Vicinno Financial Calculator Positive Reviews

Good but some functional problemsBeen using this iPhone version for 3 years after using an HP12C calculator for decades. The 0 “zero” key requires a lot of taps before it works and the PMT functions to figure at the BEG (beginning) or END (end) of period are buggy, also requiring a lot of taps to switch between these. Very frustrating after using the old version and liking it. I look forward to it being reissued. This is a very good calculator w a lot of functions but this latest bug fixes created some problems that didn’t exist before..PortlandiaNWVersion: 2.542

Excellent 12C financial calculatorIf you’re looking for or useful functional financial calculator with all the features of the traditional HP 12 C this is the calculator to invest in. I’ve been using a 12 C for decades from Hewlett-Packard. The original handheld calculator’s were high-quality superior products with innovative functions and quality workmanship. The latest versions are not likely to last very long physically and the workmanship and quality have become profoundly sad. I now want one device that works on my iPhone and iPad that I use throughout the day. The HP products are not supported with updates with the changing operating systems from Apple. They have annoying key clicks that you can’t silence without turning off all the sound on the iproducts, how pathetic is that. This is the calculator to buy! It’s supported with the latest operating system, there are no annoying key clicks you can’t turn-off, and the full functionality of the calculator is available no matter which way you turn your device to use it. The only complaint I have is the delay when you open the product because the developer runs an ad... but I am more than satisfied with the functionality of the product. Recommend you give it a try before wasting money on HP products that are no longer professionally supported..Shuttled CFIVersion: 2.530

Still faithful after so many yearsI’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..Hermy TwoVersion: 2.546

Great financial toolI started in the 70’s with the 38E, a high quality machine and then the 12C when it came along. My business requires that I have a financial calculator with me at all times. When traveling I always brought my 12C along but when the 12C app came out I downloaded it to my phone. As with most people I’m never without my phone so never without my calculator. Though the original HP 38 series was a better machine, for reasons I won’t comment on here, the 12C is very capable and an indispensable tool for anyone in finance. Everything I’ve written about the 12C is also true if the 12C app and I love the convenience of always having it with me. Thanks for doing a great job in designing your app to so perfectly replicate the original HP product..NotebossVersion: 2.546

My all time favorite calculator!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 user's manual is included as it makes it very easy to refresh my memory on how some of the functions I don't 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!.Henry Wallace WoodchuckVersion: 2.530

12CFor those of us raised and dependent on the HP12C, this has been a great addition until the update. In fact, my actual 12C hasn’t come out of my briefcase since I got the app years ago. This is just too easy. Unfortunately they just “upgraded” it to a new look. Keys are the same, but the background is completely different. I contacted them to see how to bring it back and was told they are working on having the classic view as an option. Ordered new batteries for the old 12C in the meantime... Update: The old familiar look is back as they promised. Thanks. I have been using this app for years, and it works just as well as the real thing..12c loverVersion: 2.543

Why change what works???Please go back to the previous version or let us know why you had to change to this??? I don’t like it. I hate software updates just for the sake of change as an engineer. If it works it works and a calculator should only be a calculator that works as intended. Changes often result in other problems and then another update and then more problems etc etc etc. Was this done in a effort to make more money somehow? Thanks for the retro update of the hp calculator. Not exactly like before but it works much better than previous version. Don’t change what works please and thank you..RomansDealsVersion: 2.543

Educational InvestmentWe need to be smart with our money. Learning to use this calculator, you will brush up (or, learn for the first time): the time value of money, opportunity cost, amortization and more. The Rule of 72 can get you close, but compound interest is too important to guess at. This nails it. Deciding of buy or rent a home, how much to save, when to retire, this is THE tool most popular (since the 1980’s) with people who get paid to give money advice. Nobody cares more than YOU about your money, so check their answers! Don’t worry about money, be confident..91169Version: 2.544

You can “Count” on this oneI Purchased the HP 12 C many many many years ago. In fact, it was the first year that it was introduced. It was phenomenal then. and went way beyond anything that you could do with a handheld device at that time. This application has all of the same capabilities as the original 12 C. I use it every day not only for my commercial real estate investments but for every day mathematical and financial needs. It’s easy to use and makes complex financial situations easy to calculate.I don’t know what I would do without it..SkeeterbooVersion: 2.546

Wouldn’t be without it.I have your calculator on both my iPhone as well as my iPad. I used to buy(for $89) the hp12c handheld calculator. No need to anymore. Your program is soooo much less expensive & I always have my phone with me. Keep updating. The 1st 4 days of the latest update the calculator wouldn’t work on my Iphone, just my ipad. Thanks for correcting that so quickly. I use it for finance, mortgages, and lease payments. Yes I was able to write the program to do leases. if anyone needs the leasing program let me know..JoeShawneeVersion: 2.542

Absolutely excellent! Perfect replacement for HP 12 CIf you are familiar with, or simply have used and miss being able to have an HP 12C calculator at your fingertips, this app is perfect! I could not recommend it more highly. Also, if you have an older version of the "HP12C RLS" calculator, it appears to no longer be supported. However, this app, the "RPN Financial Calc 12E", is a perfect replacement, and substantially less costly as well. The cost/value of this app far exceeds the older RLS app, and is far better choice even if the older was still available..Forever-and-a-DayVersion: 2.530

A faithful copyI’ve been using a “real” HP12C for close to 35 years and am very comfortable with it. This application is faithful to the original right down to the “running” status while the “calculator” searches for solutions. There are other calculators out there that calculate the time value of money but for those of us of certain age that began our careers with HP products, this is a comforting app to find. It’s a great value when compared to the HP version of the same thing. It’s my go to financial calculator for the iOS..DougW47Version: 2.544

Awful redesign! With pending correction.***Updated after developer response: I appreciate you guys reaching out. I have adjusted back to 5 stars, on the promise of the upcoming option to revert to the original look. Thanks.*** My only guess is that you guys received a cease and desist order from HP. That is the only way I can picture you making the decision to take what was the perfect emulator for a tool that I use daily, and turning it to this mess you have here. It's truly terrible..JailbreakingIsLegalVersion: 2.541

Great HP 12C EmulatorThis app does everything just like the HP 12C in my office. But for a very small price I can use it on my phone. Yes, I preferred the original interface, but can understand why they had to change it. It doesn’t make much difference because all the keys are in the same place if you use the landscape view. I’ve started using the portrait view instead and actually like it better. If you’re an HP 12C fan, you will be very happy with this app..TonysoarVersion: 2.542

Very good, but white haze on keys is annoying.I have been using HP calculators since the mid 1980’s in engineering, before TI took over the market. I still have and use my real HP calculators on a daily basis. Vicinno’s HP calculator emulators are very good and convenient on my iPhone, for occasional use. The only gripe I have is the white haze around the characters on the keys is annoying, and makes the characters more difficult to see. Please get rid of the white haze in future updates..HP FoolVersion: 2.546

Original layoutI like the way the calculator operates as it maintains the original RPN operation. The app has always looked exactly like the original HP12-c. However, the latest update to this app changed the overall appearance and I would much prefer to have the original HP12-c appearance as before. This is why I gave it a four star rating instead of five star. Please change it back..HuskersBobVersion: 2.544

The best!I absolutely love it and use it daily. RPN is simple once you get it, and saves so much time! For 1+2, type: 1 ENTER 2+ This is better because your mind naturally focuses on the number. So you enter the number to get it out of your head, then you click on what to do with it (subtract it, add, etc) - no more 'equals' sign. To change decimal points shown, press f then the number of decimal points you want. To clear history, press f and Sigma. Awesome..Lidia MonroeVersion: 2.546

🍀Just like the original🍀I've had this app for a while now, and it seems to be just like the original. Works flawlessly all the time, do not have to carry around the old original. Reasonable price, and look's sharp. I wouldn't be without this app now, I use it every day. If you like the old original you'll love this. I have two HP 12 C's but this is the one I use all the time!.Loaf fjordVersion: 2.544

Great AppFinally, a 12C emulator that works perfectly. I've tried others, most recently one that had an annoying delay between key press and display, as well as a penchant for crashing and freezing. This one works every bit as well as my HP handhelds, and I always have it with me on my phone. I also have it on my large iPad Pro, a blessing for my old-man vision..Trebor DVersion: 2.530

Love the app...miss the old interfaceI love this app. My 12c has not been out of its case in years. However, one of the things I like about the original app, aside from it’s perfect 12c functionality, is that it looked exactly like the real 12c. I may get used to the new look, but would love having the option to revert to the old. Nonetheless, I’m still a fan..CnxjwicjdiaVersion: 2.541

Great calculator. Like the Classic, but New Look has gtown on meWhen the Classic look disappeared I was upset. The new look at first was too dim. They fixed it quickly and told me the Classic would be back soon. Now that the Classic look is back, I am having a hard time choosing between the two. I have a real HP-12C, so the Classic look, for me, is visually consistent..Father of 7 DwarfsVersion: 2.543

IT IS LIKE A TRUSTED FRIENDI replaced my HP12C years ago with this app. It is true to the soul of my old HP12C. I started using it in grad school for my MBA and never looked back. This app is the only way to go for the business needs I had. I retired now and still use it for all my calculations. I’m so glad they fixed the old look. I prefer that over the new look hands down..Safeharbor766Version: 2.544

Great replacement for the real thingI grew upon the HP12c but now I only have to carry around my iPhone. I use for real estate and cash flow calcs. I have had it for 6-7 years and really never had an issue with it (unless you count the time I forgot to put one of the cash flows as negative)..Mebunn214Version: 2.546

Update = app support fixed! Thank you!!I bought this app years ago because of the product and how it worked, and I loved the calculator. This updated version won’t even open up for me. I tap the icon and it takes me back to my phone home page. Can’t even utilize it now. This needs to get fixed!!!.T.D.RothVersion: 2.542

Dependable CalculatorThere's only one thing I don't like...it freezes intermittently. Not sure if it's cause by my IPhone 5s 32gigs-halfway full with updated IOS 8. I recover functionality by doing soft reboot (turning off its screen). I emailed support but no reply. It comes with complete HP documentation manual. With its advance functionality features, the price is a bargain..Jar584Version: 2.530

Just like the HP12CHaving 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..Carl 894Version: 2.546

Love itAlthough I had a bit of trouble with it at the beginning because I’m new with 12C, I’m in love with it. It’s a very powerful calculator that I want you to have. That fact that I can perform on the go it’s really convenient. Happy with my investment (money and time to learn it).Fitillo2222Version: 2.546

Just like the real thingI started using the 12C about 25 years ago. This version is identical to the physical one, or even better. It’s a MUST download for anyone who wants to get percentages quickly, or for those who want to do more advance stuff like annuities, yields, NPVs, etc..Federico FastVersion: 2.546

Vicinno 12c emulation - just about perfectThe title says it all! I am quite pleased to have this functionality on my iPhone and iPad. I have the original hp device, but normally the Vicinno emulation is more convenient. My only complaint is as follows: the “key click” appears to be disabled on my iPad. Works fine on the mobile phone..JG GibsonVersion: 2.544

Replaced my 12cLove it works great. What else needs to be said other then if you don't know how the old HP12c calculators worked you will find this one strange at first and it will take some learning to make full use of it but once you do you will never want to go back to traditional calculators!.Bassman_2Version: 2.530

HelpI loved the app, until this latest update. It will not open even though my iPhone is running newest iOS. It is very helpful to have the calculator available on the phone. The functionality has been excellent. I have used the HP 12C since the early 1980s..ContextKingVersion: 2.541

It’s Baaack - ThankfullyThe original 12-C look as an option is now back, buried with the settings menu. It’s not quite the same as the old Vicinno app, so 4 stars not 5, but it’s close. The black-on-black design is gone and good riddance to a flawed aesthetic. Unfortunately it took weeks to get get back to where it was..PasCalCPAVersion: 2.543

Better than the originalWorks just like the HP 12 C. However, unlike the newer, lower quality workmanship of the HP 12 C, the buttons on this app never skip a beat. (my first HP 12 C I purchased in 1990. It listed for 17 years. The new were HP 12 C calculators have crappy keys that don’t always respond to the touch.).WGoldnergVersion: 2.530

Wow!I have used an HP12C most of my professional career even worn the numbers off the keys. This emulator is faster and more convenient on my iPhone. I purchased an older version that apparently updated and the new interface looks and works great. Thank you!.SwanSailorVersion: 2.543

The HP-12C you should really haveThis app faithfully emulates all of the HP-12C’s functionality in full-screen portrait and landscape mode. Users are able to toggle between the classic 12C UI and an updated version with improved character display. Links to user guides are also helpfully provided. I previously purchased HP’s version of its legendary calculator but sadly, it’s last update was over 3 years ago and doesn’t support full-screen mode in portrait. Other support is also minimal. This is simply the best HP-12C available and will satisfy all who use it..TorbikbaVersion: 2.546

Thanks for the update.Love the app. Had some recent issues but update fixed it. I bought it a few years ago and when I got the glitch I was disappointed but the update fixed it. Thanks.RayMiamiFLVersion: 2.544

Excellent calculatorThis is an excellent calculator app, with the look of the old 12C restored. The 12C look is not only pleasingly retro, it is also simply much clearer for seeing the buttons etc. It uses reverse polish number entry, which is easier for chains of calculations when you’re used to it..The_MinotaurVersion: 2.543

The classic is back!Just caught the upgrade as I was (optimistically) checking the site. Thanks for listening to your loyal users. Be sure to follow instructions after upgrading - you will need to reboot your device after selecting the classic theme in settings and, voila!.Hp12c fanVersion: 2.543

Great CalculatorI’ve been using the 12C since my college days in the 80’s, and it has been a great tool. This app is reliable and has been one of my top ‘go to’ apps for several years. I like the vintage look - thanks for bringing it back.... old habits die hard..Alan~1964Version: 2.543

Highly recommend.I’ve used this since it originally came out. Exactly as expected (if you used the original). Asked for the old look back, but now am getting to like the new look..WmBudDavisVersion: 2.543

Superior appI’ve had an HP12-C since they came out and it still works, but I don’t always have it with me so I need an app to emulate it on my iPad and iPhone as well. I’m so used to reverse Polish notation that other calculators are cumbersome. This app does the trick and it works very well..1-AVersion: 2.544

Great and useful!I’ve use an HP 15C since my first year of college. RPN is a hard habit to break. I had bought a 12C for B-school and that stoped working properly a year after it. This app always works as a good calculator should. Still have the original 15C still works like a charm, use it every week at least..SEC4685Version: 2.544

App stop workingStop working after about a week. Sent email to developer last week. Still no response. They fixed the app. Never contacted me directly. I am pleased with the app now. Don’t have to take my HP 12c out of the office now.ChrisjonessVersion: 2.543

It’s goodBetter would be bundled with the Mac app and maybe and instruction set..GenesiusxVersion: 2.546

Vicinno 12e calculatorThis is an excellent app for people who like to use an HP 12 C calculator. All the features and functions are exactly like the HP Claculator. The only downside that I've experienced so far is the app seems to get "frozen" every now and then..Psardana29@gmailVersion: 2.47

Vicinno Financial Calculator Negative Reviews

Changed to ugly design. No longer 12C design2nd Message: the developer still promising that the new update is going to be launch in a few days... another week as passes and nothing. Are you really are going to do it or shall I take this issue to iTunes and ask for a refund ? You may don’t understand but the only reason that I bought this calculator was the HP 12C design. More over when you have a Finance background where the 12C was part of our lives. One of the thing that upset me is these developers writing me for more than a month telling me that an update is coming where the 12C would be an option to change. Two updates have come, and that option is not there. If that option would not be included, be honest and say it..Atlantis1Version: 2.542

Why Change What Worked?The pictures show an HP-12C look on the left, and that’s what I bought. A few months ago, I noticed that the look had been changed. Now it looks like the second picture shown in the App Store. I didn’t like it, but I figured so long as it worked I’d still be happy. But it doesn’t work. The keys have become “sticky,” and as a result you can’t just tap keys and keep moving as had been the case. I would like the old HP-12C look, but particularly I would like to see the calculator work correctly. I would have rated it a 5-star App prior to your change..Mtn DaveVersion: 2.544

Latest update- don’t bother (with update)I loved the original 12c and have used it for a number of years. With the latest update, removed the look and feel of what I originally purchased, and even worse, they keypad numbers don’t even work. You have to press very hard (on some) numbers, and the decimal point doesn’t work. Update: Oct 16 the developer said they will update “in a few days”. It’s now 2 weeks later, nada. Deleting the app. No time for crappy products or service. You lost a long term customer. It does not work, and I use a calculator every day..DisappointedSonosUser#227Version: 2.542

Not happy with the changesPrior to the changes of the hp app, my calculator was working just fine. Ever since the change, I have a difficult time with the bottom buttons. I have to press them very hard in order for them to register. I use this for work and it is annoying when I have a customer on the phone that I am trying to get them figures. I wish I could get the old format back. I had no issues with the calculator before..Cup14cakeVersion: 2.544

Financial Calculator BundleI am happy with their calculator - it is a perfect replica of the HP Financial Calculator. However my disappointment is in the fact that I had to purchase this twice since my previously purchased version from 2014 would not update. From my conversation with Apple, Vicinno didn’t apply the update to the previous version meaning that the old version became worthless in IOS 11. I reached out to Vicinno but never received any reply. This is a nasty way to treat customers that buy your products that pays your salaries..Tony7296Version: 2.530

Do not like the redesign.Please update to give the calculator the classic hp12c design back. Do not like the redesign as I’ve used this for years as my phone alternative to the hp12c I use daily. Also, do not like that the manual feature seems to open a web search now instead of having the manual built in like it used to. I would use that manual specifically because it wasn’t a web search, so it was more convenient. Please fix or I’ll need to purchase someone else’s hp12c app to use instead..VargosaVersion: 2.541

Broken. Stopped working with latest update.12C emulator app will no longer open on my 6s+ running iOS 12. All I get is the ‘startup screen’ then it closes itself into the background and every time I try to select it from my ‘open’ apps it just ‘snaps’ back into the background. I guess I’ll have to look for something else. After installing iOS 12.0.1 it still doesn’t work. After all these years of only occasional use, I would like a refund if this will not be fixed..LpspeckVersion: 2.541

Bad updatePlease, fix urgent this app! I hated the color! It doesn't like a HP12C anymore. I can't type some numbers immediately, it doesn't respond right away to the dialing..RicohoraVersion: 2.542
