この再現度で無償なのがgood

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。

Really nice app.... Just a couple of things to improve it....... Make the buttons better - hard to press which makes it annoying, change the icon - it just looks bad and add acelerometer functionality - like the normal calculator that comes with the iPhone or iPod touch!

Wow

Had a 12c for 20 years and still using it This is just the same but faster and inside my iPhone. No programmable feature but I use excel for anything like that now. Must buy for any rpn user and if you're still using algebra here's an opportunity to switch.

Great calculator

I would recomend this app, which is very cheap and usefull. The 12C lite works fine and allows me to use a business calculator anywhere I need. I think i wll never need my HP12C again...

Perfecta

Un aparato menos para llevar encima. Es perfecta. Y si que se puede cambiar el símbolo decimal

Great 12c Simulator

I have been looking for a HP12c simulator that doesn't have acknowledged bugs and doesn't cost $23.99. Here it is! Great job.

Génial!!!

Marche très bien. Une HP12c dans son iPhone. Indispensable pour moi qui ne calcule qu en RPN!

Would gladly pay a few dollars for a full version

Lovers of the Voyageur series of HP calculators (such as the 11C, 12C, 15C, and 16C) already know that RLM produces excellent desktop based emulators of all of these calculators. A lifetime subscription to RLM software can be purchased very economically, though it seems unlikely that this such a subscription will apply to AppStore downloads given the special arrangements developers must make with Apple to get their work posted here. The good news is that we know that RLM has source code for calculators other than the 12C, and hopefully we will soon see iPhone versions of the others, particularly the cult-favourite 15C (I paid almost 400 bucks for a near mint one--they are that beloved by collectors!)As for the 12c Lite, the only "flaw" in it is that it IS a Lite version, and at the moment a fully appointed paid version is not available. The lack of persistent, continuous memory is really a drawback, especially if, like me, you like to write programs. The same concern applies to cashflow problems--if you want to keep data in the CF registers between instances, you are out of luck. That said, the interface is beautiful to behold, and for those used to typing accurately on the iPhone QWERTY keyboard the smallish keypad will not be any hardship. 12c Lite seems to use the iPhone CPU, which means that complex calculations and programs run faster than on the original calculator.I encourage all lovers of HP calculators to download this fine app and support its further development by purchasing the full version when it comes out. Also, please write Mr. Matte to encourage a release of the other Voyageur emulators. I know I have!Edit in Reply to BabeBooth: I do admit that the built in landscape mode calculator is very good, offering double precision display and some excellent extended functions. However, comparing the 12c emulator to this is apples and oranges. 12c lite emulates a classic HP programmable financial calculator that uses Reverse Polish Notation as its entry system. This system involves a four line stack to hold intermediate results that is well known and loved by lifelong HP users. The built-in iPhone calculator is a scientific calculator, uses algebraic entry, and is not programmable. They are totally different things, and calculator and calculator simulator aficianados readily see this. I have no problem with your opinion, but in this case you facts are just plain wrong. The calculator buff loses nothing by trying out this free download.

いいアプリです

仕事柄、金利計算する機会が度々あり今までは国内メーカーのものを使用していました。 ＲＰＮ電卓は初めてなので全く分かりませんでしたが、ネット上で探してみるとＨＰ のサイトにＨＰ-12Cの日本語マニュアルなどもあり、内容を確認した後に購入しました。 当アプリではプログラム機能が無いのと、全体的にキーが小さめなので押し間違いに注意がいりますが、機能的には充分間に合っています。

Great

If you ever used a HP 12c, you will be very happy to use it on your iPhone!Really the best financial calculator! Specially in RPN mode...

Does everything a 12c is supposed to do except the programming, only without the delay of the real thing. I have been using it for a year without any problems. Higly recommended.

Perfect

Really. I'm not kidding. As good as having my 12C with me. In fact better because it's miles faster. No more "running" messages...Incredible.

GENIAL

Está superlograda. Para los que seguimos usando la HP 12C y la consideramos la mejor calculadora financiera de la historia, es imprescindible. Solo le falta una cosa: poder cambiar el separador de decimales; viene con el punto (.) y no se puede poner la coma (,). A algunos, nos parece importante. En la real se conseguía apagando la calculadora , manteniendo presionada la tecla del punto (.) y apretando ON ( pág. 17 del manual de la HP12C).

Much improved

The first version of this app was very slow to register presses on the keys. The current version is pretty good. Well anyway, I like it. Now my old 10C can stay in the drawer! Worth trying.

Trop de bruit / Soudn is back

With this new update, the sound is back... It's quite a shame to buy it @ 1.59€ and get a noisy calculator... It should be free !!

Absolument fantastique !!

certes, les régistres s'effacent lorsque l'on éteint l'application, mais pour le reste c'est génial. Tout est là. Il ne manque pas une fonctionnalité à la HP12C classique. Cela marche très bien (j'ai essayé pratiquement tout en reprenant le manuel de la HP12C). J'attends la version payante en espérant que cela ne sera pas trop cher !

これで反応がよければ最強

私はもう一つの sci 12 を購入しました。現在は価格も下げられてますが、まさか無料でここまでの物があるとはびっくりです。難点はキー反応が遅くて入力にストレス感じるところ。それがなければ最強です。7セグメント表示もレトロ感があって好きです。
