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.
