希望增加位数，完善因式分解功能。

### 5/5 — Does exactly what I needed!

*2017-04-03*

Thank you, it's precisely what I needed for the project I'm working on.

Would be nice to be able to buy the adverts away. 

Would also be nice to see a more visual display. Perhaps a slideable number line. 

I'm not using it for heavy duty maths or coding, just to explore for a short film.  

All the best.

**Developer response:** Hi James, thank you very much for your review! You are right! There should be an adverts free version, in fact this app ought to be adverts free, which is why I have already released a version that is free and ads-free and it will remain so in the future.
As for your other two proposals, a more visual display and slideable number line, to discover prime numbers in another way is interesting, however not in my plans at current.

### 5/5 — Love it

*2014-06-15*

It's a simple but effective app. Helps me with my child home work.

### 5/5 — Clean and simple

*2014-05-26*

Does numbers up to 2^64.
Has nice extras like next prime and primes in a range. Easy to use. Simple useful output. Needs a previous prime function.  Great app that gets the job done
