2 serious flaws

This version 1.1

1. Key clicks are deafening.

2. No Copy/Paste.

These are easy things to fix as there are existing APIs to simply solve the problem.

Yes, you can turn off the key clicks in app. But then you have no app feedback. You can also turn the iPhone system sound down but, if you forget to adjust your system sound after using the calculator you may miss a call. Plus, if you use your calculator like I do, you will be adjusting your sound many times a day.

To HP: just let the user adjust the sound * in app * and maybe pick from a dozen key click sounds. The app key clicks are TOO LOUD!

No Copy/Paste? Its standard on every platform and blatantly missing here. It should include [Copy, Paste, Copy x&y, Copy stack]. Please think to make it ready to paste in a portable spread sheet.

A 3rd serious flaw is not including the manual. Im familiar with the 15c but, others may not be. The original manual is rich with content and will more than justify the price.

I purchased the HP 15c app because its a marvelous calculator -- I still own and use the real original. The app though needs improvement, and HP has been slow to react.
