Complex RPN Calculator is free iOS app published by John Coddington
Marvelous - solves sad fact of consumer rejection of RPN

...but it has stopped working in latest iOS! We have no right to expect updates to freeware, but we can hope and pray for what we don't deserve.
Get the PRO version

Coddington has a PRO version of his RPN calculator app that works fine on iOS 9. It does not show both of the functions at the same time for keys that do double duty like the regular version did (for example X squared and square root of X), but at least it doesn't crash and doesn't have the annoying upside down "feature". For the second function keys, just type the 2nd key in the bottom left corner, and the entire keyboard now shows them. Hope the developer updates the app to adjust the PRO version to look more like the regular version keyboard, as the Pro keyboard has an odd look to it.
