Very nice but...

...it needs to be updated for the iPhone 5 !

Very good!!!

Of course there are many scientific calculators on AppStore. However, the user interface of this one is very good: 1) the most used scientific functions are directly accessible (no 2nd key). 2) the calculation is edited on the first row of the display when the result is shown on the second one. The display can also be scroll to see and reuse the old calculations. 3) the user interface is very comfortable and clean. A memory and a landscape mode would be useful.

一番良い

フリーの関数電卓の中ではこれがベスト。表示が大きくて高認識度、履歴も残るし、履歴を修正しての再計算も便利。マイクロ、ミリ、キロ等のエンジニア向け入出力も使える。クリック音も気持いい。

Number 1 and 5 Star

This app is awesome for scientific calculations. Thanks for this app !

Excelent!

Very good engeenering calculator. Have kilo, micro, pico etc. Good for electronic stuff.

Version 1.0 off to a good start

I was looking for a calculator that could view previous entries simply by scrolling up on the display so I didnt have to write anything down or memorize long answers. This app does just that, BUT this is the first version and it sadly doesnt rotate when I tilt my iPhone like the included calculator. Im hoping for updates in the future.

Perfect for those long assignments

The best calculator for working on those long, multi-step problems in university. Having the option to simply edit your inputs rather than having to slog through each step really makes the difference. Having the option of a clicky calculator or a clacky calculator also a plus. Thanks Joe, -Gore
