By freeze I mean that the little sand dial on the battery comes up and just remains stuck there. I then have to shut the app up entirely.

I also find that my iPhone 5s gets very hot randomly when using the Prime app. Not sure how to reproduce it. But it gets as hot as when I am watching a Netflix movie.

Thanks Again.

I have noticed the same conditions as Luis mentioned on my iPhone 6+. It seems that the processor is working very hard to handle Prime calculations, hence the heat. I also had a 'freeze' but under different circumstances: while doing a matrix inversion (100x100) the iPhone went into auto-lock and would not respond to touch at all. I had to do a warm reset. I'm a registered iOS developer, and by no means an expert, but it looks like the Prime is not playing nicely in the iOS.

BTW, the matrix inversion worked and completed on a subsequent try. The plastic Prime balks at anything over 50x50 and the iOS is much faster. Maybe too fast . . .. Some control might be given to the user in 'Settings' as is the case with other calculator ports?
