Vicinno Financial Calculator

Manuals are for the HP12 which this allegedly emulates but looks nothing like and has none of the corresponding key functions. Thanks for wasting my time. Complete mystery on how to use it.

I bought this for the product it was and the UI was a major reason. You cannot just introduce a new product to replace what was purchased without giving the consumer the option to decide.

The UI dramatically change in the last update and now it is nothing near to what I liked it in the first place. I would have not gotten this App as it is now. I feel that I was fooled. You buy one thing and then they switch it for another. There should be an option to downgrade or retain the old UI

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.
