Good

Love this app!
I got this app years ago and I have never had a problem with it. I am surprised there aren’t more users. I teach math and have used it more than once for really large numbers.
Seems broken

Yay!
So happy to see an update to this handy little app. Helping my kids with math homework has been way easier since I downloaded it years ago. Thanks!
Wha?
I enter a number, it ignores it and tells me another number is prime. Useless.
I Love It!
I have a little obsession with prime numbers, so this app is great fun for me. Back in high school (in 1975) I was in the first computer programming class in the LAUSD. I wrote a little program to give me a list of prime numbers. The program would be run, at night, on the school districts IBM 360, and took forever (many minutes) just to calculate a number as small 103. This app handles much much larger numbers with ease, in fractions of a second. I love it!

Great
Great app! My only complaint is that when a number is composite, the app doesn't give you its prime factorization. For example, it'll say 12 = 2*6 instead of 12 = 2*2*3
Works good
Very awesome I needed it for homework and it helped me!!! 5Stars!!!
Good
It would be awesome if it could tell u its factors to
This app is worth it!
This app shows how such a simple app can serve such an important purpose in your life. I rarely give out 5 star ratings but this app had simplicity and also acts as a math guide. Saying that I think this app is creative and worth the extra space on your iPhone/ iPod touch I also think that This app will be helpful to many people. This app is very enjoyable but sadly I would not pay $0.99 for this easy, creative, helpful application.
I hope this review helps all,
