Complex RPN Calculator is free iOS app published by John Coddington
Broken in iOS 9.0.2
On my iPad model 770LL/A running iOS 9.0.2, the app crashes upon a button push. Downloaded again and got the same result. Love the app, but unfortunately it no longer works, at least for me.

I used this app almost every day as liked the rpn format. However with recent IOS changes it crashes on any key stroke. Guess will have to find another one.

Under iOS 9.1 (the only version I’ve tried this with), the app crashes instantly when I press any function, including ENTER.

Crashes on opening. I used to use this instead of my HP 32sII. Now I have to carry it around. John, please fix this.

The calculator no longer works. Is there a fix coming? Or can I get my money back?

Please, John. This is a 'must have' app for many of us. Now with IOS 9, it is non-functional. We NEED the update. Thanks.

Doesn’t work in iOS9, however it used to work well. The same developer has a newer app which is similar and does work in iOS9, so I recommend switching to that app.
