I had the same experience as other 1 star reviewers here. The free trial is like a trap. If £100 makes a difference to you, don't touch it.

When first time i saw this app on play store i was shocked. The idea behind it was magnificent. But I doubt that they can make it real, spoiler alert: they did.

The topics are Brilliant, and wide. From it to art to mathematics.

I'm from Iran. A country in middle eats. Unlike they're politicians Iranian are kind, happy and funny. In January, regim kills around 10000 Iranian protests. They shut down Internet and kill their people.

It's a very dark and terrifying era in my whole 5000 years of Iran history. But one thing make me feel better. Brilliant was helping us. They didn't broke our strike chain . Even this little help was alot.

Thank you Brilliant. Thank you Steph(the admin)

I think Brilliant is decent, but not outstanding.
I’ve tried it, and it’s especially strong for mathematics.
However, if you want to improve your programming skills (for example in Python), it’s smarter to learn with the help of AI and to experiment using online coding compilers.
This way, you can learn for free and at least ten times faster, which simply makes more sense.
I also believe Brilliant could benefit from offering more dedicated courses in science and engineering, such as civil engineering, energy systems, chemistry, optics & photonics, and mechanics. Some of these topics are touched on in the Scientific Thinking course, but in my opinion, they deserve full courses of their own.

If I could give 1/2 star that would be awesome. This company is a total rip off. They charged me for something I never purchased. I have no account with Brilliant and they won't refund me unless I sign on to my account. Of course, yet again I do not have an account with Brilliant. Customer service on refunds deserve a ZERO!!!!!!

Really liked the sample but asking for your payment information before the "trial" period seemed like a test of your intelligence in itself.

It's too bad because I was pretty likely to have subscribed it it hadn't been for that.

Quick and helpful response.

They never recall about my trial ending and the renewal. THEY TOOK 120€ (150$) without any previous notice and despite me trying to cancel the renewal literally 20 MINUTES after they took my money, there no way to get a refund on the website. You have to harass them, that's the way they ask to be treated!!!!
And their service is really bad, it's nothing special, just some ridiculous graphical animation, the same as in a study book but on a website.
Don't get scammed like me!!!!!!!!!!!!!!!

Will charge you even after subscription is cancelled during "free" trial of premium. No reply to emails. Stay away from this company!

Agreeing with other reviews here that there are issues with billing. We didn't notice the renewal because it was sent to my daughter and even though we hadn't used the account they would not offer even a partial refund, helpfully pointing out (as they have to other's here) that all payments are final - watch out!

The content itself was so-so, but it never really captured the imagination of the kids. There are better and cheaper routes to learning math available.

Great learning app that’s easy to use however I didn’t want it long term. I forgot to cancel and, despite their terms, they issued me a refund out of goodwill. Great customer services.

I had a problem getting my account activated. I reached out to the support team through email, and got a message from Sandy. She was very helpful and got the issue resolved quickly!

Thanks Sandy, I love the brilliant app. Soo well presented. As someone with ADHD, I’ve so struggled to get my head around so many concepts. Now I can take advantage of so many avenues that have been closed off. 
Thank you so much! 

I gifted a premium subscription to a friend who enjoys gaming, so I thought he could benefit from Brilliant Farming.

Right now I'm at the time of learning

Be careful signing up to Brilliant. They will make large unauthorised debits after you've cancelled the subscription and will refuse to refund the money.

In response to Brilliant, that is simply not true. I cancelled the subsription but was then was charged $171.6 USD. I suggest you review your company ethics and practices because going off my experience and judging by the feedback of several other customers the issue is ubiquitous.

Reply to Brilliant: let me clarify for you, I cancelled the subcription during the free trial period in May 2025. (Had I known this would happen I would have taken a screenshot as proof but I was naive). Then I was charged in June 2025 without my knowledge, which I only became aware of recently while filing taxes, Disgraceful and unethical! This matter could easily have been resolved with a full refund and apology, but instead Brilliant doubled down and gas lit. Keep the money! You will never get my business again. I hope prospective customers read this before supplying their payment details to this unscrupulous company!

I have already dealt with the (not so) Brilliant support team. The support team may as well be robots. They don't read or address customer complaints and respond with cookie cutters. I raised this issue with two staff members, neither appeared to have read my complaint, nor address my issue. Anyhow, i have raised the issue with my bank because i have gotten no where dealing with brilliant.

Also i did not "accept any trial extentions" as suggested. That is untrue.

Ridiculously hiding the price of the premium package even though they keep forcing it upon you. They keep advertising 30 days free trial and 20% discount on every step but not showing the actual price. Even when you get to the point of entering card details you still have to unhide the "details" to finally see how much they want to charge you. It all has a feel of a scam. I know it's not and it generally gets good reviews, and it's not actually a scam site, but if you've got good content you shouldn't be trying to hide the charges in such a scammy way. It just puts you off completely regardless of how decent the content may be. They won't see me back any time soon. Just can't trust them.

Helpful Support and good Visual-App-Design!

Awful company. Emailed support within a few hrs of money leaving account explaining I did not want the subscription and was struggling to figure out how to cancel purchase. There is a right to cancel a subscription usually within 2 weeks, I emailed a few hours after payment was taken and they are charging the full annual fee, absolute rip off company

they are disgusting greedy people, do not suscribe, is basic stuff and they charge you without asking for basic level knowledge

Signed up for an account to see what it's like and my inbox was flooded with emails daily. On top of that because I'd used social login the delete account wasn't intuitive at all.

Because I'd use social login didn't have a password set, however, you need to enter a password in order to delete your account. This summer waffle about being able to set a password in your social connection page whatever that is. However, it also told me that I wasn't connected to Google.

In the end, I managed to delete my account by putting a space in the password field. I didn't expect that this would work.

In the best case scenario, this is just poor Ux design, in the worse case an element of dark Ux was employed to make the account removal process unintuitive.

Brilliant have responded, let's see if they are comitted to solving the problem. What happens next will be quite telling.
