It’s useful

Prime is an incredible app if like me, you are interested in some really cool math games. You can choose any game to start up with and go through each one of them and explore all the amazing info and tricks the app provides. Its also really useful because if you need to find out not only if a number is prime, but also by what you could divide it by, the app will do just that in a clear and fun way! It totally think YOU should get the app because its useful, fun, and overall an app that will make you feel smart😉

Awesome app!

This is the app you were looking for. Clean, intuitive, precise. When you need a quick answer, google is too slow. Prime will give you all the info you need.
