The best for me

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.

Great app! I use it every day!

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.

Beautiful app, but has stopped working

This was a beautiful, elegant, and useful app, one of my favorite math apps to use. But it stopped working a while ago. You can still scroll through all the numbers and see which are prime, but you can’t search for specific numbers any more and the app won’t give you the prime factors for any number any more. I hope this is updated before long! I haven’t found another prime factorization app anywhere near as satisfying to use.
