12C Financial Calculator

I'm a heavy 12C calculator user and I like this calculator a lot. I have a copy both on my Windows Phone and Windows 8 computers and it serves as an excellent substitute for my real physical 12C calculators. I would like to see the author change the fonts on the keys from Times to a serif font. The author of this app should be congratulated for following the Windows 8 design language (Metro).

This app doesn't work with an attached keyboard. I use a touch ultrabook, not a tablet, and this app is not compatible.

There are other similar programs but this one is user friendly. Some of the other programs look sharp but this one is the better one. I am deleting the others. Now I am looking for a 15C program for my electronics tasks.

I miss only one thing, the calculator don't record the memory and programming when we close it. Please change it.

This won't accept input from the keypad on my keyboard. It only works if I click on the numbers with the mouse. Useless!

ridiculous!!! what a waste. click with mouse only, no keyboard inputs possible. waste!
