Vicinno Financial Calculator App Reviews

Very nice app, happy to leave my 12C in the desk drawer...

This app was great until tonight. It suddenly quit working. Enter key, XY and other keys are sporadic; entire bottom row of keyboard isnt working at all!

I love this app. Best call app out there. Looks just like my call on my desk and functions so well. Meet worth every penny....

Ive owned a HP12C for over 30 years. This is even better!!

Ive kept an HP12C at my desk, in my car or in my pocket since I started in the commercial real estate business 30 years ago. I still have my very first one and even bought a spare. Theyre an irreplaceable tool for analyzing and evaluating investments in my opinion. So it was with great pleasure that I found this App for just $5.99 that handles everything I do on my HP, with the same familiar layout and key stroke sequences - and now its right on my iPhone. One less thing to carry. PERFECT!!

Its my go to calculator app. My hp is on my desk & this is on my phone. Besides, I never did much care for equal signs.

I have used this app for several years. It replaces my HP12c many times because I always have it with me and works exactly like the calculator does. It is a great tool!!! drbob

Great app. It works just like my original 12c. Now I always have it with me.

Ive been using this app for years. Works flawless. Its my most favorite calculator ever

The HP12C is the best calculator ever designed. This app emulates it perfectly. I will be using this app 30 years from now just like I am still using the original calculator. Even if nothing is changed from this point forward.

Owned and used HP12C for 20 years. This app is flawless. And, its much faster than original. No batteries to buy either.

It works exactly the same way as the actual calculator. I have not tried any programming though, so I dont know if the programming aspect of the HP12 calculator also works in the app. Other than that I have nothing to add. I love the app.

This app freezes more than it works, and the calculator buttons just stop working on my iPad. This is USELESS for an expensive app. Do not buy this rubbish.

After buying the app and after a few minutes of working with all the features of the app, it stopped working in the horizontal position. Tried with autorotate on tried with the it off. Not working in the horizontal position. Works great in the vertical position but am used to the original horizontal position. And after paying for it Id like all features working.

It has been 34 years since my first HP 12C. Th set calculator I ever owned. Still keep one on my desk. But it is great to have a virtual duplicate with me on my phone no matter where I go. A terrific value!

You cannot find a better 12C emulator in the App Store. Buy it! I use this 99% of the time; the other 1% of the time I use his HP 15C emulator. Good job.

The app works just like my HP12c, only its much brighter, the keys work much better than the buttons on my ancient physical calculator, the values on the display screen are easier to read than the scuffed up screen on my physical calculator, I now have several options to grab (iPads and iPhone with the app), and my iPhone is always close at hand when I need to use the calculator. I much prefer the app over the simple calculator that comes standard on the phone.

Wow - after using the 12C for the past 27 years this seems weird but is just like using the real thing. Only difference is the keys on the digital device dont sound "sticky" like my 20 year old 12C

I used this for my finance class instead of buying one. Its just like the real thing

This phone version is great! It means I dont have to carry a phone and calculator at the same time. On the large I phone its the same size as the original and sound effects prevent typos. I love it.
