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!

Good App

Clean and quick, instant results. Primes and Factors.

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.

Found a five digit prime number

Nice program to determine if a number is prime. I’m waiting for the vision addition where I take a picture of the number and it indicates prime or not prime.

Best prime number app I’ve ever used

👍👍!!! Definitely worth the price

Very clean app, with great usability and performance.

The UI for this prime number app is completely intuitive, and set up to allow easy exploration of the region of any number. The performance is startlingly good.

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.

We really enjoyed this app BUT

My wife likes it BUT thinks it should produce fireworks if the user finds any prime numbers of at least 5 digits!
