HP calculator enthusiast – HP 15C Calculator Review

This is a superb emulation of the original Hewlett-Packard HP 15C calculator. I should know. I had an HP 15C when it was new. It took me through physics and calculus in college and the start of my engineering career. Regretfully a trip though the washer and dryer in the pocket of a jacket killed that calculator. I have bought and used other calculators but the 15C has always remained my favorite. When I saw this app, and it was made by Hewlett-Packard, I did not hesitate to purchase it. Reports the the app does not work with the latest iOS are out of date. Hewlett-Packard updated the app and it works flawlessly. As of this review I am using iOS 12.1.4.
