Nothing about the site made me feel safe. It all felt off. After everything, I just feel misled and regret even trying it - not worth the stress or time invested.
No clarity until it's too late. I felt tricked. The whole setup feels intentionally misleading, as if it's made to trap users rather than help them with real results.
I got billed and never even got an invoice. Feedback on that. The lack of any warning or proper explanation made the situation worse.
My experience: gave details once, and they used them multiple times. The lack of any warning or proper explanation made the situation worse and I couldn't get reliable support afterward.
I couldn't find a way to delete my info. Review on that issue. And the worst part is, I still haven't received a proper confirmation or follow-up message since the issue started.
You didn't know what you're agreeing to. Feedback - intentionally vague. The lack of any warning or proper explanation made the situation worse, and I couldn't get reliable support afterward.
Report was one paragraph. That's not value. That's disappointment. The lack of any warning or proper explanation made the situation worse, and I couldn't get reliable support afterward.
Click cancel, nothing changes. Then you're billed again. It's disappointing that something so simple turned into a confusing and frustrating ordeal with zero accountability.
Unpolished, half-baked, and unreliable. My experience was full of doubt. After everything, I just feel mislead and regret even trying it - not worth the stress or time invested.
I saw charges without ever agreeing to anything recurring. I tried multiple times to solve it myself but ended up going in circles with no result and growing concern. Can't remember to having such a bad experience with online services.
I didn't sign up for a subscription. Yet, every month, another charge came through. They don't notify you. They don't warn you. They just quietly drain your account. I had to cancel my card just to stop it. Inexcusable.
This is what I get for not reading the fine print. They charged me without permission and would only refund part.
The test feedback looked like it was written by a robot—completely impersonal and irrelevant to my actual answers. For something that costs money, I expected at least a hint of personalization. What a joke. It's all polish and no substance.
I signed up for IQ Brain expecting something fun and educational. Instead, I got a cheap-feeling quiz, vague results, and an unexpected charge on my bank account. Nothing about the experience justifies the price. It's misleading at best, a scam at worst.
I scoured the entire website looking for a cancellation button. It's either buried or nonexistent. Meanwhile, they kept charging me monthly. It's beyond frustrating. I had to contact my bank to block future payments. What kind of business operates with this level of sneakiness?
What starts as a harmless little IQ quiz quickly turns into a shady subscription trap. No upfront cost is mentioned, but as soon as you hit "submit," you're asked for payment. It's dishonest and exploitative. I expected better in 2025, but apparently some tricks never go out of style.
There was nothing special about the quiz. It could've been made by a high schooler. But the charges? Very real. If they spent half as much effort on their product as they did on tricking people, maybe this wouldn't be such a scam.
From the vague terms of service to the unclear billing policies, this site screams scam. I shouldn't have to chase down a company to cancel a subscription I didn't knowingly sign up for. Their entire model relies on confusion.
If I could go back, I'd never have clicked that ad. It seemed like harmless fun, but I ended up with charges I didn't agree to. I don't care how smart the test says I am—it took real stupidity to trust this company.
I didn't even realize I was subscribed until I saw the second charge from IQ Brain on my account. There were no reminders, no invoices, nothing. Just quiet billing in the background while you forget you ever used the site. Unacceptable.
