Brain AI has a 4.7-star rating on the Apple App Store and a 1.8 on Trustpilot. Both scores are real. They describe two different ways of paying for the same brain-training app, and one of them costs roughly 27 times more a year than the other.
If you found Brain AI through an online IQ test ad, paid $0.99 to see your score, and now see weekly charges of about $20.99, you’re in the group writing the one-star reviews. Brain AI is made by a real games publisher, so this isn’t a fake app. Our verdict on the web IQ-test trial is still Avoid: the pricing is steep, cancelling has been hard for many users, and the refund rules exclude exactly the charges people complain about.
Last checked: September 24, 2026. How we checked this is explained at the end.
Two storefronts, two very different bills
Brain AI is sold by Cleverside Ltd, a company registered in Limassol, Cyprus, which also publishes a long list of puzzle and hidden-object games on the App Store. Its terms name two partner companies as well: Cogvance Inc in Virginia and Codabrasoft LLC in Massachusetts. Charges can come from any of them.
You can pay in two places, and they barely resemble each other:
| App Store version | Web IQ test route | |
|---|---|---|
| Where it starts | Downloading the app | An IQ or ADHD test at a brainai.health address, usually from an ad |
| Listed or reported price | $7.99 a week or $39.99 a year (Apple listing) | $0.99 trial, then about $20.99 a week (user reports) |
| Who bills you | Apple | Brain AI’s own checkout, on your card or PayPal |
| Where you cancel | iPhone Settings | Brain AI’s cancellation bot or support email |
| Rating | 4.7 from 230 ratings | 1.8 on Trustpilot, 95% one-star |
Do the yearly math and the gap is stark. At $20.99 a week, the web plan comes to $1,091.48 a year. The App Store’s yearly plan is $39.99. Even the App Store’s weekly price works out to $415.48 a year, which is steep for a set of mini-games but still less than half the web rate.
That split also explains a complaint that confuses a lot of people. Web charges don’t appear in your Apple subscriptions list, because Apple isn’t billing them. One Trustpilot reviewer said exactly that: weekly charges kept arriving, and the app wasn’t listed under Apple subscriptions at all.
What the web checkout’s own code shows
The start of Brain AI’s web IQ test, where most of the billing complaints begin. Screenshot taken September 24, 2026.
We didn’t take the test, because the first step asks for your gender and later steps ask for your email. We did read the public code the page loads, which anyone can view in a browser. It holds the text of the paywall you see after the test, with the numbers left blank to be filled in: “Your {0}-day trial will cost only {1}. Afterwards, it will be {2}/week.”
Three details stood out. The code references at least five weekly plan versions and up to six monthly ones, and it picks the plan from the link you arrived on. So two people clicking two different ads may be shown different prices, which would explain why reports vary. The same paywall promises a reminder two days before the trial ends and a “30-Day Money-Back Guarantee.” And the page loads tracking pixels from TikTok, Meta, Google Ads and NewsBreak, which tells you where the traffic comes from.
None of that is illegal. Price testing and ad tracking are common. But when the price isn’t fixed, the only number that matters is the one printed on your own checkout screen, so screenshot it before you pay anything.
Where the complaints pile up
Brain AI’s Trustpilot page is small, with 21 reviews, so treat it as a pattern rather than proof. But it’s a consistent one. Reviewers report:
- two $0.99 charges during the “trial,” then $20.99 a week
- a 3-day trial with no obvious place to cancel, followed by three weekly $20.99 charges before support pointed them to a cancellation bot
- support saying it couldn’t find their account while charges continued
- a cancellation bot that showed a blank page or an error
- replacing a bank card as the only way to stop the charges
The company replies to nearly every complaint with the same short message asking people to email [email protected]. Older negative App Store reviews got a similar reply pointing to [email protected].
We checked the bot ourselves. When we opened the cancellation bot address listed in Brain AI’s help center on September 24, 2026, the page stayed blank and our browser logged repeated errors saying the chat widget hadn’t started. It may load for you, but don’t count on it being your only route out.
The refund rules don’t even agree with each other
Brain AI publishes two refund documents, and they give different windows. The terms and conditions offer a 14-day money-back guarantee on the first purchase. The separate subscription policy says 30 days, which matches the paywall.
Both documents exclude the same things, and they’re the things people actually complain about: renewal charges and “failure to cancel a subscription before renewal.” In other words, the guarantee covers the $0.99 trial and maybe the first weekly charge. It doesn’t cover week three.
The terms do include three clauses you can use:
- First-time users can get the trial fee back within 3 days of purchase.
- Refunds may be issued for “duplicate charges, incorrect billing amounts, or unauthorized transactions.”
- The policy says you must cancel at least 24 hours before a trial or billing period ends to avoid the next charge.
If you were charged after cancelling, that’s the “unauthorized transactions” clause, and it’s worth quoting back to support word for word.
How to cancel Brain AI, based on how you paid
Check your bank statement first. If the charge names Apple, you’re on the App Store version. If it names Brain AI, Cleverside, Cogvance or Codabrasoft, you paid on the web. These steps were checked on September 24, 2026, and companies change their flows, so screenshot each step as you go.
If you paid on the website (card or PayPal)
- Try the cancellation bot at iq.brainai.health/api/chat. Brain AI’s help article says you log in with your email and a confirmation code.
- Whether or not the bot works, email [email protected] from the address you signed up with. Say you’re cancelling, give the charge dates and amounts, and ask for written confirmation.
- If you were charged after cancelling, or twice for the trial, ask for a refund under the billing errors clause in the terms.
- If charges keep coming, call your bank or card issuer, dispute them with your screenshots and emails, and ask whether a replacement card is needed to block future attempts. If you paid with PayPal, you can also stop the payment from PayPal’s automatic payments settings.
If you subscribed in the iPhone app
- Open Settings and tap your name.
- Tap Subscriptions, then select Brain AI.
- Tap Cancel Subscription. For a refund, request it from Apple at reportaproblem.apple.com.
If you subscribed on Android
Open the Google Play Store, tap your profile icon, then Payments & subscriptions, then Subscriptions, and cancel Brain AI there. Deleting the app doesn’t cancel anything, on any platform. Brain AI’s own policy says so in bold.
What you actually get
The app itself is a bundle of 30-plus short games in memory, logic, math and problem solving, with a daily plan and some personality and IQ-style tests. Some reviewers like it. The one recent four-star Trustpilot review said the games got repetitive.
Brain AI’s terms are unusually blunt about the limits. They say the IQ scores aren’t clinical assessments, no clinical trials have been run on the training programs, and there’s no guarantee of any cognitive improvement. The same goes for the ADHD quiz on its website: it’s an online questionnaire, not a diagnosis. If attention problems are affecting your life, a doctor or psychologist is the right place to start.
On privacy, the App Store listing says data such as purchases, coarse location, identifiers and usage data may be used to track you across other companies’ apps and websites. That’s common in free-to-play games, but it’s worth knowing before you hand over an email address.
If you still want to try it
Skip the web IQ test and download the app directly, so Apple or Google handles billing and cancellation. Pick the yearly plan if you’re committing, or don’t subscribe at all. It’s the same trial-to-subscription pattern we flagged with Finestro AI and Use.AI’s $1 trial, just with a weekly clock instead of a monthly one. And it’s the same weekly-billing trap behind the AI Cleaner complaints.
Weekly billing is the part to watch. A charge that looks small every seven days adds up faster than a monthly one, and it gives you less time to notice.
How we checked this
On September 24, 2026 we read Brain AI’s terms, subscription policy and cancellation help article, its App Store listing and its Trustpilot page. We opened the start of the web IQ test and read the public code it loads, and we opened the cancellation bot page listed in the help center. The screenshot above was captured that day.
We didn’t take the test, enter an email, start a trial or pay, so we couldn’t see the exact price shown at checkout. The $0.99 trial and $20.99 weekly figures come from customer reports; the App Store prices come from Apple’s listing.

FAQs
Is Brain AI app a scam?
It’s a real app from Cleverside Ltd, a Cyprus-based games publisher, not a fake. But its web IQ-test trial has a pattern of weekly charges and hard cancellations, so we rate that route Avoid.
Why is Brain AI charging me $20.99 a week?
Most likely you paid a small fee to see an IQ test result on the web, which started a trial that converted into a weekly subscription. Web charges are billed by Brain AI directly, so they won’t show in your Apple subscriptions.
How do I cancel my Brain AI subscription?
For web purchases, use the cancellation bot at iq.brainai.health/api/chat and email [email protected] asking for written confirmation. For App Store purchases, cancel in iPhone Settings under your name, then Subscriptions.
Can I get a refund from Brain AI?
The policies offer a refund on the first purchase within 14 or 30 days, depending on which document you read, but exclude renewals. Charges after cancellation or duplicate charges fall under the billing errors clause, so cite it when you ask.
What is BRAIN AI APP on my bank statement?
It’s almost certainly a charge from the Brain AI brain-training app, often a web subscription started through an online IQ or ADHD test. Charges may also appear under Cleverside, Cogvance or Codabrasoft, the companies named in its terms.
Is the Brain AI ADHD test accurate?
Brain AI’s own terms say its tests aren’t clinical assessments. An online questionnaire can’t diagnose ADHD, so speak to a doctor or psychologist if you’re concerned.
