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.

This app is really good! I love how far up it can go. It can go up to over 100 Billion!
