Prime Factors

This is a beautiful, elegant, and useful app, one of my favorite math apps to use. I was very sad when it stopped working sometime last year, but now it’s been updated and it’s working again. I haven’t found another prime factorization app anywhere near as satisfying to use, so I’m very happy it’s back.

Edit: this app quite working a few months ago after ios18 updates. Still shows primes but doesn’t show factors of other numbers when you click on them. Really loved this app before. This app is perfect for me, I’m always jotting numbers down for patterns and god knows what. Big problem tho. It quite working after ios18 update. Please fix asap.

When I write in my journal, I check every day how many days old I am, and put the prime factors in my journal. This app is perfect for that.
