Vicinno Financial Calculator

Agree with other comments don’t like new style..........looking forward to original style of keyboard as an option!! .........hurry !!!!

I have been using the hp12c for 36 years and so this new look and feel does not appeal to me. I know I have to get used to it but I did prefer the calculator look that I was so accustomed to.

Got my first HP in 1973, an HP35. Yhe Reverse Polish Notation makes everything SO much easier than direct algebraic entry. It is absolutely gabulous to have this app available.

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.

Calculator opens at about twice the size of my iPad screen making half the buttons inaccessible. No resize of scroll function available. Worse, no way to get refund! Do not purchase for iPad!

The calculator looks great. You can toggle the sound on and off, however I would really need haptic feedback on the keys to simulate better the experience of the original.

I’d give it 5 if it had a Split View on the iPad. Asked but never got a response.

Great function and fast, works just like my HP 12c

Being a banker and having app-12c calculator and now this app on my phone has being a great help. There’s one thing I wanted to use this App and that’s on my Mac. I would have to buy the App again for Mac. I think that’s not fair.

Having used 3 different HP12C calculators over 40 years in finance they are like my right hand in familiarity. This app is virtually the same in functionality. The only differences are the tactile feel of the keys and being able to use the ever-rugged HP12C case as a light duty hammer.
