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.

I would rather pay to see no ads

The app works, but the ads are very, very annoying. It’s a combination of outside ads and ads for the developers own apps. I would rather pay for the app than see the ads. If I didn’t have to see the ads, I would rate this app four or five stars. I am deleting this app, I can’t handle the ads.
