Thank you so much for your latest version which has updated this invaluable app to me to be iOS 11 ready This was a most pleasant surprise as I ve been actively looking for an alternative Thank you also for making this a free upgrade to your established clients                     Updated for 64 bit Rebraun

V4 1 is awesome Has all the capability you would expect and more I use both on my iPhone ipad In my opinion poor reviews are written without merit by folks not setting added software options or toggling core hp feature sets as you would on the actual calculator Developer I would like to try finance center too but 9 99 is too much At 4 99 it s a buy                     Great update JRC1977

I updated this app as it finally supports iPhone 5 but then I found the currency exchange function is not working at all The exchange rate is always 1 0 whatever currency I choose to convert Update the support person said they will update the app and solve couple issues I told them about the currency conversion issue After latest update This is not resolved at all Terrible         Currency exchange not working after update Jimmyt01

Have used this for a long time Great app The adaptation to the iphone 5 screen size made the key use easier                     Great app torsod

This is no longer a 12c Stuck in algebraic mode Where is RPN Lost that realistic look Ugh Go back to the old version         Terrible Update Tomarti

In the last update the way to make any calculation changed from a beautiful 2 ENTER 2 to the normal 2 2 This changed the product that I have bought One star if you bring back the old way lets go to five star And if you are looking for a 12C clone don t buy this new version     Why did you change the behavior Leo Martins 13

As Pee Wee Herman once said Everybody has a big but the upgrade is very nice and easily switches from algebraic to RPN although I had to figure out how my big but is that after the upgrade my icon constantly says waiting i can only access the app by open command from the app update page                 nice upgrade but GuidonBookmaster

Stinks now that it s switched to a non HP format HATE it now     What Zero stars EllA9798

For most of us RPN lovers this is annoying one must select silver Platinum mode then select RPN via f CHS keystroke then you can turn Platinum off and go back to Gold Version Also the Begin End and M DY indicators are on the display and can t be removed that I can see On a normal gold 12C when set to RPN and g End and g M DY there should be no indicators in the resting display Only if in ALG and Begin and D MY should the indicators be present Annoying         Defaults to Algebraic yuk Reme18MZ

The Reverse Polish Notation Enter key is gone and replaced by the key I have been using this App for many years and very happy until this last update Please restore the RPN function     Broken JeanPierre

Super update to a program I use all the time Replicates the 12c beautifully                     Great update Hanwork

Having been a long time user of this app so that I no longer have to carry my trusty hp12 c around I was dismayed to see the reverse Polish notation that the 12c is famous for is now gone The enter key is now an equal key Things aren t functioning properly There doesn t seem to be any email link either on iTunes or on the developer s website which is extremely annoying Perhaps a one star review will get the developer s attention Please fix this     What the h Seems screwed up after recent update Lgqwerty

Don t do the update it is not working properly on my iphone 5 nor my ipad I had to restore my las back up to get the old version that works PERFECT     Dont do the update Jeronimo Huerta

Why I can t re download in my iPad since I ve already purchased the app     Can t re download RicardoPereira7

Works fine but needs an update for the iPhone 5             Good app Slumdog Billionaire

The best version I ve seen But PLEASE updated it for the iPhone 5                     My Favorite Calculator John LaTessa

Great financial tool I use it almost every day Has features beyond the original HP version options pricing etc Very nice help section especially useful for those not to accustomed to RPN The only thing keeping it from a 5 star rating is lack of iPad version                 Platinum Pro 12c Wayne Dwight

This product has not been updated to take advantage of the new and bigger screen of iPhone 5 Can I get my money back please     Small screen RCL CLX

Why does the new version have a very long lag between keystrokes     Lag between keystrokes too long Pr112

Loved app until installed 3 4 update now won t launch in iphone                 Version 3 4 crashes on iPhone RG2JH

Great item saves money works great                     Hp12c dudiz33

This is a great version of the 12C one of my favorite HP calculators I love working with it The new features make it the best iOS version My only wish would be that the developer would make it a universal app instead of just ipad compatible That said it looks great on the iPad and the orientation lock is a great feature Programming is very easy with the new Program Editor feature Vast improvement from the earlier version                     Very worthwhile App bquin

All of the updates to this app are fantastic except the lack of autorotation The 11c and 17bII apps do it Why doesn t this one Also the sound effects are a little annoying but they re easy enough to turn off Other than that this is a great update                 No autorotation privacy freak

I love apps that just work It is nice to get an app that does what is supposed to Their graphics are unbelievable especially if you ever owned one you d know what I m talking about Here is their caveat their customer service Some other apps are good but for customer support they may not be as good These people are out of this world I have needed them only twice since I bought this app in 2009 I needed them this week when I switched platforms and their attention was like I m brand new paying again type of customer For the price that I paid in 2009 I still get VIP service Don t debate if you are looking for a 12c don t go any further You ve found it Not only that their counterpart calculator for the computer is equally as good                     Best Financial App By Far The Property Manager

I use this when I don t have my HP with me Works great I would really like a update for retina screen 5 stars for that                 Great replacement to real thing Jasonovich von Hackelberg

No updates get real     Update for Retina Already GoBigGreen

The program does not calculate payment acurately There is a problem as to how it reads interest     Big Problem RICHARD ORTIZ

I like the function just like the one I have in my desk But I can t seem to get this app to rotate in the horizontal view                 Works good but can bmfuller03

Great piece of iPhone software I have been in commercial finance industry for over 25 years The HP 12C has been the calc of choice I have used this iPhone version exclusively for over a year and have found no difference from the original Well worth the price Get it you won t be sorry                     Beautiful Fast Accurate Mojoarno

I have absolutely no use for any of these advanced features but I still think this is cool I bought R L M s 10BII and the 12c Lite when it was free Maybe if I stopped spending so much money on this stuff I would have real money to play with                     This app made me buy a real 12c Platinum dutynco

I had the physical version for years this makes the itouch complete Great implimentation I m very pleased                     terrific daschles

Beautifully rendered Just like the real thing And a free desktop version as well                     Beautiful app Ronin_neko

Really disappointed I ve used a 12C for over 20 years and was really excited with these reviews Even upgraded for it Now it won t copy onto my I Touch     upgraded just for this and still doesn t work slippers77

This app rocks Not only does it look and work like the real thing but also includes mem and register snooping ever wonder if you should hit x y or not Oh yeah and the best part SPEED IRR is nearly instant doesn t take forever anymore of course I grew up on the old school model I heard Platinum is a lot faster Well worth 10 Now at 6 even better I wish they d let me use this on exams                     Better Than the Real Thing 12Cer

They promised to send me the serial number so I could register their 12C program on my IMac I have been waiting five days and have not received the registration number back yet     They don t keep their word Big Bob 5

Great application Tested several functions worked perfect even faster than my classic platinum 12Cs Great buy                     HP 12C Done Right Mentality.com

It is the real one                     Excellent Danielzs74

This is undoubtedly the greatest financial calculator of all time Great representation Now I don t need to bring my work calculator home to study Like the other reviewer I bought the physical calculator at Costco for 65                     MBA Finance student MBA Finance student

This is awesome I had the hardware version lost or stolen and this works the same as far as I can tell The only difference is I paid 65 00 at costco and this was 9 99                     Pure greatness ilovemusic99999

I just bought the real platinum 12c This app works nice I wish the clock banner could be disabled and also the portrait mode I bought the other 12c too which I like better for the above reasons The Platinum acts a bit different and this version works just like the hardware counterpart                 12c Platinum Finally Inv pro
