IQ measurement, personality insight, and brain training. But what users say in their reviews reveals what really happens once you click “start.”

CerebrumIQ.com gets the basics right, with a few common caveats

Among the trio, CerebrumIQ seems the most straightforward. The platform offers a 30-question IQ test that evaluates logic, memory, and pattern recognition. After finishing, users receive an IQ score, a downloadable certificate, and a brief breakdown of how they performed.

The tone across reviews is calm. On Reviews.io, the platform has more than 1,000 user reviews with an average of 4.6 out of 5 stars. Many users describe the test as easy to navigate and reasonably well-structured. Some mention they weren’t expecting the result to feel “serious,” but were pleasantly surprised.

That said, not every review is glowing. A handful of users mention they assumed the test was free, only to learn later that it leads into a paid subscription. The trial period is clearly outlined on the site, but – as is often the case online – it’s not always the first thing users notice. The setup: a 7-day trial, which converts into a recurring plan unless canceled manually.

Unlike more aggressive platforms, CerebrumIQ doesn’t push upsells mid-test or hide your score behind a last-minute paywall. But reviews make it clear: you need to read the terms. Still, it’s telling that most negative reviews center around billing – not around the test content itself.

And that content? Users generally describe it as reasonable, engaging, and worth the time. Not revolutionary, but not empty either. For a platform that promises a basic cognitive snapshot, that’s a decent outcome.

Yourselfirst aims for introspection  –  but runs into trust issues

The tone shifts when you move to Yourselfirst, a platform that markets itself as a tool for personality insight and self-awareness. The branding leans into calm colors, therapeutic language, and phrases like “see yourself as you really are.” The idea is to align self-perception with reality – a compelling offer, especially in the age of self-optimization.

But a scroll through user reviews shows something else: frustration, confusion, and a lot of refund requests.

On Sitejabber, Yourselfirst holds a rating of just 1.5 out of 5 based on over 240 reviews. Many users say they found the test slow and repetitive. Others were less concerned with the test itself and more focused on what came after. In particular, a large number of reviews describe unexpected monthly charges.

One user wrote: “I thought I was just taking a long personality quiz. Paid to see the results, and then started getting billed $30 a month. No reminder, no confirmation. Just charges.” That sentiment appears again and again – across Sitejabber, app reviews, and even the Google Play Help Community, where users report similar subscription confusion.

To the platform’s credit, some users describe the insights as “interesting” or “thought-provoking.” But these comments are typically buried beneath concerns about billing transparency. The platform uses a trial model similar to others in the industry – a low-cost initial payment, followed by auto-renewal. But what sets Yourselfirst apart, according to users, is how little warning they felt they received.

The end result? Even those who liked the personality analysis often say they wouldn’t recommend the experience. And for a site built on self-clarity, that kind of user reaction carries weight.

CogniFit offers more structure  –  but it depends what you’re looking for

Unlike CerebrumIQ and Yourselfirst, CogniFit doesn’t try to diagnose or define you. Instead, it positions itself as a cognitive training system – a combination of digital games, personalized challenges, and progress tracking designed to help you improve mental agility over time.

The platform includes a set of initial assessments that evaluate attention, memory, reasoning, and more. Based on those results, users receive a custom training plan. CogniFit claims to use science-backed methodologies and has partnered in the past with institutions involved in cognitive research.

The reviews, though, are mixed. On the App Store, some users praise the variety of games and the adaptive difficulty. Others report technical issues, such as glitches during exercises or confusing interfaces. One reviewer wrote: “I like the idea of the app, but several of the games have overlapping graphics that make them hard to use. For something that’s supposed to improve my attention, it really tested my patience.”

There’s also the matter of pricing. CogniFit offers a subscription plan, and while the terms are clearer than those on other platforms, some users feel the monthly cost is high for what they get. According to a MindTools.io review, the app works well for some audiences – particularly older adults or people interested in daily mental routines – but may feel underwhelming for users expecting deep feedback or advanced tracking tools.

Still, for those looking to add light cognitive training to their day, CogniFit isn’t trying to be something it’s not. It’s not a clinical IQ test. It’s not a psychological profile. It’s a brain-fitness app with a moderate learning curve and a subscription fee that you’ll want to read before clicking through.

What happens during the test is important. What happens after often matters more.

That’s the recurring theme across these platforms. People don’t just review the test content. They review how it made them feel, whether they got what they expected, and whether the experience respected their time and attention.

CerebrumIQ seems to earn the quietest satisfaction. It’s not full of bells and whistles, but it doesn’t pretend to be. Most users come out with what they signed up for, or close enough.

Yourselfirst, despite its introspective pitch, leaves too many users frustrated by unclear pricing and underwhelming delivery. Even users who liked the personality feedback say they can’t recommend the process.

CogniFit carves out a niche in cognitive training. The value depends on what you’re hoping for. If you want measurable improvement in attention or memory, and don’t mind a few interface issues, it might work. If you’re expecting a fully immersive diagnostic tool, you may be disappointed.

The common thread? None of these platforms are inherently “scams.” But they do require attention. The score or result you’re given may be interesting, but it’s only as useful as the clarity of the process that gave it to you.
