Best calclator app

robertmtech

I can't say enough about this app. I've used it for a long time, and it is a completely accurate and functional 41C on your iPhone/iPad, as well as a full fledged (integrated) CAS. The developer is constantly fixing and updating, and is reachable. It may seem expensive, but for what you get, it is well worth it. I use this as my everyday goto calculator, as well as for "fun" with programming.


The best

Megadolomedes

I have tried probably a dozen calculators, this is the one I use, the "buttons" on this one produce less data entry errors for me.


Awesome app, great updates

Excellent RPN calc, tons of options, and the dev keeps it updated.

This is the best app I have on my IPhone. The HP41cv was the best calculator ever made and I still have mine and it functions. But this gives me access all the time to it. It only they offered the various application packs as add ons! If you want to still have an HP41cv then get this app.


The best HP41CX available.

The i41CX+ is a FANTASTIC HP41CX emulator, complete with 'plug in' modules and 'keyboard overlays'. I own four original HP41 calculators and a fair number of modules - but even the most reliable of these 30+ year-old electronic devices occasionally 'crashes' and loses data/programs. This app allows the user to avoid the frustration of malfunctions, while still enjoying the versatility of this ( relatively ) powerful, and ( definitely ) historic, computing device. Sure, even the cheapest, weakest, PC available today can do WAY more than a HP41CX can do, and do it much more quickly. But these old calculators required you to really use your brain to plan out programs utilizing limited memory and program steps. Sometimes I have fun trying to think of new ways to solve problems within the calculator's limitations - I also like the notion that I'm using the same device NASA chose as the back-up for the Space Shuttle's computer navigation system. I just wish the App Store had charged me the 'upgrade' price, instead of the full purchase price, since I previously shelled out $7.99 for the basic i41CX app. I'm not sure what went wrong in the purchase process, but I was definitely overcharged. So, five stars for the great calculator app; and, at most two stars for customer service.


Perfect

Lucky_in_Life

This app is just as great as the HP 41CV, which I still have. Have been using the app since it became available.


Fix it finally

Eugene Hulbert

The most updated app on iTunes. That's not a compliment, it a measure of incompetence. Fix it and get it over with, please.


Excellent app and support

MrACME

App is very accurate on iPhone and iPad. Wish I had the same app on Mac OS, and Win7 (use other emulators on those that aren't as good). Use it every day for engineering calculations. Support is good.


Excellent Emulator/App

Nav User 2012

Outstanding and amazing HP41CX emulator. Works better than the original calculator - I still own two of them. True, lots of updates, but the guy is adding interface features to the iOS system. It's NOT a sign of incompetence or whatever that clown below posted.


By far the most sophisticated calculator for iOS

Unlike many other apps, the author continues to refine and update the app. It is even better than the physical 41cx device!
