5/5Excellent 12C financial calculator
If you’re looking for or useful functional financial calculator with all the features of the traditional HP 12 C this is the calculator to invest in. I’ve been using a 12 C for decades from Hewlett-Packard. The original handheld calculator’s were high-quality superior products with innovative functions and quality workmanship. The latest versions are not likely to last very long physically and the workmanship and quality have become profoundly sad. I now want one device that works on my iPhone and iPad that I use throughout the day. The HP products are not supported with updates with the changing operating systems from Apple. They have annoying key clicks that you can’t silence without turning off all the sound on the iproducts, how pathetic is that. This is the calculator to buy! It’s supported with the latest operating system, there are no annoying key clicks you can’t turn-off, and the full functionality of the calculator is available no matter which way you turn your device to use it. The only complaint I have is the delay when you open the product because the developer runs an ad... but I am more than satisfied with the functionality of the product. Recommend you give it a try before wasting money on HP products that are no longer professionally supported.

5/5Still faithful after so many years
I’ve been using this app for many years. It is one of my daily go to apps. No exaggeration. I use this every single day. If you’re familiar with the HP-12c, you’ll be completely familiar with this. I’ve never had a problem with it. It just works. A special shout out to the developer. Years ago, they gave the app a new, sleek, flattened look. I wrote to them about the fact that, due to my vision, I couldn’t see the demarcation of the buttons. The developer restored the original look as an option, which you can find under settings. Thank you for maintaining that. Some may be put off by the unfamiliar way of doing a simple calculation using what is called RPN notation. In school we learned PEMDAS-based arithmetic notation to enter numbers for calculations. Try spending a little time learning RPN. It helps get rid of parentheses and you control the order of arithmetic operations. It’s better for any multi-step problem other than adding a simple column of numbers.

5/5Great financial tool
I started in the 70’s with the 38E, a high quality machine and then the 12C when it came along. My business requires that I have a financial calculator with me at all times. When traveling I always brought my 12C along but when the 12C app came out I downloaded it to my phone. As with most people I’m never without my phone so never without my calculator. Though the original HP 38 series was a better machine, for reasons I won’t comment on here, the 12C is very capable and an indispensable tool for anyone in finance. Everything I’ve written about the 12C is also true if the 12C app and I love the convenience of always having it with me. Thanks for doing a great job in designing your app to so perfectly replicate the original HP product.

5/5My all time favorite calculator!
This is a near perfect implementation of the HP 12C calculator, which I have been using since its inception. I have this app on my iPhone and on my iPad, and I have an actual 12C in two places in my home, so clearly this is my go to tool for anything financial. I really appreciate that the entire user's manual is included as it makes it very easy to refresh my memory on how some of the functions I don't use frequently work. And, I had to smile when the app was re-named to "RPN", because in brought back a memory of my then friend Donnie B., who was of Polish ancestry, explaining in great detail that the key sequence on the 12C was known as "Reverse Polish Notation". Congrats to the developers, this is a very well done app!

5/512C
For those of us raised and dependent on the HP12C, this has been a great addition until the update. In fact, my actual 12C hasn’t come out of my briefcase since I got the app years ago. This is just too easy. Unfortunately they just “upgraded” it to a new look. Keys are the same, but the background is completely different. I contacted them to see how to bring it back and was told they are working on having the classic view as an option. Ordered new batteries for the old 12C in the meantime... Update: The old familiar look is back as they promised. Thanks. I have been using this app for years, and it works just as well as the real thing.

We listen to you, and add the requested improvements as follows: 1. Add copy to clipboard feature, so the figures on the display can be easily copied to other apps. the reverse (copy to display from other apps) is not achievable since it is a calculator app and key tapping is the only way to input. (Sorry about it) 2. Change key click sound to a more enjoyable one. We are working hard on other requests; meanwhile, keep all ears for the new ones. Thanks for your great feedbacks and patience.
