Description
Are you a Prime Number enthusiast? If so, this app is for you, with its simple yet powerful function: Given any integer, determine primality or all prime factors.
The Primality App has a clean and simple, yet powerful, function: Given any integer, the app determines either that the given integer is prime or else it provides all prime factors of that integer. Very clean, very simple, focussed.
The app operates in the range of 0 - 999,999,999,999.
A popular feature of the app is its ability to determine the prime ordinality of each prime found, such as observing that 97 if the 25th prime. (However, this particular feature is available only up to the 100,000th prime, which is 1,299,709.)
Requires iOS 13 or higher.

Ratings and Reviews
Fulfills your prime number curiosity
This is a great app with a streamlined interface to answer the question that comes up surprisingly often in random conversation: is this number a prime? Nice features to answer that question and show the factors if it’s not prime, or tell you which n-th prime number it is. I see a fun car game with the kids in the future!
Let’s gamify it!
Very cool to test your mathematical recall skills. Would love some “game modes” that give you some numbers inside of bubbles or balloons an you have to pop the ones with prime numbers. Accelerate speed as you progress. Maybe a quiz mode that starts at a random number and you have a time limit for entering the next five prime numbers in order. Difficulty could be determined based on how large a number you start with.
Super fast factoring of numbers
Are you one of the numerical geeky sorts who likes primes? This is a fun tool to show you the factors of a number or whether it’s a prime number. Can’t say it’s useful but it’s a clean interface, simple and fun to check even really large numbers.
