Prefacto - Prime Numbers

A powerful, fast, prime numbers galore app

Throughout the day, I’ll occasionally find myself wondering, “Is that number prime? If not, what are its factors? How far is it from other nearby primes?” If that sounds like you, then look no further – this is the app for you!

This is the PRIMEir app for prime numbers and is very fun. It's cool to look to see who's birthdays are on prime dates or not. Overall one of if not the best niche apps ever.👍👍👍👍👍

I’m not sure exactly why being able to calculate primes on the go is necessary; but somehow it’s empowering. It scratches the same itch as the star tracking app. Thanks guys. Really love it.

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.

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😉
