Vicinno Financial Calculator App Reviews

I worked at HP and my trusty 12-C helped me all the way through my MBA program. Its still in my desk drawer. But with this app, I have my 12-C and my phone in one convenient piece of hardware. Bravo!

Much faster than original one with classic graphic interface. The developer did a great job and keep updating the app. good customer service!

After reading so many bad reviews on the other HP 12 Apps including HPs crash happy one, I was a bit nervous. But, so glad I found this stable functional version!

No need to carry my old HP 12C. I love having this app. It does everything I need (present and future values and payments) that I need, and a lot more that I dont (yet). Im so glad they developed it.

I have been using a 12c for 30 years. It great to always have it with me. Customization of colors and sounds would be awesome!

Love the interface and ease of use!

Have depended on my two HP 12c calcs for years and dreaded having to carry both a cell phone and the HP back and forth. This app takes care of that and does it very well. It even has its own user guide, helping eliminate the big HP guide, but of course HP explains all the possible programming on the Magic Black Box. Sound is easy to turn down: just use the down/up buttons! As for the light keeping wifey awake, get outta bed! The only drawback is the small size, but that is limited by the size of the iPhone, not any problem of the app.

Same visual as regular HP 12c. Saves me from carrying around actual calculator. Love it!

no complaints except the annoying splash screen

Excellent. Very handy to have on your phone when your HP is not close by. Same function, same accuracy, speed at a fraction of the cost.

...really...

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 users manual is included as it makes it very easy to refresh my memory on how some of the functions I dont 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!

Works just like my old, well-worn HP except you dont have to replace the batteries in this app!

This is a great app that I use regularly. It works just like a real 12C and is every bit as reliable.

There just isnt a better calculator that an HP 12 C end of story!!! if you dont know anything about reverse polish notation you dont know anything about financial calculators Greg Strahan owner Vail Property Brokerage

As a Certified Financial Planner I use this tool every day. I have the HP tool and the app and they both function extremely well for my purposes. I use it primarily for time value of money and future value calculations.

Yeah, youre probably an older financial person, or trained by one, if your desk has had a 15C on it and isnt the same without it. This is almost as good. It really works.

I use it for real estate mortgage calculations. Works perfectly. Highly recommend.

Simply fantastic. I can carry my 12E and 15C with me all the time. All in my iPhone 6s. Worth every penny!

I use another HP financial calculator at my desk, but when Im away from the office, this app makes it so way to run scenarios for clients. Great app.
