Works Like the Original!

I just downloaded to iPhone 6S and had none of the resolution issues previously mentioned. This app works just as well as the original calculator. I believe the reviewers claiming a glitch skipped a set-and-forget step they did 20 years ago when following the books instructions - be sure to set p/y =12. After that, everything functions just fine. Love this! One less device to carry around.
