From the current Store description:
Powerful simulator of the classic calculators for Nokia and Windows Phone terminals. With advanced features and very easy to use.
* Trig functions in degrees, radians or grads
And, in case you'd been following this application through previous iterations, here's what's new:
- Added a free calc version.
- Key sound selection
- New window with new changes info
- Min key is fixed
- Key sound is now on press tap
- Added copy to clipboard
The end result is rather spooky to see on your phone screen, especially given the form factor similarities between these calculators and modern portrait-mode smartphones.
The developer does say that there's still work to do, namely:
- implement arithmetic precedence operators
- fix grades button
- fix parenthesis button
- support for new screen resolutions
- add new modes/skins
A terrific work in progress and a jolly useful trip down memory lane. You can grab Classic Calculator in the Store here.
