Complex RPN Calculator is free iOS app published by John Coddington
G.R.W.
The web site claims that from version 2.6 the program finally "includes complex numbers". This is totally misleading! It only does a couple of very rudimentary operations with complex numbers, and is UNUSABLE for any real engineering or scientific calculations with complex numbers. I am disgusted that I had to pay to find this out. It is so misleading that Apple should pull the app until the author stops claiming features that are just not there. If you need complex numbers, do not buy this. --George

Great app, but with IOS8, if you like having your iPad oriented with the home screen to your right, the app starts up upside down. The only way to correct it is to tilt to portrait then back to landscape. Wish they would fix this.mgoing yo have to find a different RPN calculator unfortunately.

Other than syntax being just slightly different than an HP, this is functionally identical and works great. I love it--thanks for a great app!

I was very happy with this app. It was my goto calculator. But now it's gone. Just refuses to start up under ios9 on my iPhone 6.

Used to work great. No longer works on iPhone 6 with ios 9. iOS 9 problem or cmpxRPN problem. Doesn't work.

This used to be an awesome calculator for those that use RPN calculators. However, it fails to load up after the iOS9 update.

For years this has been my go to calculator. I use it interchangeably with my real HP scientific calculator. It's been flawless. Until now. With iOS 9 it just refuses to run. Please update it.

Loved it until that moment. It needs an update. Get cracking, developer.

Great app. BUT it no longer works after I updated to IOS 9.0 today. Would be great if it could be patched to work.
