Regarding Prime cracker v2.4

This is a wonderful app for quickly finding out whether or not a given number is prime. I like how it even gives you all the possible factors of the number itself. I would highly recommend this app to anybody interested in learning about different types of numbers: Composite, Prime, etc.

Holy Molie!

Incredible primes explorer. Ultra fast, flexible, user friendly and the best prime number tool in the world for what it does and I’ve checked a lot of apps out.

Ranges, enumeration, twins, validation check, what’s not to like! THANK YOU genius programmers, and as far as I can tell free full version

A life changing app!

I used to spend way too much time cracking prime numbers manually. But then I found Prime Cracker! Thank you for giving me my life back, Prime Cracker!!!
