The spirit of Corvallis lives here

The excellent attention to detail, human engineering and relentless debugging makes me feel like I'm dealing with the wizards of HP when calculator development was at its highest art. I wish the developer would create an HP67 emulator, too. Well, I can wish :-). Great program and worth every penny!!! I've been using it for some time and have not found any problems. It is like having my old '41 back, ONLY BETTER.
My main iPhone calculator for years

The 41CX carried me through college back in the 80's. I was ecstatic to see the iPhone app. I've been using the app for years now and am very pleased. Not only is it great to have the full features (and then some) of the original 41 series, but having the option of the distinctive audible feedback on each keystroke is INVALUABLE in that it provides assurance that your keystrokes are executed properly (since there is no tactile feedback of true buttons as their is on the original 41 hardware). You can hear (and feel) the audible in this app. Full featured and reliable. Great job!
Ol' Trusty lives

OUTRAGEOUS! I've used my 41C since '83 and don't want to relearn what's now instinct. With this app, I don't have to. I still have Ol' Trusty with me everywhere I bring my phone. Ive started a new job and only use the app. It works exactly like the real thing, but includes SO MUCH MORE! Great thing is, because I bought it for my iPhone it has automatically loaded on my iPad. Thanks. It was worth every penny.
RPN Calculator.

I was the fifth person at Kansas State University to have an HP 35 in 1972. Serial Number was less than 5,000. Only one in Engineering Department. Took them a couple years to figure out the advantage I had over a slide rule. Pretty great app. Joe
Best and Most Used App on my Phone

Used daily for several years now, this application is constantly being updated by the developer. Outstanding support, meticulous emulation and excellent graphics (probably the best available for a vintage HP calculator); a fine example of what an app can and should do on this platform. Too many positives to list, one nit for future coding: add tactile key feedback option using vibrator hardware. Thanks to everybody that stays up late polishing this beauty!
Just like my HP-41CV

My HP-41CV was a crucial tool in my undergraduate Aerospace Engineering degree program. This app replicates that hardware perfectly. Great app.
What a calculator!

Back in the eighties I used the original HP-41c and its descendants for technical work on contract for the USAF, so having this program is a dream come true. The original was astoundingly good; this is even better -- smaller, faster, more memory modules, much less expensive, etc. if you do not already know reverse Polish notation, which the calculator uses, you will have a short learning period, then all will be MUCH faster than with a standard algebraic calculator. The 41C is almost addictive -- I cannot imagine using any other calculator now. Recommended w/o the slightest reservation!
