Vicinno Financial Calculator

Just identical to the original calculator at a tiny fraction of the price and it is always with you on your Iphone

I know it sounds hard to believe, but I'm qualified to say: this Financial Calc is not just better than others, but better the real thing, that I still have in front of me after 25 years or more. It reads better, it can be totally silent (unless you like it otherwise), and it works even in the dark (although I'm lucky my business allows for doing calculations in daylight). Forget X-Cell, as long as you can and fhe task allows you to: this one's the Steinway Grand Coda of the thorough accountant, sales person and cost-conscious manager.

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.
