Best and most comprehensive financial calculator on the market
Highly recommend
Not for iPad
The description says it is optimized for iPad but it’s not. The display is fixed for portrait, does not fill the screen and looks fuzzy. I uninstalled and will try to get a refund.
Glad to see the update!
I have been using this RPN calculator for a number of years and I love it! Great for engineering calculations, conversions and financial. This is a great product for a die hard engineer that grew up on RPN! Thanks for keeping it going!
Excellent Calculator
Once you’ve learned RPN, you can never go back. This calculator is very easy to use and super reliable. If you know RPN, you’ll be very happy. If you want to learn, this calculator is a great reason to make the jump.
Great calculator !
I’ve been using this app for years, ever since I lost my HP41. I only got it as a temp, but it quickly became full time. If you like using RON, you can’t beat it. Plus, it’s got a lot of features my old HP didn’t. I find the conversions very helpful (cu yds - cu in, km - mi, etc)
Awesome RPN calc
I’ve been using this app for quite a while and love it!! Thanks!
Love this app
Really nice if you’re used to RPN calculators. I use it daily.
AllRPNCalc
For my needs, this is the best rpn app I’ve used.
Super duper awesome in all the right ways
Comprehensive features, intuitive settings, and a natural user interface. Well thought out and developed calculator. Thank you!
Outstanding RPN calculator...
If you like HP calculators, this app should serve you well.
I have been using this calculator for years, and it remains one of my all time favorites. It takes a successful HP calc and adds several useful features: unit conversions, currency exchange rates. I also value its ability to perform scientific and financial calculations.
I have tried and used more than 20 calculator apps. Some do offer features not in this one. However, it is in my top two calculator apps.
So glad the developer has updated this app to be compatible with current iOS versions. Hope other legacy app developers will do the same. The fear of losing this one kept me from being willing to update to the latest iOS.
UPDATE: Been using this great app for years, and it never lets me down! Kudos to the developers who have kept this app working throughout all the many iOS changes by Apple.
