Great For All Ages/Levels


Brilliant is a wonderful app that promotes deeper understanding of both simple and complex subjects.

As a college STEM student, there isn't enough time to spend on fundamentally understanding every concept and learning the practical applications at the same time. Often, more emphasis is put on practical applications, which results in a lack of fundamental understanding later in life as I've experienced. Supplementing a STEM education with Brilliant has been an awesome experience and I always look forward to the weekly challenge problems!

Problem Solving with a Great Community

A Studious Student

Brilliant means “an inspired idea,” and that’s exactly what Brilliant is. The whole point of the app is to learn how to solve problems; using principles of science, math, and logic, you’ll be guided through lessons on all sorts of fascinating concepts. Grasp probability! Learn about the cosmos! Solve the weekly problem set!

Best of all, Brilliant has a community full of brilliant minds who will help you understand solutions and why they work. If an answer doesn’t make sense, discuss the solution and see why it’s true. You never know what you’re going to learn!

Promoting questions and deeper thought


This app does a great job at keeping your STEM thinking skills active. The questions of the day really challenge thoughts and the fact that there’s a community behind these gives it a more competitive yet friendly feel to it. The mini subjects that you can learn are also very engaging. I thought the premium membership price was too much but once I budgeted to pay for it I thanked myself later. Don’t sleep on this app if you want to keep exercising your mind!
