Last September, I have posted about MathCounts Trainer, a math competition app for iOS devices. In this post, I am going to introduce to you Brilliant, another math competition app which is both available in iOS and Android devices.
Brilliant is an app created by Brilliant.org intended to train users for problem solving, test preparation, and mathematics and science competitions. It has a wide range of problems in terms of difficulty ranging from basic concepts to Olympiad level. It includes problems in Basic Math, Algebra, Geometry, Calculus, SAT, JEE, Physics, Computer Science, and Quantitative Finance.
In Brilliant, you can select the subject that you want to learn and choose the topic or level you want to study. It contains thousands of problems created by a community of mathematicians and scientists. Users of this app can participate in discussions, follow other members, and learn from the community.
