12C-FIN

This is one of my favorite apps Amazing full featured HP 12C simulation at a great price Love having the 12C on my phone rarely use the real thing anymore this is better and certainly faster than the sluggish processor of the real thing Crisp clear display great options and I really like the highlighting feature of the f and g function keys and the portrait orientation Highly recommended A must have for any 12C user                 Highly Recommended

No problems on my iPhone 4s              Works great

We own two HP 12Cs which were made in the USA They work great and are solidly built I just bought a new 12C and cant believe how poor the build quality has become The keys are mushy and some are even unresponsive I went looking for a 12C app and downloaded this app to run on my iPhone I love it The graphics really recreate the 12C and has the added benefit of working in portrait layout which I prefer Unlike my new real 12C the keys on this app work every time and even have a nice click to them Nothing will replace the feel of a real quality 12C in your hand but the reality is this app is much more practical for use on the fly rather than carrying around a physical calculator For the price alone theres no reason not to have this app on your phone                 Better than the real 12c

DO NOT BUY THIS APP I purchased this calculator hoping that it would work when the developers other effort12C Classicdid not 12C Classic used to be decent before the version posted on Dec 21 2010 at which point RLM posted an update that basically broke the app for everyone The developer has been notified multiple times by multiple parties including me with no response whatsoever I purchased 12CFIN hoping that it would not be broken and would solve the issues everyone is having with 12C Classic but it exhibits exactly the same problems DO NOT SUPPORT DEVELOPERS THAT IGNORE THEIR CUSTOMERS RLM you should be ashamed of yourself You are basically cheating your customers Apple you should remove deadbeat developers like this and ban their apps from the App Store forever It reflects poorly on the user experience To sum it up This app and its developer are a great big FAIL     Do NOT support this developer

Testing here and the results are OK I just want to know which are the difference betwen FinCalc BusCalc and PlatinumPro app And the icon app is good not the same pictured here in iTunes                 Great financial calculator

I downloaded this after using the lite version forever however the retina display is nice it doesnt work in landscape properly Only a 14 of the calculator appears making it useless This is very odd since the calculator is supposed to be in landscape Please fix this bug     Landscape mode broken

Faithful simulation of the HP12C with a bunch of useful extra features This is one of the first apps I bought for my iPhone 4 and it has worked flawlessly from day one I use it all the time Five stars from top to bottom If you like RPN and especially if you like the 12C get this You wont be sorry PS Mac version is excellent too                 Wonderful Tool
