i love this app
I purchased this HP 15C calculator app becauee I've used the original HP 11C, since 26th September 1986. It is fun to use on my iPad.
United StatesHP 11c Calculator
Best scientific and engineering calculator ever made.
United Statesvery happy to get a New HP11c !
My 1981 is still working like new, but sure doesn’t look it. This app makes my iPhone and iPadmini just as good as the real thing. For several weeks I did all kinds of stuff on it to see if it had any flaws/errors. Zero !!! and I love it as much as my original. One minor annoyance; when I hit prefix to see all digits, it just flashes the digits too fast for me to read. My old HP showed it as long as I held the button. But still a 5+++ Thanks for the exceptional re-creation.
United StatesJust downloaded app. So far, so good.
I still have, and occasionally use, the HP11C I bought in 1986. I’m very glad to have this app on my iPhone 12 with iOS 16.1.1. The “click” on every keystroke is a good substitute for the old HP11C “feel”.
United StatesI Like It
I purchased my first 11C probably around 1976 or so on the recommendation of my engineering student brother who explained the advantages of RPN to me. The transition was easy since I was not a calculator user prior to its acquisition. I have three now, one at home, work, and on my boat. I have been a machinist for 35 years so the one at work sees the lions share of use. I am absolutely thrilled to now have it on my phone so I have instant access to it 24/7 regardless of my location. The majority of my use is simple number crunching and trig functions so I could not be considered a power user or expert on it but I am absolutely happy and satisfied with this app on my phone. Now when at work if I am standing in front of a machine tool and want to add or subtract two numbers I whip out my phone rather than walk the 30 or 40 feet to my office and back. I am highly protective of my beloved 11C so it rarely makes an appearance on the shop floor for fear of being damaged or destroyed.
