Pros and cons of Calculate: Advanced Calculator app for iPhone and iPad

Calculate: Advanced Calculator app good for

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.
This app is awesome for scientific calculations. Thanks for this app !
Very good engeenering calculator. Have kilo, micro, pico etc. Good for electronic stuff.

Some bad moments

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.
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
Does what I need to do. Able to replace my Casio fx-300. Easy to use. Simple user interface
I am a university student and have searched a bunch of free calculators apps online, however, this app is a perfect match to my work. This calculator is powerful 2 line view and includes some of the most essential features of an easy to use calculator. 5star to the creators and thanks for making it available for free.
Great job , need an update to get the full screen for iPhone 5.
The calculator would be really great if the clicks were not that loud and if the bottom keys would fit iPhone 4 screen.
