Glad I didn't buy the other RPN calcs which are uglier and/or too expensive! This programmer is amazing! I am probably going to buy the full version. Just suggest to pretty up the app icon.

懐かしいあの名機をぜひ！

Need for the best Financial Calc

I would love if you could develop the model HP 19BII financial calc for the iPhone

Version: 1.2

Best financial pocket calculator  
By: Torotrak - 28-Nov-2008
Version: 2.0
This application is a perfect copy of the ever best financial pocket calculator, since 1981.However, the version 1.2 Lite was much more complete.

Sound is too loud  
By: jmcheng - 21-Sep-2008
Version: 1.0
The calculator works like the real thing, but the keypad tone is too loud and sounds rather funny. There is no way to turn off the sound.

So cool! It´s a classic

If you have used this calculator IRL this is like a trip back in time. Nice!

Un decimal  
By: Pedrogar - 19-Nov-2009
Version: 2.2
Me he llevado la desagradable sorpresa de vr que los resultados de las operacones se redondean a un solo decimal

I love it  
By: Pete from Port Macquarie - 13-Jan-2009
Version: 2.0.1
HP RPN calculators have been my calculator of choice since the 70's. I used a real 12C for years until it died. This app is fantastic and incredible value for money. Key presses register just fine for me. Thanks.

PAS FIABLE

enorme bug dans la Touche des mois ( "n"). Elle ne marche pas convenablement. Cela a été signale il y a 6 mois et toujours pas de changement !!!! Bravo la réactivité des developpeurs Mieux vaut s'abstenir d'acheter cette version ( même problème avec la version Premium)

Leider nicht mehr umsonst...

Great, Specially for free  
By: CanadianNBiphone - 12-Sep-2008
Version: 1.0
Well it works pretty good,Now that is once you get to know how to use it, However once you get it its pretty straight foward.For Beginners, this a business calc, so for 12 divided by 8You have to do 12+8 and then the dividing sign,

Muy buena  
By: Lemalema - 28-Dec-2008
Version: 2.0.1
Muy buena aplicación pero le falta la función para convertir tasas de interes, por lo demás, excelente

Great application!

Once 12c always 12c, but I will still keep the real one, though I wonder if I will ever use it again. Thanks and well done.

Too slow  
By: Dexterss - 04-Oct-2008
Version: 1.1
Nonfunctional. Free 12c 15c 16c were much faster in 1.1.4 jailbroken iPhone.

この再現度で無償なのがgood  
By: typocoder - 07-Oct-2008
Version: 1.1
hp12cライクなRPN電卓です。まだ少ししか触っていませんが、かなりの部分が再現されているように感じられました。・RPN電卓を使いたい方・hp12cじゃなきゃ金融電卓じゃないと思っている方・hp12cの購入前に使用感をチェックしたい方・複利計算など、金融系の計算をしたい方以上のような方に、おすすめです。------v1.1で、キー入力の速度について改善がされました。速度に関するストレスはなくなったのですが、当たり判定というか、キーの幅・高さがやや狭いのは変わっていないように思えます。もうちょっと広いほうが叩きやすいかも。
