Perfect app and great support team This is indeed great app and great people who support it. I think it is hard these smartphone days and distractions all over to focus and study, although it is so interesting stuff to learn. I wish I had the time and learning skills to use it properly. Last thing to note the subscription model, where you automatically paying w/o noticing should be changed. The company must try to find a way to inform customers before auto renewl period

Great interactive learning tool Great interactive learning tool, works like duolingo but for maths!

Navigating App Usage and Subscription Refunds: My Experience The app works smoothly and taught me some basic coding skills that I was interested in. However, I'm unsure about its depth. I decided not to continue the subscription because I stopped using it after two weeks. Unfortunately, I missed the cancellation deadline by one day. Initially, they were reluctant to refund me, but after expressing my dissatisfaction and threatening to leave negative feedback across various platforms, they refunded 11 out of the 12 months. Overall, the customer service was very friendly and effectively resolved the issue.

Disappearing classes Although the classes are interesting and the math is (sometimes) well explained, there are also a lot of issues with Brilliant: *Classes disappearing in the middle of doing it. Algebra 2 for example *Classes skimming through essential piece of information, e.g. Introduction to linear Algebra. I'd really recommend a mix of other solutions if you want to further your understanding of mathematics. Khan Academy & 3Brown1Blue (and many other free resources) provide better explanation and have the same level of interactivity.

Customer Support Just want to say that in these days of AI/Automation, it was extremely pleasant to get real, prompt and excellent customer support. Maria responded right away and took care of the matter right away! Awesome!
